Hi
I have a carrier unlocked T-Mobile s8+ and need to use a Verizon SIM in it and am getting errors trying to use a verizon SIM. The Verizon SIM is from another phone and is already registered. I put the IMEI number of the phone into Verizons web portal to test compatibility and it failed. Does that mean there is no way to get this combination to work? Does the IMEI need to be in the VZW database for this to work? Will flashing XAA guarantee this to work? Thanks for any help and advice.

do u have a tmobile phone, it is different than the carrier unlocked phone, those are 2 different models,
the carrier unlocked.. the sim is unlocked..
the tmobile is not carrier unlocked, and by flashing the firmware of the unlocked version, will NOT unlock the sim.. u will need to device unlock app with the tmobile phone 1st... and usually tmobile will NOT unlock unless u have paid it off and using on their system for 40 days..
others like me had it unlocked with days of service, cause we are tmobile customers for years already... I on the other hand bought the phone on ebay from someone who bought it from Samsung and the imei was not added to tmobile system and I had to call tmobile to add the imei which took about 3 days, then to call back to request the sim unlock which took another 3 days, the device unlock app unlocked the phone instantly...
that was my process for me to get the sim unlock... but if urs it not unlocked and is paid off, another way to get it unlocked it to give it to someone u know, let them use it and call tmobile to start the above process...
Hope that sums up what must be done...

Hi thanks for the explanation, I am pretty familiar with the differences between carrier (SIM) unlock and unlocked firmware as I have flashed Android in the past. I had the phone carrier (SIM) unlocked by T-Mobile through their app and I was still not able to use the Verizon SIM in my phone (not registered error). It turns out (and I found this out by reading through the many messages in this forum) that T-Mobile firmware apparently disables some frequencies that other carriers may use. Once I flashed the XAA unlocked *firmware*, I popped in my Verizon SIM and it worked like a charm. I hope this info is useful to someone at some time and I thank all of you for your contributions to getting this working. KUDOS!

Good to know, but sound weird, thought T-Mobile phones work for all gsm Sims just needing to change apn,
But now cdma merging with gsm, that's so much better as far as phones go, use any phone now from any provider.
Look how the s8 plus is all the same software and the same hardware, just different carrier stuff..

I thought it was weird too. Busted my head for a couple of days trying to figure it out. Is Verizon still CDMA? *scratches head*
Yes, their 3g and 2g networks are CDMA.
If you insert Verizon sim into T-mobile phone, you'll get LTE data, but you won't be able to make calls. Only data will work. T-mobile firmware support band 2, 4 and 13, so you should have data, but not phone service. If you don't have data icon, you'll need add Verizon apn.
FYI
Flashing the phone with G955U1 firmware fixed this issue. I am now able to use this successfully on Verizon.

So I have an HTC Touch Pro 2 with Sprint and I was wondering if it was unlocked. Is there a way to tell? Is there a way to unlock it?

What specific function are you trying to unlock? There is an application unlock in the "themes and apps" subforum for the Rodium. It is on the 2nd or 3rd post of the stickied "software worth installing" thread. This will allow you to run unsigned applications and such. If you mean unlock the sim card, there may be a cab for that... but I haven't looked into it.
Yes, you need to clarify. So you mean SIM unlocked?
The Sprint TP2 is unlocked for use with GSM SIM cards overseas, but you need to flash a new radio in order to use a ATT or T-Mobile SIM.
Thank you everybody for the replies.
Sorry that I was unclear before. What I meant is I would like to run the phone on ATT or T-Mobile after buying the phone from Sprint. There's a sim card in the phone but there must be something else I have to do, right?
Edit: Actually, there isn't a sim card in the phone. I don't think the phone had one when I bought it. Do I need to get one?
Umm, yeah. You need a ATT or TMob SIM card in order to get service from those carriers. But it will work on Sprint without a SIM, CDMA uses a different chip, not SIM, which is embedded on the phone's motherboard.
Also, you will need to SIM unlock the phone for it to work on ATT or TMob.
http://forum.xda-developers.com/showthread.php?t=578659
The Sprint version of the phone is unlocked to work abroad with foreign SIMs, but you need to unlock it to work on ATT or TMob.
I'm not speaking from experience here, just reading the info available. Go to the CDMA subforum for Rhodium for (lots) more info.

