Is this even possible at all? It it's my understanding that AT&T uses GSM, while Verizon uses CDMA. Is this a hardware or a software limitation? I ask because I have a friend willing to trade hits Razr dev for my X2, but I want my unlimited data. Please, someone let me know if out would be worth taking advantage of him.
AT&T uses Sim cards, Verizon does not. In order to use AT&Ts network, the phone would have to have a sim card in it. No Verizon phones will have this. So I dont think it is possible, but Im not a dev. I think the only phones outside of AT&T that are even remotely possible of this is T-Mobile, since they too use sim cards.
I hope I'm understanding what you are asking.

Yep that's what I was looking for. I knew they used sim card, didn't know if there was a workaround for that though. Thank you.

I would think the only possible way to do it is if you were some crazy computer wiz who could take apart the phone and do a hardware mod but even then, I dont know if that would work. Ive heard of Verizon phones being hardware modded to work on sprint. But not AT&T.
Verizon uses sims in their LTE phones. I know. I bought a Razr for my son for Christmas. It definitely has a sim card. I know. I installed it. y

And also global phones have Sim cards, like inc 2
SMILE It's Not Illegal Yet
So I know nothing about the sim card slot and I have a few questions maybe someone can help me understand.
1. Is the slot going to be used by the phone on a day to day basis? meaning does it have to have a sim card in there to use voice or data or both?
2. If the sim card is there for data only, can i use voice from verizon and data from someone else, by lets say inserting a sim card from another company?
2. If I go to china or to Canada (i travel there often for business I live in the US) can I insert and sim card from a gsm carrier and the phone will work? Does it have to be a cdma carrier?
By the way I just got the sprint GS3 for my wife and it has no slot, so im pretty sure I cant use it anywhere but the US without paying crazy overage charges.
You need the Verizon LTE sim card in at all times for data and voice.
thanks for cluttering the developer section

I don't think the Verizon phone was listed as a world phone. Currently no GSM support.
Also, this was the wrong section for this.

Verizon has stated that global capability will be enabled in a future software upgrade. But you know Verizon, I wouldn't hold my breath waiting. :evil:
Have a question while we're on the subject:
What happens if you take your active Verizon LTE sim card and stick it in another compatible Verizon phone? Does it just work, or do you need to activate in any way?
If the sim card fits ie. gnex to siii then it will work.

My GNex still has a sim card in it, I asked for a new sim card with my GS3. Do I just power off the GS3 and do the online Activate My Phone/Switch Phones to use my GNex, say for going to the beach?

No, deactivated SIM cards can never be reactivated. if you want to use your Nexus, you can just physically swap in your active SIM.

Ok so I have an S3 on Verizon with unlimited data on my line. My wife now has my old Thunderbolt and her line is eligible for discount upgrade in January 2013 with the $30 2gb plan. If I upgrade her phone to a Nexus 2 or whatever is out, activate it with her new sim card, can I then just swap sims so I get the new phone and keep unlimited on my line?
This way I still get discounted upgrades and she gets my old phone.

Yes. I just gave my girlfriend my Nexus for use on her unlimited line. You just have to go into the store and get a SIM for it.

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.
I called tracfone to activate a Verizon galaxy s4 I got from a friend who switched att and iphone 5. When tech support tried to activate it they said the phone was locked and I needed to have Verizon unlock the phone.
I cannot get a hold of my friend as he's on a business trip for a week. Is there a way to unlock this myself? or can I only have Verizon do this. And if I can do this myself, will I have quirky setup and need workarounds for use?
My galaxy has a verizon sim card and a 32gb data card. My phone model number is i545 if iirc.
Thanks for any advice.

To help you get started with replies quicker I'll say that it is mostly dependant on which firmware you have and also if you have root.
those two factors will allow you to know if you can use any of the unlocking apps by chainVire if they are still around. someone will point it out to you I hope. On the go, can't show you myself. Best of everything in your efforts but read around. I'm sure someone has done it before. Welcome to XDA. I seen that was your 1st Post. Awesome!
That app is for unlocking the sim card. My track phone doesn't need a sim card.
Can I maybe just remove the sim card and have it work? Or do I need the sim card for the s4 to work at all?
Idk why they told you it is locked, all Verizon phones legally have to be carrier unlocked because of their deal with the FCC.
Translated from Calligraphy
Okay, I also remember they asking for an MEID off my S4 and this one only has an IMEI number.
Will this make it not compatible? I don't want to pay to unlock this thing if it won't work with Tracfone afterwards.
I read a few threads and am confused, so I thought I would just ask. I have a few 4G LTE devices for Verizon and am ready to switch to AT&T. Let's just say that Verizon and I had an argument and it is time to switch. Plus I would be saving over $50 to switch to AT&T with a month to month with a BYOP plan.
I visited the AT&T store today and had them insert a SIM into my S4. I get the error "This SIM card is from an unknown source" in the banner. I get a signal strength and a H for where the data symbol 4GLTE is. Then it drops the signal and refuses to have a data connection. At this time the APN settings were NOT adjusted. This was a straight out of the box S4 rooted on NC5 with Android version 4.4.2. After messing with the S4 for awhile he moved to the S3 and entered the proper APN settings. It pulled data, but only at EDGE speeds or 1X. Also, my last device, a Samsung Galaxy Tab 2, has no way of editing the APN settings. It is NOT rooted and is still on stock firmware.
My questions are these:
1. Can this be done?
2. What do I need to do to the phone(s)/tablet to make it work?
3. Will I be able to get 4G speeds?
I do not want to purchase phones with AT&T today because I just don't have the money. I already have these devices, I just want to swap them over. I am comfortable with flashing using ODIN and even so far as using safe-strap. I have flashed some custom roms, but my phone is a daily grind phone and I really want something that works 90% of the time.
Thanks in advance for any help!

That thread just asks if the SIM card would work and if they would need to flash a GSM ROM to their S4. That thread does not answer the questions I asked. I just gave my insight after a visit with the AT&T store. Store techs tend to not know as much as the XDA community. That is why I asked here. So no, it is not a redundant thread. I appreciate your answer, but it isn't what I am looking for. Not a straight up yes or no, this or that.
As for the GSM locks I discussed, it was from an experience I had with a Motorola Droid 2 and using it on a local GSM provider in the USA. So yes, that was pre LTE.

Yes, you can install an AT&T SIM, set up the APN, and it will work. What bands you get and what bandwidth you get depends on what bands AT&T are using in your area. You won't likely be able to get LTE speed; most likely just Edge. You can't fix that, as it's a limitation of the phone's radio hardware. Again, some people have made claims that you can flash the AT&T GS4 modem on a Verizon phone and change that, but that's pretty risky as it will likely brick your phone.
2. What do I need to do to the phone(s)/tablet to make it work?
It works, for some level of "work". If you're stock,some people have reported that the firmware requires CDMA for some functions, like SMS. I haven't verified that. I was able to send SMS with my phone and a UK SIM which uses the AT&T network.
3. Will I be able to get 4G speeds?
Not likely. For example, see here http://phandroid.com/2012/12/10/nexus-4-att-lte/ - the common band, LTE Band 4, has limited AT&T coverage.
I haven't gone over the specs of the two phones lately to match them up, so that may be worth looking at again.

Thank you for your answer. I decided to trade the phones into AT&T and get a credit towards a Samsung S4 and a Asus Padphone X. After I read a few more posts over the internet and a few more hours figuring out how LTE works I came across the answer. I did miss what you meant and I apologize. Again, thank you for your answer.
