Question SIM Unlock AT&T Prepaid A12 - Samsung Galaxy A12

Does anyone know how to unlock the AT&T prepaid version (SM-A125U) of this phone? I don't know how long it was in service.
Looks like they're using an unlock app like T-Mobile is using.
I tried the AT&T website it told me to insert a different sim and it'll automatically ask you to unlock it.
I did that and it says "This device cannot be unlocked" see the support section for more info.

You can ask them if they can do it for you, you will need to provide them with the IMEI and serial code and they might ask for more.

It is always best to buy carier unlocked.

[Q] [q] d2g + us att sim?

So I've done a large amount of searching, not only on XDA but elsewhere to find a real 'answer' to my question, but I haven't found anything concrete, hence this thread.
I have aquired a Droid 2 Global from VZW for free, and I want to use it with my US ATT SIM, on the US ATT GSM Network.
Things i have done:
- Flashed the phone to the stock OS in order to....
- Flash the radio so it accepts ATT GSM signal
- Aquired the sim unlock code from ATT for my current phone/sim (I'm unclear on exactly what this whole sim unlock process is about, perhaps why I'm asking)
The phone boots, but when I have my SIM inserted, it asks for the unlock code.... What exactly IS it asking for?
The SIM unlock that I recieved from ATT doesn't work.. (I assume this is the unlock for my sim, in my current phone?)
What is the next step, if this is possible? I've looked at getting the phone unlock code via ebay, or one of the piggyback devices like TurboSIM, but I'm unsure what will work, if anything will work?
Help??
Thanks in advance for any info provided
It asks for the unlock code you can get from VZW's Global Support if you are a VZW customer.

Well, since I'm at ATT customer, how would I go about getting this code? I do have a friend that works for VZW, which is how i got the phone, and he is willing to assist me. Can he provide it?
The phone must be on an active line of service, and the billing history must be clean for the past 6 months.
If your friend works for Global Support, then maybe. If not, I doubt it.
Hmph..
I guess I overestimated the difficulty of getting this to work. It was just another case of having to get the unlock code from the phone itself via IMEI number,and yahtzee, working as I had hoped.
For some reason I had the notion that it was significantly more difficult after reading all of the posts about trying to get other SIMs to work.. but its actually very very straight forward and easy.. it just seemed that nobody had ever really made it clear that a US ATT sim could work on a VZW D2G handset with US ATT service.
Thanks for your input!

[Q] Need a quick answer please regarding T-Mob service.

Can someone please tell me if it is possible to use a prepaid Sim with a TMob Edge? If so would it have to be a Tmob brand Sim card? If this is not possible stock would it be possible through root access and possibly a rom change? I'd ultimately like to be able to use an AT&T prepaid sim. Thank you in advance for any info. I'm in a time crunch for this info so i really appreciate it.
P.S.- is this phone carrier unlocked out of the box?

The phone is not carrier unlocked out of the box. You will have to sim unlock through T-Mobile or another source if T-Mobile will not unlock it for you. It should work with an AT&T prepaid sim after you sim unlock.

Tmo will unlock it only if there is no balance on your phone. They will ask you why you want to unlock then give you the pin to unlock.

I just received my unlock code for my Note 4. They will actually send you the unlock code after 40 days of purchase. I am on jump and still paying for my device and now it's unlocked.!! Just call t-mobile after you have had your device for 40 days and request the code.

Do i need t mobile to unlock it even if it is rooted, what If i were to just flash say a stock at&t rom to the phone, could i then use am att prepay sim?
Thanks for the answrs!
Yes you need T-Mobile to unlock it. If not it doesnt matter if you have it rooted or not. You wont be able to use other sim cards or carrier's if you dont have it unlocked by T-Mobile.

So i just called and requested an international and carrier unlock. I was told that there was two ways to unlock it, first way being just a carrier unlock and second way being both international and carrier unlock which is what i requested. Then they asked for my imei and my email address and said that i would recieve the code and instructions via email within 24 hours. Is this the same process that you went through bryanthomas007? After completing this process is it possible to use a prepaid service?

