Background: Work bought me an S4, but they use Verizon...I use T-Mobile. I must solve this issue. (Plus it's been so long that since I've even opened my QXDM/QPST that I almost...almost forgot how to use it, man, I miss it)...
This is more of a running log to potentially help others in their endeavors. This is an advanced topic...by today's standards. There is a LOT you need to know before just jumping in on this...unless you're like me and don't mind bricking a device for the sake of learning...then, carry on.
BTW, As you can clearly tell..I don't do super formatted frilly assed colorful posts...
ONWARD!!
What is known so far:
1. The modem MDM9615m is capable of anything...(Maybe even making you tea).
2. Using either 2009031920090615 or 2010031619780721 as the 16 digit PW in QXDM allows you to use "Software Backup" to backup and restore QCN files...(Both work, only one puts the phone offline)
4. The AWS band method that is floating around here (337_aws.qcn) doesn't work...it actually breaks the phone. (more on that later)
5. Putting your backup on again leaves whichever fields the 337 file had intact...so say you put the 337_aws.qcn file onto the phone, it stops working...however, you restore your backup...and the phone starts working again but all the fields of the NV that were written by the 337 file remain. Though phone functionality is restored.
6. MDK or ME7...doesn't matter at this point...no effect on functionality.
7. Flashing an MD1 modem/NV Backup from a T-Mobile Note II (which also has the 9615 doesn't seem to work...yet)...It actually kills the phone...I'll update when/IF I revive it...
8. You can Odin your modem back...whew!
What needs to be explored:
1. Whether or not flashing (shoehorning) another carriers radio will help (or if it's even an option)...this would probably have to be a regional carrier or maybe an international (non US) carrier's radio. Usually the bigger carriers can tell the manufacturer what to leave out/put into their phone...
2. Which NV Items need to be modified in order to get AWS (maybe even LTE) working.
3. Can a backup of another phone....let's sayyyy a T-Mo S4...be made and dumped onto the i545.
4. What complications are there? Is this permanent, can the phone be put back to "normal"? etc. etc.
5. If, as a last resort, we can edit the current parameters that are in the NV of a stock i545 to simply "reroute" (work with me here)...what bands it uses for which function...(this is the most tedious...but most undoable method...that I can think of....so far).
Troubles I've already ran into:
As mentioned before...after you write the 337_aws.qcn file to the phone it's pretty much set in stone...for now. When this happens, the modem starts boot looping...I'm sure this is due to bad parameters since the 337_aws.qcn file was probably from a 9215, i545 uses a 9615...you will not be able to access it again in QPST/XDM...
You'll have to get into Settings, More Networks, Mobile Networks, Network Mode, and select GSM/UMTS...this will keep the modem alive for you to be able to play with it again.
So far that's it. I've only been able to start messing with this phone in the past day or so...so, I'm sure this thread will be my dumping ground for my progress/findings/ideas...etc. Again, I encourage anyone that wants to help....to do so. I'm always open for collaboration.
This is where I start filtering down and organizing what I'm doing.
I believe that the best course of action right now is to utilize the 9615m radio from a Note 2...and perhaps a ROM from a T-Mo S4...
The main reason is because when you flash the 9615 modem but still use a VZ Rom...it tries to force it into a "WCDMA Preferred" selection. Which as we know...isn't an option in the menu. However, it's still trying...but I think the ROM doesn't know what to do at that point (could be way off here). I'm thinking that there has got to be a specific combination that needs to be used....for example...a Note 2 modem with a Tmobile ROM and NV backup? or that...but with a VZ NV backup...
I'm not a programmer/rom guy, (I'm more RF engineering etc...), so I don't know if there are things in the ROM itself that dictate which options are available and how the modem is used...
More exploration to be done...
Build.prop indicates to the system what network options should be available
Tmo rom looks like the way to go
On these newer phones the modem dictates pretty much everything else network-wise

That's good information....I tried running Paranoid Android but it wouldn't boot and any other rom told me that the device ID was wrong. I'm going to look into bypassing that check and try some more...
It hasn't been fully proven/disproven but it seems that there may be a "hard" block for US CDMA devices to use US GSM.
It can certainly see it but won't connect based on the threads I read.
But I don't think anyone has documented it in thorough detail what has and has not been tested.
Now if that setting is in NV data and can be modified... you may have a shot.
But if it's something hard coded and/or physical (QFuse) it may not be possible.
Q: Would it not be easier to find someone to swap with you? Or sell the device and get a Tmo?

