Flashing AT&T over Verizon; possible? - Motorola Droid X2

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

LTE sim cards?

Ok, so I'm totally used to CDMA, obviously, but I've lived abroad and appreciated the beauty of just swapping SIM cards in when you're in a new country.
Is it possible to just swap SIM cards like GSM cards, or do you still have to call Verizon to activate? The reason I ask is, my father and I were going to swap Thunderbolts, but I didn't have time to call Verizon and do the ESN swap thing. Could we just have swapped SIM cards?
SIm card
SIM cards are for GSM technologies.... Verizon LTE is a GSM tech... And yes thats the theory, with Verizon announcing some day you will be able to use other networks LTE SIM cards in VZW phones. Sim card in your fathers phone gives you access to his google account and contacts.. unless you have transferred all google contacts to your SIM card.
It will only work with the sim you are given for the TB.

Got it. So the SIM is tied to the ESN somehow? Either way, they don't work like GSM sims.
they would most likely if the phone were entirely gsm, but since it's not. Like if you ruin the one you have, the only way to get a new one is directly from verizon and they can only be activated for the phone they are first put into.
dude no one here knows what they are talking about. if you swap sims with your dads phone then it should work fine. the phones will activiate with the respective phone number tied to your sim card. that is how you activate a replacement device as well. i just took my sim from my old phone and put it in the new phone and that is it. works JUST like GSM

If that was true, I wouldnt have to replace my SIM card both of the times Ive sent my phone in for repairs. My service is still on, just switched to a different phone. The verizon rep I spoke with yesterday(One of the few that actually know what she was talking about) confirmed that the moment that a phone gets disconnected the sim card gets retired. I dont know why, and I dont understand it, but thats the way VZW is rolling with it for now. As long as I dont have to pay for it, IDC. lol.

that must be because whoever is disconnecting the phone is killing the sim also for some reason. i have used the same SIM card in 2 thunderbolts and a samsung charge.

That's just it. That rep doesn't know what they're talking about. If you get a replacement TB, nothing should be changed on the account - no phone gets "disconnected." You simply move the SIM to the new phone. Sounds like that rep thinks it should be like a CDMA phone, where the account is changed to reflect that the phone's ESN has been changed when swapping phones.

Did you activate an old phone while waiting for repairs? That's really the only way your SIM would be deactivated.

I did. Im still unsure of why they retire my sim though. All in order to send me another one that will sit here till my phone gets back. Why not just put it on hold or put it on temporary hold?
Sim cards work in any phone that will take them.
Just to put this one to bed--they work just like GSM SIM cards. I swapped my SIM between another Thunderbolt and a Charge, and it worked perfectly every single time.

Where can I buy a sim card for a Photon

I just purchased a used Photon 4G. The phone works great but it did not come with the sim card. I would like to be able to use it overseas so I need the sim card. I went to my Sprint store and they told me they do not sell the sim cards.... I talked to Motorola and they told me to talk to Sprint... There are sim cards on the Internet, but I have no idea if they will work with the Photon. So.... Where can I buy the OE sim card for my Photon?
It's an unlocked sim port, so any provider sim will work, but keep in mind that at&t & t-mobile frequencies are blocked from being seen by the radio. Hopefully a dev will be able to rewrite the radio to pick them up.
So this one will work?

So would this card work if, (when), I take my phone out of the country?
What are you trying to do? If you want to use the phone out of the USA for voice/data or mixed for inexpensive..Then purchase a pay as you go number and Sim in the country. If you want to use your USA number for very expensive then use that card.
Very simple.

Confused, I have Samsung galaxy Axiom and....

it is from us cellular if you ask me its the s3 mini anyways itsa cdma phone that has a sim slot which has a card in it for us ceullar. now im confused the phone specs say its cdma only but with a sim card that makes me t hink its gsm global(locked to any us gsm providers im sure) and cdma so I would assume it will work with say cricket wireless.
I am leaving u ceulluar and would like to use the phone with c ricket wireless and being its a cdma phone im surei could it is just that sim card confused me.
I know on phone in past cricket can take your imei i think it is and use a tool over the phone to convert it to propperly work on their network.
So basically anyone know if this phone can be used with cricket? is it locked? do I ahve to flash it. if the gsm part is locked that wont matter since i will only be ising the cdma part. here is the link to the phone on us cellular

Edited: The sim card has your programing for CDMA & 4g/LTE access. Just took mine out and it has zero service without it. I would guess as long as you put it in another compatible phone you would get service.
Hoping someone will figure out a simple rooting method, but doesn't appear there is a lot of interest yet.

Thanks but nah not what I was wanting, i wanted to be able to use the phone on cricket but since they dont use sim cards since their phones are cdma was why I was confused that this one has a card since usually only GSM phones use those. so im guessing I wont be able to use it on their network if they added it..I know they can convert certain imei's over the phone with a tool they ahve with cricket support but have not tried that yet.

So, just wondering, would the Samsung Axiom work on T-Mobile or AT&T ?
yes and no
The R830 by U.S cellular is a CDMA phone. now ah days having a sim card slot does not symply mean its GSM ....TMobile....GSM ALL DAY. ATT GSM all day. Vzw,sprint, uscellular...CDMA. the Sim card in question is a 4glite. it controls the 4g side and basically activates the phone upon new activation. the question is: WELL THIS PHONE WORK ON CRICKET? Answer...yes...I put one on Pageplus by just activatiing the imei and then OTA...but I'm having trouble with the DAta side... cant get data or MMS (picture messaging) to work..talk and texts works fine.....Now im on to figuring out how to get this thing into DiagMode without rooting it Oh yeah.....try activating your Imei on cricket and then star code it. . if it asks you to press 1 or 2 but you dont see a keyboard,....thats okay...just let the lady run her mouth until the music starts playing....when its done the phone will restart and you'll have talk and text

No, your phone will not work on either. The sim slot in question is for 4glte, all 4g phones will have this sim slot. A GSM sim will not provide any functionality at all.

[Q] verizon galaxy s4 on other network?

If I were to buy the galaxy s4 for verizon and end up changing carriers in the next couple months, would I be able to use the phone on a network like at&t or tmobile? I know that in past phones, this wouldn't have worked since they have never used sim cards, but now that theres a sim card for lte, would it work if I put whatever carriers sim card in the verizon s4? This is kind of a long-shot I'm guessing, but just wanted to see if this is possible.

I see no reason why that wouldn't work. Although I'm sure Verizon could come up with some way to screw you over.

The presence of a Sim card doors not mean it's compatible. It is the presence of hardware GSM radios that makes it compatible.

[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:

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?

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)

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.

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

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 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.