SIM Unlock T-Mobile LG G5

Hello All,
Any recommendations to a website that will Sim Unlock my T-Mobile device to use it on international GSM?
Thanks
Are you currently a T-Mobile customer or no? If so you should be able to get them to unlock it for you. If not I don't know the answer.
Ebay and other unlocking sites offer the T-Mobile app unlock up for sale, anywhere between 25-50 bucks or so.
There is an app on there to check if you are eligible for unlock.
Traditionally, you could call T-Mo's Customer Care and request an unlock. They have been generally pretty lenient on letting people unlock (especially for long time customers).
However, seeing as there is this unlock app built in to the phone that has a temporary unlock option, you may only get authorized to use that until your phone is paid off or something to that extent.
It is definitely worth a call.

I purchased the phone from ebay USA, and i live abroad already. Then found out when i got the phone and tried using my local SIM that it were locked
But now i got it unlocked, for anybody else seeking unlock service PM me.
I'd remove the link if I were you....
Bought my wife's G5 from T-Mobile Online. Called to request to have it unlocked and they told me they have a 40 day waiting period then I can have it unlocked. They waived it immediately once I told them I was in the military and currently stationed overseas. Took about 6hrs to receive the unlock information.

Congrats. You saved the 40 days waiting. My case was different, after i purchased mine on ebay, i found out that the IMEI is blacklisted (outstanding balance), so i had to go to third party services.

Well, that sucks. I'll always buy from Swappa since I bought my LG v10 from there. Also remember, if you're buying a phone from someone, to ask for the IMEI to verify with the carrier that it isn't blacklisted. You probably actually paid the person enough so they can fix themselves.

Well, the issue was solved with 45$ I was in a hurry to buy it because the price was attractive and swappa had much higher prices. Well next time, for sure more investigation must be done before buying.
I dont mean to hijack this thread but it's exactly my problem. I have at&t in Iowa (pretty much no tmobile presence here) bought a brand new g5 off ebay wasnt paying attention to the fact that it was locked to tmobile. I did try a site that charges 30 something bucks to get it unlocked and they emailed be back the next day saying they couldnt do it. I checked the eimi or whatever on swappa, says its clean. I saw somewhere that the best way to get the unlock code is to order a prepaid sim and load some money on it and wait 2 weeks and then request the unlock code? I went to tmobile's website and got halfway through the prepaid sim screens but when i put the eimi number in it comes back with nothing, i am assuming thats because the phone has never been activated anywhere before? Appreciate the help, I dont want to pile more dumb on top of dumb...
I need help unlocking my LG g5. I bought it online through eBay from someone that works at LG.
The phone came sealed, I ordered a unlock code, but I discovered as soon as I turned it on that now I need to unlock through t-mobile device unlock app.
The site I ordered my code said they would change my status on the t-mobile database so I can unlock the device through the app.
I Googled around and that should have worked. But apparently my IMEI is not registered t-mobile.
I bought a prepaid Sim and put it on the phone. It's working at t-mobile but its still not at their database (the IMEI).
What should I do?
Is there any way to force the IMEI to t-mobile database so it can be unlocked through the third party?
Or is there any other way to unlock it.
Please help...

Did you try the permanent lock option on the t-mobile unlock app? What message did you get then?
So far I tried 2 different services and requested unlock code but none of them worked, they simply didn't get back to me with any results.
Can someone suggest one that actually worked for them please and PM me?
Thanks guys.

It says:
Unlock Failed: This mobile device is eligible for unlock. For device unlock eligibility details, please go online or contact Customer Support.
And even if I go online, to T-Mobile IMEI check website, it says my IMEI is not recognized at T-Mobile.
Thats the problem.
Although I'm using it at T-Mobile, and it is a T-Mobile branded phone.
And because it's not at the database, I can't do ANYTHING to try to unlock it through third parties.