Haha, leaps and bounds! easier, but what's the fun in that? How will we learn what can and can't be done if we take the easy way? Plus...maybe someone runs into a stellar deal and can't afford a full priced S4...they might nab a VZ one for cheap...this could potentially help a lot of people...
This is more to learn than anything...
Any progress?
Any progress with this? I'm in the same boat.
Thats a shame. Would be nice to have found out if a CDMA S4 could be fully used with GSM network.

HSPA on this divi e. Not LTE.
It makes me confused that band 4 LTE is locked on the phone
I always thought verizon had the open access regulation from FCC and that's the reason all verizon LTE phones are gsm unlocked
in fact some posts indicates it's CDMA unlocked also. Some CDMA carriers use R-uim card such as China telecom,and people were able to insert the ruim and have cdma working.
From this post, it seems verizon only had the regulation on LTE 700 band 17, not AWS band 4?
or is it just because verizon hasn't really deployed AWS LTE yet, so the relative software hasn't been released yet?

just for clarification, Verizon uses LTE 700 B13 not B17. According to Samsung and some other website Verizon S4 support LTE B4 and B13. and according to the guy in this post http://forum.xda-developers.com/showpost.php?p=44206677&postcount=20 he is using or have used VZW S4 on T-mobile LTE.
This is one of the oddest things I've ever run into.
I can put a T-Mobile Sim in the phone and it works almost like it was a Verizon Sim with the exception of needing to switch it to global mode when prompted.
If I stick a GSM Metro PCS Sim that I am currently using on the M919 it wont connect to anything except Wifi.
I hate locked bootloaders.
What about with custom roms?

Sorry that was a typo, yep att use b17 and vzw use b13
Verizon is going to deploy a second LTE network using AWS spectrum in congested areas
Why you guys don't install "android data tool" to be able to enter the *#*#4636#*#* menu so you could set LTE only to see if Verizon S4 pick up T-Mobile LTE?
If you are rooted and have access to write system data you could edit the "sale_code.dat" file under system/csc and change from VZW to SPR, AWS or any other code, so you can have more network mode options under mobile network settings.
Just for some clarification... This is done on Stock Touchwiz rom or is the device rooted and / or rommed and loki-d

So I can put a verizon sim card in my tmobile Gs4?I thought Verizon didnt use sim cards like tmobile and at&t.my tmobile Gs4 is unlocked so basically I just need a Verizon sim card and a Verizon plan. Thanks!!!
Sent from my SGH-M919 using xda app-developers app
I don't think that works that way. Verizon is a CDMA carrier and T-Mobile a GSM carrier. Verizon sim card is for LTE only (LTE is GSM based technology). Voice works over CDMA radio which T-Mobile S4 lack of it. T-Mobile sim works on Verizon S4 because Verizon S4 is CDMA/GSM/LTE capable.

This is not an easy task. Unless you know someone that has access to Verizons databases, you can't activate the phone on Verizon.
Don't quote me on this, but I don't think that phone supports Verizons bands.

Activation is all through the SIM card for LTE phones. Odds are, the USC version doesn't support the proper LTE bands to work. I also think you're going to have problems using the CDMA network as well, even if the SIM card is recognized.

Nor for sure if it's possible with custom flashing but it's not stock. The note that I saw was heavily locked down. It had a sim card slot but that was about it.

First of all.... looking at this link below.... the SCH-i605 and the SCH-R950 are on the same bands.
http://www.gsmarena.com/samsung_galaxy_note_ii_cdma-5152.php
Second, I am also attempting to get this working myself. The SIM Card is not even recognized. I have my SIM from my Nexus and it still Says No SIM.
Anybody else want to lend some advice? I too would like this working.
A little more research. US Cellular did not want to give up their information to "Unlock the phone". Verizon's SIM does not work with the US Cellular stuff on the phone. It looks like that the partition needs to be setup with the Verizon PIT file. Once it is re-partitioned, then the rest of the phone should be able to be flashed to Verizon.
Am I far off base? Has anyone had success with Re-partitioning? The last 2 tries, it hangs at Get PIT for mapping.... or something like that.

