newb questions about sim card swapping - T-Mobile Samsung Galaxy S 5

absolute beginner here with some questions. first, if i have a smg-900t unlocked, can i put a boost mobile sim in and expect it to work, provided my apn settings are right? i keep getting not registered with network with either a boost or verizon sim. i know you used to be able to just swap sims back in the day and your phone was working. the people at boost say you cant do that with their service, is this right? thanks for any help.

A phone that you want to use on boost (sprint) or verizon has to already be in their system for the phone to be registered. Thats how CDMA phones work.
GSM like the ones on T-mobile or ATT or unlocked dont have to be. These are the phones that can have their sims swapped and just work.
Having a unlocked T-mobile phone on Boost is not going to work. Sprint doesnt allow that anyways.

could someone please help me on this. i know it can be done i just dont know how.
thanks in advance.
Technically speaking, you should be able to go into any sprint store and purchase a boost starter kit. This only includes the SIM card. This is kinda a hit or miss situation because we are not allowed to open or manipulate any boost accounts at the store. Once you activate the SIM card, you should be able to connect it into any GSM/IDEN phone and use it as a boost phone. I know we've had several of our NEXTEL phones used on boost. Just understand that it obviously would not have the direct connect radio.
i dont think that i can use a iden sim in a gsm phone. nextel phones are iden. anybody else have any info on activating an alltel phone on boost?
To the best of my knowledge CDMA handsets can't be unlocked from a carrier the way an iDen or GSM handset can. In fact the carrier can tell weather or not an ESN is from their handset. I know Sprint cannot activate my dad's Alltel RAZR V3m despite the fact that Sprint offered the exact same handset.
The only way you're going to get a Touch Pro on an unlimited plan is to sell your Alltel Touch Pro and buy a Sprint one. Sprint will not activate a boost phone on sprint and vice versa.
now i am trying to get this same phone activated on cricket. had anybody done this before?

[Q] Unlock Verizon Samsung Galaxy S4

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.

Verizon to AT&T?

I'm on AT&T,but just bought a rooted S4 off someone with a Verizon ROM on it. Would I just need to flash a AT&T ROM for the S4 to be able to get the SIM card to work with AT&T?
Any help appreciated.
Same here. My friend gave me his S4 today and it is Verizon and running on the stock ROM. However, I am on AT&T. From what I hear this phone comes factory unlocked so you just plug in the SIM and it should be okay. Is there anything else that I need to know if I want to use this phone as my main?

After a brief visit with AT&T today, they installed a SIM card from their carrier into my phone, but it would not get speeds grater than EDGE at the time. 3G may have been possible, but it didn't see it right away. Also, they had to update the APN settings in the Settings -> More settings -> Mobile networks -> Access Point Names. Lastly, after searching the internet, Verizon carrier locks the GSM in the states. In other words, they make it so you can use GSM OUTSIDE the US but not allow AT&T or T-Mobile SIMS to be used in their devices. This is a carrier lock, not SIM lock, so they can get around the whole "well, our phones are sold SIM unlocked" bs. After calling a level two tech support, he told me that there is no such thing as a carrier lock or SIM lock, and he could not give me a code. The phone was able to make a voice call and send a normal text, but data sucked.

Sorry to disagree, but my SCH-i545 works on the AT&T network with an AT&T SIM installed.
I only get Edge because that's the only band that VZ and AT&T has in common in this area. Swapping out a SIM isn't going to fix that.
What you're finding about GSM locks applies to pre-LTE phones. The LTE phones are not SIM locked, aren't carrier locked. Period.

Q::: Is there anyone already running a VZW CDMA sim card on a T-mobile note 4??

I still have my Vzw note 2 and can run GSM or CDMA sim cards and have test and used it.
With the Bootloader unlocked and right ROM and change the Apn Settings.
But with the note 4 the ROMs are not made for multiple carriers anymore.
AT&T will work on here and I still had to updated APN settings a little.
I removed all others to keep it form dropping call because its jumping around to other settings.
Also turned off Lte so data will stay locked in on H and H+.
I have seen it drop data connection jumping back and forth form H,H+ and Lte.
When i place my wife VZW sim card in my Tmobile note 4 LTE kicks in and I can use it.
Signal jump on but will not connect to make a call and texting will not work.
Q::: Is there anyone already running a VZW CDMA sim card on a T-mobile note 4??
Q::: Will a sim card unlock work??
Q::: What unlocking site did use??
LTE should theoretically work, but you still would not be able to call or text because most places still rely on CDMA for the talk, text, and 3g. The Tmobile phones do not have the hardware to support it. Plus any time you would not have an LTE service, you would be out of luck since there would be nothing available for the phone to fall back to. You would also run into trouble if you needed to register the phone with VZW for any type of service as the IMEI won't be in their database and they won't allow any phones that aren't there to be officially registered with them. Not to mention other problems like being unable to update PRLs and profiles.

Need Advice - MSL Programming Instructions

I had a question, if someone could shed some light on this, it would be very much appreciated! Recently, i obtained my MSL from sprint, and was wondering if i could, for the purpose of better data packages, switch to boost mobile by reprogramming the cdma radio. Its funny, because the first time i called to ask them this question, they told me i could not get the unlock code unless i was with them for a year, but funny enough, i called them back and told them i needed it for development purposes, and they gave it to me! Back to the original question, though, i would really appreciate it, if someone could point me to a relevant tutorial or something like that. Thanks for taking the time to read this!
I was told by sprint tech support online that I'd need to insert a non-sprint SIM to trigger the device to request the MSL unlock dialog. No idea if that's true, but it is consistent with how I unlocked an ATT BB pearl for use on T-Mo back in the day. I tried with both an active and inactive ATT nano SIMs in an adapter, but got a no SIM inserted notification. Not sure if that was due to the adapter/sim combo making poor contact, or if the device is not going to play nice with domestic GSM SIMs. Haven't gotten my hands on any non-sprint CDMA carrier SIMs yet.

I have a straight talk, and boost sim, both were active at one time. I wonder how to trigger that menu? I have my msl code.
