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

I'm a VZW customer and I work at T-Mobile. I've tried popping in my manager's T-Mobile micro sim-card into my VZW S4. The voice service worked flawlessly but there was neither 3G nor 4G connectivity. No idea why.

Did you change the APN's?
T-Mobile is NOT GSM. The only way would be change the apn settings to see if it will 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.

Yes it is possible. And it is actually not that much work.
#1 be rooted
#2 put in tmobile sim and restart phone (cant change apn with vzw sim)
#3 change the apn settings for voice and data to t mobile (google it)
I have been using a verizon i545 S4 on tmobile for 3 weeks now. I have voice text and 4g h+ data.
The S4 is global, even if verizon tries to lock it down.

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 think this deserves a thread on its own and this shouldn't be closed because there are a lot of different ways this can go and a lot of different ideas behind using this effectively.
I was unhappy about the amount of money Verizon charged per month so I decided to end my contract and use my Note 2 on T-Mobile. Unfortunately, "T-Mobile" Note 2's are rather hard to come by so I stuck with the Verizon one and decided to unlock it. My question is:
For people using the Verizon Note 2 on other 'contract free' plans in the US:
1) Which rom works for you?
2) Did you modify settings to get data to work properly?
3) Which plan did you choose and how do you like it?
I'll start:
1) I'm using Tweaked. Out of the box, it works with T-Mobile SIM card and receives data as well. In San Diego I get HSPA+ most of the time, even indoors, so the rom works pretty well with different carriers. I did use the Verizon Tweaked rom as well.
2) It wasn't necessary. With the stock rom I wasn't able to consistently get data. I wasn't even able to get Edge to work properly. With Tweaked, I didn't have to modify the MMS settings so I can even send picture messages without issue.
3) I'm using the T-Mobile $30 plan with Wal-Mart. I get 100 minutes a month, 5GB of 4G data and unlimited text messages. Contrary to popular belief, text messages do not eat up my minutes. I send more than 50 text messages per day and I still have about 20 minutes left before my recharge and I'm about 3 weeks into this month.

i just bought a verizon note 2 today for my at&t plan... i put my sim in and i had voice and text instantly. changed the APN and had hspa+ data.. didnt even need to root it to change the apn like i had read on another site. never knew these phones were unlocked out the box from verizon. is LTE possible im wandering with at&T? maybe with a new radio?? even so im fine with 4g, LTE would just be a plus.
Some tmobile users have had problems... I hope somebody can help those users out.
Hi Everyone,
I've been getting the shaft from Verizon with the Galaxy note 2 and paying the 200+ month bill as well. Anyone out there switch over to Page Plus, I've read that they piggy back off of Verizon's network. Any experience ? Thanks
Im curious about this as well, looking to move to tmobile with my note 2 until something else comes along.

Took my rooted verizon note 2 running alliance rom into a tmobile store today. I borrowed a sim card and booted up. It showed signal, but wouldnt recognize it. I switched to global mode in mobile networks and ran apn global fix and it showed h+, h, and 3g. Data was functional as was wifi. Should it show 4g or LTE as well?

Tmobile 4g is h+ they are rolling out lte oz certain areas but without proper radios the Verizon note 2 will not get their lte and I don't suggest flashing another carriers radios. So hspa+ would be the best you could get.

It works pretty well, WHEN it works. Some roms are stubborn about sticking to Verizon and don't allow the switch. I was using Tweaked and it worked well. Tried out LiquidSmooth and couldn't get cell signal at all. Even with global mode.
Now I'm gonna try out Alliance because I want something more current.

I have my verizon note 2 flashed to pageplus have great service... everywhere that verizon has service my phone has service.. I only have 3g though . No 4g lte available for page+ yet... call sms mms and data all work.. im running jellybean latest rom
I used my Note 2 in Europe over the last week without many issues. Data was fine and worked well when I used it. Used SFR in France, Vodaphone in Spain, and T-Mobile in the UK. When switching between carriers, first connection to the network took a little bit, but beat out the new wife's SGS4 when connecting to the networks. When I got back to the US, my phone decided to refresh SIM data, but haven't had any issues other than that.
I'm in the process of trying to find an AOSP or 4.3 CM based rom that can use T-Mobile. All I've had luck with so far are TW based roms. As soon as I switch to a CM based rom, I'm not able to make or receive calls and apn settings can't seem to get data to stick.

Just wanted to update some experience:
AllianceROM :
1/5
Just not a very pleasurable experience. Data worked and calls worked fine but I experienced a lot of bugs just in relation to the rom itself. Re-flashes didn't help. Whenever I opened a picture in Gallery it tried to use this Accuweather overlay on the picture, would always crash gallery. GPS wouldn't work properly either. It was always stuck and GPS fix never seemed to do any good.
Pac-Man:

I want this rom to work really badly. Out of all the roms I've tried, it's the cleanest, fastest and picked up T-Mobile data just fine. Unfortunately it will not send SMS. I tried changing to global mode, GSM mode. 4G worked, 3G worked, data worked and even PHONE CALLS worked. But for some reason even after flashing again, rebooting, reinserting my SIM card, I could never get SMS messages to work. It has the correct MMS info but that's not the issue. It just will not send SMS.
At this point in time, the most consistent and best rom I used was Tweaked but I wanted to try out AOSP after the Nexus 5 came out and I missed the plain Android. I also get annoyed of the Galaxy excessive amount of 'hint' pop ups during initial flashing.
Just switched to net10 and it's not too bad. Data is a Lil slower but not much. Just popped in the sim and added apn info. Running beans 22.