Seems a little off that the partitions would be different.
I imagine it is CSC and maybe even EFS related.
Do you have a USC pit file? I'll compare it to the verizon one.
That's another issue. I don't have a USC Pit file.
I found an R950 firware update that may have the necessary PIT and CSC files. It's extremely slow... might not get back to this until late tomorrow.
Not included. Like I said before, the verizon PIT hangs at Get PIT for mapping on the R950. If someone can provide that file, I'm curious if it will get past that point.

Won't work without heavy SW work at the modem level and kernel. For 2/3G, they share the same bands (PCS/Cellular). LTE is on completely different bands (Verizon is on Band 13, U.S. Cellular is on Bands 2,4,5 and 12). Therefore, if you could hack it enough to get it to accept modified VZ SW, it would only work on 2/3G.
First up sorry to dig it out of the grave
but i saw some utterly famous guyz replying so thought of dropping my query as well.
I am gonna get a USC Note 2 , though i will primarily use it on cdma , but i was wondering if now ( its been a month since last reply in this thread )
the phone can be unlocked and can be used on a gsm network outside of country ,
i wish to just pop in any gsm sim in it when i am abroad and use that on it.
or if there i a way to make it work with the cdma sims outside of US.
would be grateful if anyone can shed any light.

It is unlocked for GSM bands domestic and internationally on supported frequencies.
For Domestic GSM/UMTS/HPSAP+ bands ( you ARENT locked to 2G , but you need to be on refarmed 1900MGHz bands for H+ in your area) I suggest taking a look at JellyBeans ROm 13 or 14.... Supports GSM bands and APN editor . I have my Verizon sch-i605 running on TMobile at 6MB+ down and 2MB+ up with text and mms with no problems at all.
TMO has no contract plans from $50-$70
Simple Mobile has plans from I thin $30-$60
both with 4G (AKA HSA+)
Its not an issue with verizon variant, but us cellukar vwrsion is tricky. Inserting an international gsm sim only shows unsupported

RE: As of 9-13-13, no luck still with Re-Part. working on clients R950 trying without root is the goal, but appears it is the only way. Manual Programming is also difficult. VRZ's pit file i605 won't map on R950. Soft bricked the phone after each attempt. Both phones operate on same bands for sure, but must have providers software installed for the LTE card to work. Not even sure how stable a root would be, but not going to attempt on clients phone......

Attempted something similar today, was told the phone does not contain a CDMA radio so no go for service of any type because it does not support the same LTE band also.
Even if you managed to get the radio working, the Verizon rep said that the phone is not on their list of allowed devices and a SIM would not activate over their network.
I've done some research on the topic but am having a hard time finding a definative answer on the topic.
I bought my phone thru Verizon (paid in full) intially to ensure I would keep my unlimited data plan. Since this purchase I've discovered that T-Mobile has s $30/mo plan that fits my lifestyle just fine. My intent is to sell my plan (craigslist/ebay/etc) to get out of our contract and make some $$$ on the side.
When I bought this phone 1 of the major draws I saw was that, even though it's a Verizon phone, it wasGSM compatible. I've read plenty of posts about users throwing in a ATT sim card and being good to go. On the tmobile side of things, the results aren't as clear.
So.... Long story short, I'm looking for a definative answer if the Verizon GS4 will fully work on T-Mobile's GSM network and if so, where might one find some guidance on what I need to do if there are any necessary steps involved.
Thanks in advance for any help.
Plain and simple... No, the Verizon GS4 will not work on Tmobile. Verizon is cdma and tmobile is gsm. It will not work

These questions are tricky. Work!? You have to define that word before you get your answer. Voice works and so as data IF you add APN manually (or if it comes automatically from T-Mo). Now by data you mean 2G(EDGE)? 3G(HSPA)? 4G(LTE)? It also depends on whether you are in an area where T-Mo has re-farmed 1900 HSPA. If you are in one of these areas then you got 3G for data. If not, 2G for you. No 4G anywhere for this phone on T-Mo.