Hi my name is Adam and I represent Sprint as their SprintCareGuide. We recommend that you do not unlock your Sprint phone. If you do , you will lose the warrenty and we will be unable to help you with any issues you may have down the road.
Hi All,
Does anyone know if I can use my rooted SGS2 over in Europe? Specifically I'm using a rooted T989 running TDJ's Darkside Evolution 3 v7 with the venom kernel and the Touch0Color theme. I'm going to the Netherlands, where I think I can just get a local Tmobile (NL) sim and be fine, and the Romania, where I believe the phone will work on the Orange network.
Since the phone is rooted, it should also be unlocked, so there shouldn't be a hitch in just switching the sim and being up and running, correct?
Any thoughts, and especially first hand experience, would be appreciated.
I just want to make sure I'm not missing something completely obvious that makes simply buying the cheap $15 throw away the better option.
Thanks,
That's correct. Just call tmo for the unlock code...tell them the truth-you're going overseas. When you get there get a local SIM and pop it in.
Sent from my SGH-T989 using xda app-developers app
your phone should work in with any gsm carrier to make phone calls but your phone has to be unlocked. I dont know how the data will work since most gms carriers frequency bands are different from Tmobile's.
Ok, so I went to T-Mobile as instructed, and they said they would get back to me in 14 days (I know, right?). So they just sent me the below.
What should I do? I'm still wondering if the phone is just blanket unlocked as a result of the root and the new rom, but I'd prefer not to go buy a prepaid AT&T sim to find out. Can anyone out there advise?
Here's what T-Mobile sent me.
BEGIN
T-Mobile Phone #: 5********9
T-Mobile Sim Unlock Request
Sim Unlock Reference: 5*****6
IMEI: 3*************0
Thank you for taking the time to contact T-Mobile. Unfortunately, we are unable to provide the unlock code at this time. After review of the account we have determined that the device is not in use with the corresponding mobile number. T-Mobile policies and procedures state that the device must be in use on the mobile number requesting the unlock code. If this is a new device please allow 3-4 business days prior to submitting a new request to allow your usage to update in our system.
Thank you,
SIM Unlock Department
Thank You,

I checked the numbers twice, and they are correct. But, obviously, I'm using the number with the phone on t-mobile without a hitch ...
So I called T-mobile, and asked what's what. They said that they couldn't even see what my phone was on the system, and then suggested that I call Samsung. Samsung said that they couldn't verify ownership of the phone and said to call tmobile. So I'm wondering what's going on here. The tmobile rep did say that she doesn't think that I'd be able to use an AT&T sim even though I rooted my phone. How would they know though, isn't the normal android stuff unlocked?
Any thoughts?
"rooted" and "unlocked" are not same terms.
I have rooted my phone and requested Unlock code from t-mobile before my trip to russia. Their policies state that you have to be t-mobile's customer for at least 40 days.(though because of circumstances they gave it to me on 39th day)
In russia I bought local sim card, slip it in my S2, followed an instructions provided by t-mobile and had no problems to place/receive calls and use an Internet. Though speed was 3G.
First, Rooted it doesn't mean Unlocked! They are 2 different operations.
You can be Rooted but NOT Unlocked, you can be Unlocked but NOT Rooted
and you can be Rooted AND Unlocked.
That being said, I beleive you have to be on Stock ROM when you
request the unlock code. With a custom ROM they don't recognize
your phone.....
If you don't want to flash back to stock until you get the code, then I would
go to a local cell phone store (not a company, just a local that sells
phones for all major carriers) and ask them to unlock it for you.
It should take about 5 min. and should cost about $20.
You can also go in Romania and unlock it there for about $5.
I know nothing about Netherlands, but it should be the same.....
Good luck and have a nice vacation.
I've had my S3 about 5 months, I bought it retail from ebay from a seller that didn't unlock it, it is still tied to AT&T. I use Straight Talk as my service as at&t or T-moblie will work with out unlocking them. I want to unlock my phone now and have a question.
Beings that the micro sim in my phone is straight talk and is working, how do I unlock my phone? from what I've read about unlocking, you need to have a NON-WORKING sim to be able to unlock it. Or is there a way to unlock it with out a sim in it?
thanks for your time.
You actually need a Sim that is not att, to unlock. You will need the unlock code from att or you can buy them on the internet. I was able to get my unlock code for my S2 from att. You have to have the phone on their service for at least 6 months, you call them say you are going out of the county for a few weeks, and bam!, they give you the unlock code.
Once you have the code, you need to put in an activated sim from another provider other than att, when you turn the phone on you'll be asked to enter unlock code. Enter the code, hit enter, bam unlocked.
This won't work with a sim that is not active.
So if you have a straight talk sim in, and have for six months, and its working, and its a i747, then I think you have a unlocked phone.
Sent from my SAMSUNG-SGH-I747 using xda premium
just to clarify, you do NOT have to have AT&T for any given amount of time before you receive an unlock code.
i was an AT&T customer for all of 10 days and got my unlock code for my Galaxy S3. it is VERY dependent on the agent you speak to for asking for an unlock code.
anyways, since you are using Straight Talk, you should have an unlocked phone. best way to test is try to put a different SIM card in it and see what happens.
I was told my device was "ineligible" to be unlocked. AT&T sucks.
If you don't want to waste time talking to a rep that may or may not help you, use this method, it's easy and free: http://forum.xda-developers.com/showthread.php?t=2014982 (it's for the Note II but it works on the AT&T S3). You don't need a non-working sim for this method to work, but you won't know if it worked until you put in a non-working sim.
Also, you'll likely only get Edge network on T-Mobile unless you happen to be one of the lucky few in an areas where you can get 3G or H+.
But as posted in other threads, if you're going to call AT&T, call their International Support line: 1-800-335-4685 (found here: http://forum.xda-developers.com/showthread.php?t=1962453&page=16 )