Straight Talk just shut off the data on my VZN Note 2
I've been using my Verizon Samsung Galaxy Note 2 on Straight Talk for several months without any problem. I did the Bring Your Own Phone thing just as they advertised. I never had any problem until 2 days ago when they shut off my data. When I called them, they said my phone and ALL Verizon phones were not compatible with S.T.
I asked why I was able to use it just fine and then all of a sudden they nixed my data. Not the voice or text. Just the data. They only repeated the same prewritten jargon about Verizon phones not being compatible with Straight Talk.
Does anyone have any suggestions?

After happily using my 'old' S4 on T-Mobile with HSPA+ since having the Note 3 as my primary line, I was naturally excited to update the baseband and unlock Band 4 LTE. However I noticed some caveats which I've now solved which will undoubtedly confuse everyone at some point.
Assuming you've got the correct APN for T-Mo (fast.t-mobile.com) and naturally install the SIM, if your phone is on global you will happily see working LTE but not so fast (no pun intended). If you call or text, it fails. If you quick check your About -Status in settings and look under network it will say say Unknown and not T-Mobile. Why? Essentially you're in LTE data only mode because by default the baseband is looking to connect to CDMA for everything else in the CDMA/LTE marriage that is Verizon unique, which obviously won't work here. The assumption otherwise is that you will only need GSM if traveling internationally so it never looks for LTE with GSM.
The quick easy fix is to drop out of Global back to the GSM/UMTS setting, which will bring everything back, network restored to T-Mobile, but now it won't use LTE again, lame.
Luckily there is a fix. Use the PhoneInfo app or however you prefer to get to the Testing App. Under device information change the dropdown to LTE/GSM (auto PRL). Toggle airplane mode or restart. When it comes up you should be on LTE and quick check settings again you'll see T-Mobile, and everything will work. So far this seems to hold pretty well.
EDIT: Note: This works for TW Roms. I have not had success in CM10.2. In CM I've only gotten LTE data (wrongly labeled Verizon) and nothing else. Doesn't even pick up my phone number regardless of settings used.

I am using this app and it is great. When it works, it would show T-Mobile as Net. Op instead of Unknown. Only issue I am seeing is that 4G LTE signal is not so great over where I am at and once in a while it would drop to H+ and then get back to LTE. During that cycle, the Net. Op would become Unknown again. Wish there was a way to fix this permanently like tricky the SMS app to send GSM or whatever it is causing Net Ops to be unknown.

Couple of things. Remember as I started with the baseband in i545 when on LTE really wants to use CDMA as the default so when it's searching it's not going to obtain GSM as instantaneous As it otherwise would. Don't see any specific way of that getting patched ever as we're going against the grain of how it's typically supposed to be used. If you are on a fringy area for it, you may be better off just leaving LTE off, H+ speeds are practically the same anyway. Tmo is only using 3-5mhz channels for band 4 as they use other channels too so for us it's not going to be superfast like Verizon on average anyway.
My phone is in Global mode, I have fast LTE internet and calls/texting works just fine. I am using a Verizon S4 with MJ7 and a T-Mobile simcard. No need to change anything except the APN and switch to Global.

so using the 4.4 gummy rom you were able to connect to LTE / HSPA+ networks easily? And SMS / MMS worked just fine? Upon trying with the MJ7 update, non-rooted, I could only connect to Edge services under the GSM profile. Using global would barely warrant the HSPA band.

Are you actually getting "LTE" or reframed 4G?
please school me how to change apn.
well let me give you a trick, flash an i9505 rom which you can find them here http://forum.xda-developers.com/galaxy-s4/i9505-develop
then flash any verizon kernel (because if you just flash an at&t or t-mob rom it wont reboot it will say triangle and not authorized verizon software)
dont forget to update your baseband to lastest then you can enjoy LTE (and fast) without any problems.
if you get and prop. issues while flashing international roms just change the "updater-script" first line to :
assert(getprop("ro.product.device") == "jfltevzw" || getprop("ro.build.product") == "jfltevzw"
then you can flash anything you want.
Here is how I did it
Here is how I did it, but needs some minor updates since then. Please let me know if anyone tries it and is happy with the result.

I have a Verizon Galaxy S4 rooted and running the Darthstalker S4 Rom. I recently got an ATT sim card to put into my device because they were second best with the signal where I live. Which is the US. What I want to know, Is there a way to get 4G or 4G LTE on my device with ATT? I know 4G is here because my cousin is with them and has 4G LTE. Ive tried a few APN settings to no avail. Also every once in awhile I completely lose service because it starts searching for a service to run on again. All I get is H or H+ and half of the time, I dont even get that. That data never really works on that. Especially H. Also, I never get 3G either. Sorry if this is long, Im just at an end where I cannot find an answer. Any help would be greatly appreciated. Thanks

Try flashing the latest Modem, it seems to to support the ATT LTE Bands. I have used an AIO sim in both a VZW GS4 and LG G2 and both get LTE. It doesn't seem to switch very quickly either. Also make sure you are have LTE/GSM selected for the radio.
My 2 cents

Could you point me into the right direction? Also, I can only choose GSM, or LTE. Not both at the same time. And GSM only works

Kinda dependent on the ROM but you might want to use the APP called Advanced Signal Status (Play Store).
From memory you can't since this model dosent support the other carrier's LTE/4g band. May be wrong but pretty sure that info is correct

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.