Yes, it is %100 possible. It's involved...to the extent that it might not be for those who aren't willing to turn their phone into a PDA.
In this post I explain (condescendingly, because some guy was so sure it wasn't possible) that phones nowadays are capable of multiband...because it's just not cost effective for manufacturers to produce one phone for CDMA, then one for GSM, one for LTE, one for AWS bands, etc etc...you get the picture. If you look up the specs of the chips in the S4 (probably the same across the carriers) you'll see that it's a pentaband phone.
Short story long...I come from a time where there wasn't a "It's not possible"...my job bought me a VZ S4 which I plan on using with my Tmobile simcard...because I don't feel like carrying a Nexus 4 AND an S4...I'll post my progress in the forums for all to benefit from. Until then...
I only tested it for a few minutes.... but I did get lte on it but not sure about aws... on T-Mobile. Sorry I couldn't do a more extensive experiment.

how are you getting 4g? I'm only getting 2g ;-; i'v ebeen asking everywhere but everybody seems to think it cant be done i guess? I just get ignored by the usually helpful community.
I am also on hyperdrive, have you looked at their coverage map? And what apn are you using tmobile has 3. Standard phones, smart phones, and I believe one for hipsters aka apple? The proper apn starts with fast. (Its 645 in the morning google it yourself)
Another thing to consider, you might be getting 4g or h what ever, t mobile is half as fast as verizon. I had to use xposed framework to turn on the proper icons.
The steps I posted are all I did, other than being on hyperdrivre rom. Try setting to gsm as your preffered network?
Im sorry people have ignored this and claim its impossible, the tmobile guy in store actually got his manager to come use my phone after I got it working in front of him in store. The store manager told the employee I must be some super hacker and this isnt possible for normal people. All i did was imout the apn and the sim nothing crazy.

I currently have a Droid DNA through Verizon and would like to switch to Straight Talk. I see options for both AT&T and T-Mobile compatible SIM cards, and am curious which one I should go with. I live in the Houston area. I prefer not to have to cut the card but it's not a deal breaker.
In my area AT&T has much wider and more reliable data coverage. I was often on edge everywhere in my hometown while on T-Mobile. This may not be the case for Houston. Just test drive both networks for a month each.
Ah, excellent point. Should be cheap enough to try them both. Thanks!
I actually work in Electronics at Walmart and deal with this all the time. Straight Talk will not move 4G LTE phones to their service. They aren't compatible and do not have the agreements with carriers for LTE access. If you read the CDMA/GSM bring your own phone package that includes the SIM cards it says in bold writing LTE Phones are not compatible. The DNA would not be able to be used on Straight Talk because it is a LTE phone. Straight Talk has a list of approved devices on their website. Because you do have to provide your phones IMEI they will know it is a LTE phone and deny your request to activate the phone on their services.
Kutster, I hate to correct you but I actually did successfully connect my Droid DNA using the Walmart SIM card. Now in my area it was actually called FamilyMobile, and run by T-Mobile. I purchased a SIM card from Walmart, took it home, plugged it in, set up an account, and it worked. Granted, you don't get LTE, but it does work and is mega cheap ($40/mo unlimited). I ended up cancelling and taking it back, simply because the internet was very slow, and the coverage wasn't very good in my area (T-Mobile sucks in my area). I do want to stress though that it definitely does work! I think I'll try AT&T GoPhone next.
The important thing to remember is this phone (the DNA) has all the radios necessary to connect to just about anybody but Sprint's network. Don't always believe what the companies tell ya.