Thanks for all the great info, I'll give these a try.
Purchased from T-Mobile a year ago, all paid off, and permanently SIM unlocked by T-Mobile app (white-listed by T-Mobile so it would unlock). So, the phone is free and clear. I think the answer may be self-evident in the model numbrer, but can an unlocked LG-G710TM work on Verizon? When I pop in my Verizon SIM (from S10), it registers on the voice network, but mobile data won't connect. The firmware (still v8.0.0) is all T-Mobile. Went to Verizon store, wait for the shock and horror, and they gave up after basic settings changes.
Just for kicks, if the 710TM can only work on T-Mobile, that makes unlocking this model somewhat pointless, no?
Thanks for any quick hits.

Back up your phone and flash with G710VM firmware which should allow it to work on Verizon. See link below with instructions.

Starting at post #55 in that thread, it says cross flashing the 710TM will brick it. Gotta ask the dumb question: did you point me there knowing that cross flashing the T-Mobile to Verizon will work or just knowing that there was a cross flashing thread that works for most G7s?
I"m appreciative for the help either way.

I don't have TM version so I was unaware of such restriction. My apologies the method will not work on your device.
If entering the Verizon APN info in (which I'm assuming the employees at VZW tried) still failed to produce results, then yes, you may be out of luck (however you could make use of a prepaid network that uses the T-Mobile bands such as Mint Mobile or sell it as a white-listed phone). This is why there are many of us with LG phones that wish they'd just release one model per device, as the Qualcomm chip used supports a wide range of bands used by various providers.
I picked up and unlocked an SM-N976U on AT&T and dropped in my Verizon SIM. All is well, expect for a few things. I was wondering about flashing the device with a "standard" firmware to remove the AT&T garbage but I cannot seem to find the details on how to do this. Any guidance? Thanks!

Hey the way to get unbranded is go to dialer and type *#272*IMEI NUMBER#
You'll get a screen that let's you choose the csc code. XAA is the generic unbranded. But from what I understand once you do it, it's hard to go back.
Try at your own risk. I think a guy said it messed up his bands or something like that.
@tyrone1... your instruction worked like a charm for me... I had SM-976U AT&T unlocked... I wrote down my IMEI and used *#272*My IMEI# and got a screen where I can make
Sales code and Network Change or Only Network Change.. I chose Sales code & Network Change and next screen I choose TMB.. after that I popped my TMB sim and it restarted my phone.
The phone booted with Tmobile splash.. and just verified that the Video call works (yaay)!!!
Thank you !!!!!!!