Maybe it has been bought on contract and must have been activated first so that IMEI would be registered at T-Mobile.
Mine was blacklisted and i unlocked it. It shouldn't be a big deal for yours.
I would suggest drop T_mobile a visit or call, and check with them what is wrong.
Logically, if the IMEI is not on their database then it shouldn't be carrier locked.
I will drop you a PM for a contact that might help you in this issue.

Wrong my friend. If the phone is on TMO but IMEI is not in theit database that means phone wasn't activated on TMO network, which means you're not gonna be able to unlock it through official unlock app.
I wonder if this phone unlockeble at all without using that unlock app.

T-Mobile Samsung Note 20 is temporarily unlocked for 30 days, how do I prevent from it being locked again?

Long story short I bought a Note 20 Ultra from the U.S. which the seller advertised as unlocked, but it was locked to T-Mobile when I received it and I'm not able to return the phone. T-Mobile won't help cause the phone isn't paid off.
I tried to click "Permanent unlock" in the menu and it said not eligible, reason code 8. Then I tried temporary unlock and it unlocked the phone for a month.
My question is, is there a way to prevent my phone from being locked again?
If I flash the unlocked Samsung firmware on this, would that prevent it? If not, why? What exactly makes the phone locked again?
Any help would be appreciated. Thank you.

Flashing different firmware will have no effect on your SIM Locked status.
You're options are limited :
1) Pay the balance owed to T-Mobile.
2) Find a SIM Unlocking service that can SIM Unlock your phone. (If you go this route, be sure it's specific to the T-Mobile model).
3) Plead your case again to T-Mobile. They may allow for SIM Unlocking after a period of time, when they eventually write-off the debt owed on the phone.
Otherwise, you're stuck w/using it on T-Mobile or, the MVNOs that use their network.

Thanks. I've tried contacting T-Mobile and said I would pay any sort of fee to get it unlocked, and they keep telling me the original account holder has to call in and I can't do anything about it.
In terms of unlocking it with someone else, I talked to a few people yesterday and they all said the "server is offline".
I did talk to 1 person and they told me "one option by imei is 68 usd in 1-30 days"
I don't understand by imei means... I'm assuming he's saying to change the imei number?

No, that's probably not what the service you looked up meant.
There are some legit services out there that will SIM Unlock your phone, for a fee. They probably need the IMEI on your phone (use your phone's search function to find it) to permanently SIM Unlock your phone.
Changing the IMEI is illegal in a lot of countries & talk of it is expressly forbidden here on XDA.
Simply asking for services that change IMEI's here @ XDA will result in the thread being locked & possible banning of the OP on such threads if such actions do not immediately cease.
If you pursue IMEI changing here @ XDA, the mods will see it & PM you, if you're lucky, you'll get a warning before any bans are put in place.

Question App says unlocked, phone stays locked

Had a hell of a time speaking with T-Mobile representatives these last couple of days. Everyone has a different opinion on what I need to do to unlock my S22 Ultra. Just today a guy recommended I download the T-Mobile Device Unlock app off the Play store and it said the following:
"Your device is currently permantently unlocked and allowed to be used with any carrier. Restart your device to apply these changes if your device was previously locked." Yet I do that and it remains locked.
Anyone else had this experience? Not sure what I can do short of returning it.

If you're talking about OEM Unlocking, that is completely separate from carrier lock, and there's little the carrier can do about it.

No, I'm not. There was apparently someone before me. The phone is paid off and I do believe there isn't any custom firmware on it and I went through a series of updates since getting the phone.
If this indeed is a T-Mobile phone, you shouldn't need the T-Mobile unlock app. Just look around in Settings > Connections & look around for SIM unlock, network unlock or something along those lines (I'm running US unlocked firmware XAA, so, I don't have the unlock in my settings, otherwise, I'd be able to give you the exact terminology).
Anyway, once you've found it, you should be able to check for the SIM Unlock. If it says you're unlocked & you're still having issues, I'd call customer service.

I know that. I've been on the phone with them for over two hours already. I asked them to put in a request to unlock it given the previous owner's contract and filed a complaint with the FCC. The phone SHOULD be eligibile for unlocking but the carrier is just being stubborn.