See that's where your terms and confusion of prepaid comes into play. Of course Family Mobile worked they don't have restrictions on LTE especially since Family Mobile is powered by T-mobile. Straight Talk which is the company I was referring to and the company you were referring to does has limitations on LTE phones, and will NOT allow any LTE phone to to brought to their service. This has to do with they license the use of multiple carriers towers.
Trust me I am not trying to be rude, but I honestly deal with this on a daily basis. You know how many Straight Talk bring your own phone kits I have had to refund because customers buy them for their nice Verizon LTE smartphones? It doesn't work. I am telling you from my experience and my countless hours on the phone with Straight Talk reps and on their website, what their policy is on LTE phones. I beg you to go to Walmart and look at the Straight Talk CDMA/GSM BYOP (Bring Your Own Phone) kits that they sell for $60. In the middle of that package on the front it says something along the lines of "LTE Phones are not Compatible." Which like it reads means you cannot bring over a LTE phone to Straight Talk.
AT&T prepaid I would venture to guess would work, but I can't remember if AT&T is as picky as Verizon is about what smartphones get put on their prepaid plans. You would have to call and find out.
So once again, please keep in mind that every prepaid carrier is different, use different towers, and different policies. Just because it worked on one does not mean a different company has policies that differ or block that same practice.
I didn't realize StraightTalk and FamilyMobile were different. I just assumed that when I went to Walmart it was whatever they were using. I see now that StraightTalk is AT&T and FamilyMobile is T-Mobile. I only had the option for FamilyMobile at my Walmart. Thanks for the clarification.
I'm not going to disagree, but I will say that the FamilyMobile website also said my specific phone was not eligible, but it did in fact work. So to anyone else reading this, YMMV. Considering Walmart takes the card back for a full refund, I don't see a problem in at least attempting it (except that employees such as yourself have to deal with it ). It makes sense to me that there's no way for the carrier to enforce specific phones when they are SIM card based. So long as your phone has the radios that carrier operates on, it should work. My guess is that the LTE phones statement on the package is in reference to the fact that you won't get LTE speeds with that network.

Being an an LTE device wouldn't matter in this case since the LTE radio will only work on the CDMA side of the phone and with Verizon's LTE. It has UMTS and Straight Talk already confirmed with me the phone would get 3G while on their network. There's not a magic way of them detecting an LTE phone ( one that works on a CDMA carrier mind you) and flipping the off switch. The 2G and 3G networks are available for AT&T and T-Mobile regardless of which prepaid carrier you use.

Im not going to argue about it. When you go to activate a BYOP on Straight Talk you have to input the IMEI, which does tell Straight Talk if the phone is LTE capable or not and if it isn't eligible it will not allow you to activate the phone. Period. I hate done it and tried it. It isn't like ATT where you put in the SIM card and it is activated. You activate the phone IMEI and SIM card # with Straight Talk. That is how it works with BYOP.
@Impala Im glad you had luck getting Family Mobile working.
Uh, I'm currently using Straight Talk on my DNA with full HSPA+ capability, as are many others.

Also, Straight Talk just got support for AT&T LTE. So they're going to have to accept LTE devices?

Yeah I just read up on that. I wonder if the DNA 700mhz band will work. I checked online and it shows AT&T as using the 700 bands as well (a,b,c) I'm assuming the new Sim they are selling enables the LTE?
Can anyone with the new Sim confirm LTE connectivity?
EDIT : looks like at&t is band 17 and Verizon is 13. The FCC is pushing for interoperability within the upper 700 but it looks as if the chipset controls which band LTE operates off of...damn. It would be sweet to get LTE on an unlimited prepaid plan.
Interesting. I wonder if GoPhone or anyone else that's AT&T related would work LTE wise?
So are you guys able to use gsm networks with the 2.06 firmware?
I'm using net10 (att) with my DNA with 2.04 firmware and I'm hesitant to update to 2.06 until I can confirm that the 2.06 update keeps gsm completely unlocked?

Hey everyone, I'm totally new to Straight Talk and GSM and the DNA being used somewhere besides Verizon. (I'm a long time VZ customer but read Android Police daily and am familiar with all things Android.) Anyways, I'm pretty clear on using the phone on Straight Talk, getting MMS and all that, my only question is, how do you go about getting OTA's? Since the phone technically is a Verizon phone, updates would come from them. While on Straight Talk can I throw a Verizon sim card in the phone, download the OTA. Then after completing the update, put back in my AT&T sim card. Or does HTC offer OTA downloads online?
How do you guys go about updating your phone? (OTA's obviously apply to non-rooted devices. I may or may not root it.)
Thanks for your help!

Is it possible to unlock the Verizon version of the S4? I'm deploying in 4 weeks and would like to use my phone with international carriers. I have an SCH-I545 build and I'm still running on stock. Thanks
I think ATT has begun to unlock phones internationally when asked.
Verizon? Not sure... one think to check is if the Verizon GS4 supports a carrier in the country you travel to.
Take a look at Leo Laporte's Tech Guy show... he has callers ask this quetion on average every other week... I think he has show notes on his site now days... techguylabs.com

Verizon phones are unlocked out of the box, but you have to make sure that the country you are going to has a GSM network.
After a lot of searching, I decided to ask this here:
I have a Verizon S4, but I was wondering if it was actually unlocked out-of-box or if there is something I have to do in order to use it with, for instance, Cricket, or U.S. Cellular. I have done lots of rooting/developing for Android, but have never tried to use an Android phone with a differing carrier. Can anyone help or point me to a thread that helps? (Again, did lots of Googling and XDA-searching)

The phone is GSM-unlocked. This means that you buy a SIM, plug it in, then add the proper APN to enable data. (Settings, Connections, More networks, Mobile networks, Access Point Names). The "+" (Add APN) button is disabled if you have a VZ SIM installed but will be enabled if you insert a non-VZ SIM.
Whoever you get the SIM from will tell you what to enter for the APN.
Whether or not it'll work and how fast a network you'll get depends on the bands that the local carrier uses.

HI k1mu,
So do you mean to say if I purchase this device with full price from VZW ~$400 (month to month plan),
the next thing I can do is take off VZW SIM and would it work on my AT&T GSM SIM in US?

Maybe. While the VZW version is GSM-unlocked for international use, it is unclear how well it works with US GSM carriers. Some people say they can get it to work, some say they can't. Theoretically, it should only take you putting in an AT&T SIM then plugging in the APN data for it to work, but some people still say it won't.
So, you should be able to, but going by the accounts of XDA members, it doesn't always work, which may or may not come down to user error.

Thanks joshm.1219,
It still leaves me in a dilemma.. I do really want to get a "S4 mini" model but don't want to stuck up with CDMA providers to be true. Might want to use with ATT or Tmobile or H2O.. I visited the VZW store and the model has option under networks as
1. Global
2. LTE/CDMA
3. GSM/UTMS
Now the Qs are,
1. If this model does have a SIM card slot, how at the first point VZW has lock on it
2. When i asked the VZW associate, he was not sure whether they ever do unlock the device or not
3. If I am ready to pay off complete price of the device which is ~400, what else I would need from them to really 'UNLOCK' it?
4. Is there any means by root/flashing to make such model work for US GSM carriers like H2O or even T-mobile.
Sorry to be so annoying but m new to all these things and quite confused :crying:
many Thx in advance..

Sorry I can't be of more help, I've been on Verizon for 10 years now, but it is by all intents & purposes, fully SIM-unlocked. It's simply unclear as to why some people report problems of using Verizon phones on US GSM carriers. If you really don't want to worry about it & are willing to pay full price, purchase a device through the carrier you want to use it on.
here is the code to choose network
you might need to change the network frequency to gsm if you wanna use it on att or tmobile and when you wanna switch back to verizon choose wcdma try dialing *#*#4636#*#*:good:

I've had people argue with me over this, but the fact is that NO Verizon LTE phone is SIM-locked. None. Nada.
People who claim differently are simply misinformed. (My I545 comes up on AT&T when I plug in my UK SIM and switch to GSM.)
Not to say that all VZ phones are unlocked - my Inc2 had to be unlocked before it would work with that same SIM. If I remember right, it wouldn't connect in the US, either, even after being unlocked. Not so for the GS4.
I appreciate the posts here from people who know. As for me, I am switching to tmobile and will attempt to use this there. If it doesnt work out, I will sell it on swappa and get a nexus 5!
Hi,
Verizon S4 with 4.3 is international unlocked by default.
You just need to select network mode 'GLOBAL'. Then add the right APN.
I am using Indian GSM SIM with the GLOBAL mode selected. All is well for me.
I can provide screenshots if anybody wanna see.
Verizon phones are unlocked out of the box and they DO work fine on US carriers I'm running my Verizon S4 right now on AT&T and I also ran it on tmobile for short time,
even works with Walmart straight talk and Net10 as those are just subsidies of T Mobile and AT&T anyway.
so don't sweat it if you have a verizon phone that uses a sim card, you can run it on any network that uses a SIM card US or international.
baseband issue
Doesn't the MK2 baseband with jb 4.3 block US Sim cards?
Or do I just have a weird s4?

The S4 is supposed to work globally right out of the box, as long as you've called Verizon to enable International roaming on your account. But, used that way, you'll be paying Verizon for International roaming and it's bloody expensive.
The question is, can you remove the SIM and put in a SIM for a local carrier in the foreign country where you are and use the phone on that carrier? That is what being unlocked would allow you to do. Past Verizon phones have not been unlocked to allow this. But, if you called Tech Support and told them you were going to, for example, Europe and wanted to use a local SIM, they would walk you through unlocking (at no charge).
I read a report that the S4 is not locked and that you can use a SIM for a local carrier in Europe, as it comes out of the box. But, I would not trust that. I would call VZW Tech Support and tell them exactly what you want to do - i.e. don't say "can I use my phone in Europe?" The answer to that is yes, you can, at about $1/minute. What you should ask them is, "can I travel to Europe and purchase a SIM from a local carrier and use that in my phone?" If not, they should be able to walk you through unlocking the phone, so you can do that.

to answer your question simply yes.
let's say I take my phone to Spain are somewhere in the UK, I'll go to store buy a SIM card for local network and BAM local phone number in Europe making phone calls, you can even get Data to work if you have that local carrier's APN settings
no unlocking is required because it is not locked.
other companies AT&T, Sprint, t-mobile, yes you have to get The phone sim unlocked.

This is 100% correct. NO LTE phones on verizon are sim locked. They are REQUIRED to keep them unlocked because of their agreement with the FCC for their use of the spectrum they lease. NO OTHER CARRIER must abide by these rules. Only VZW. Sprint I've heard will unlock ANY phone that is capable if you ask them too, and AT&T will NOT unlock any of their phones unless it 2 years old and out of contract (which makes no sense if you have to pay them while under contract anyway). There was a big deal about the Iphone 5 when it came out with LTE for verizon. If you bought a Verizon Iphone, you could put an ATT sim in it and it works, but not an ATT on VZW because ATT keeps them locked.
The Dinc 2 above was NOT an LTE device. Therefore no sim card....and it wouldn't work on most overseas networks anyway as it was a CDMA only phone. I believe VZW tested the limits of the "unlocked" SIM with their first few LTE phones. My Rezound worked with a GSM network sim....but voice and SMS only. It took some unlocking of the bootloader and rooting to run a special Rom to get Data to work on it.
I am heading to the Caribbean in a few weeks, and I will be using a rented SIM card to be able to message back and forth with my wife (with a data based messenger service as data rates are far cheaper than SMS rate there)

I just spent a week in the UK with an ekit.com SIM in my Verizon GS4 - no problem with getting service, no Verizon charge (even though I was on the Vodaphone network for at least some times.)
And the dinc 2, while not LTE, was CDMA/GSM - not just CDMA (yes, the dinc was CDMA-only), so it did accept a SIM card. I'm using that in the GS4 now that it's cut down to micro SIM.
That phone WAS SIM-locked, but VZ happily unlocked it. For the GS4, I didn't have to do anything with VZ to use it off their network.

The phone is already unlocked for SIM and other carriers, all you need is the correct APN for the carrier. I currently have T-Mobile on my i545 and everything works on it.
Can this be done? I ask because I am using the T-Mobile version on AT&T. LTE reception is not bad, it just can be better, especially in low signal areas? Does anyone have any information flashing the G900A modem for T-Mobile? I have searched and can't seem to find anything on this.
Radio and antenna wise, I believe they are the same device specs, so not like a number of years ago where there were antenna differences between them. T-Mobile radio supports all of T-Mobile and AT&T, AT&T radio however only partially supports T-Mobile (NO 4G AWS band, more limited LTE)
There are a number of people that have compared the two variants and no significant reception differences have been found

Right. I understand that. But what I was asking if we could extract the AT&T modem from the G900A (AT&T Branded S5) and flash it on the T-Mobile S5 (G900T). That way the frequencies would be better optimized.
Now my T-Mobile S5 did pick up Band 4 LTE on AT&T and reception was excellent. This is mostly due to the fact that T-Mobile natively uses band 4 for LTE.

I doubt that has any effect at all. Frequencies don't get optimized at least not on your end. I think the phone does have a priority list for which bands to use but it automatically switches when one is better than the other.

I don't know about that. Perhaps it is not "optimizing" but carriers definitely do something to their modems on smartphones to make them work best with their networks. While the T-Mobile S5 works almost flawlessly on AT&T, the AT&T S5 still gets better reception. Perhaps the difference is negligible, but its there.

have you compared both side by side?

I am comparing my signal with the T-Mobile S5 from what I experienced on the AT&T S5. While signal difference in good reception areas is not noticeable, signal in lower reception areas is much weaker. The AT&T S5 would send texts messages almost 95% of the time at my work. With the T-Mobile S5, I am getting about a 10% success rate on text messages being sent.

Yeah that's what I mean. But nonetheless, I still love the phone and this really isn't an issue the majority of the time. Hopefully soon, we can flash an AT&T modem.

The only way I have been able to increase texts going through successfully is by toggling airplane mode. I guess we will have to use that as a work around.
Having an AT&T modem on the Tmobile variant will make the device better handle connecting to LTE/HSPA networks and the phone will switch between frequencies them more efficiently. Now, I don't know if that's possible without bricking the phone.

I think some guy did it with the Note 3. But thing is, the AT&T modem on the S5 has not been extracted.

Extracting the AT&T modem is not a problem I can get it quickly using the stock firmware file. But, still i think it will brick your tmobile s5.

How so? Would it be the same as flashing a T-Mobile modem?

There's your answer right there. T-Mobile released a patch today to deal with poor SMS/MMS or texting issues. Doubt it has anything to do with signal.
Flash the latest T-Mobile update and then see it perform as you'd expect.

Well i was looking to this this with my t mobile s5 with no luck. like another guy said, in good signal areas signal doesnt change but i am in a bad signal area a lot and my phone jst doesnt switch frequecies like it should. I been using att on t mobile phones for a while and installing the att modem but with this one im having some trouble. i have the att modem.bin but when flashing it i get a bootloader response error
You're lucky to get an error and the bin file didn't flash! Please read and search more. There are many threads on xda about similar attempt types. Device-specific modem files cannot and should not be flashed on other devices. They are hardware specific and will cause your phone to stop working if you manage to get it to flash.
Setting up ATT APN settings will suffice for those using att Sim in a sm-g900t.

Yes i realize the risk, and I'm actually not too worried about them. I don't at all think the phone will stop working, however I still can't get the modem on here anyway. I have tried the tar, and bin with no luck. If anybody is willing to put something together I'm willing to test it out. Fortunately in my line of work, it wouldn't be a big deal to get another S5.

I have made all the proper backups. Not to mention I'm not a noob to this, having built a few Roms myself.

If it's not taking in Odin, then I really don't think its going to work. Odin is like the master of all things Samsung for end users. The S5 has a lot of tampering prevention measurements made by Samsung. It wouldn't surprise me if the bootloader is doing a reference check with the modem to see if the modem matches the bootloader.
Also, I wouldn't go about flashing full ATT tar files to the T-Mobile S5. The partition tables are now different in the Galaxy S5 variants when in previous models they were the same. So flashing the ATT full tar could lead to your download mode being wiped.
What exactly is your problem? When you say "not switching frequencies" what exactly do you mean? Like going from LTE to HSPA+ or HSPA+ to LTE etc.
I have created an xposed module for myself that allows me to quickly switch my network preference at ease using a widget. I may share that once I tidy it up a bit. If your issue is being able to switch between HSPA+ LTE 2G etc then the widget should help you. I only use it to force 4G when in a low 4G environment or to force LTE when in low LTE environment.
BTW: What line of work do you do that you can simply get another S5? I'm jealous

Yes I definitely wouldn't go as far as flashing att tar.... And sometimes when I lose signal it takes a heck of a lot longer to gain it back ad t mobile basebands as opposed to art ones. I get another phone about every month and a half to two months so I've definitely tested around on and and also yes when it switches from lte to hspa+ etc it doesn't switch it like any att phone I've had. Takes longer.
And as far as my line of work goes I just mean that I would be able to afford another one if this one broke.

Might be taking longer due to the different radios. Weird though cause if it has an ATT sim and ATT APN configuration, it shouldn't have any delay and function like an ATT phone.
And yeah I'm jealous you can afford a new one if you broke this one takes me a year to save up in order to buy my next upgrade.
