ATT Device Unlock

If you have an AT&T phone or tablet purchased from AT&T and are looking to take it to another carrier such as T-Mobile or a T-Mobile MVNO you may need to have the phone unlocked before you can take it elsewhere.  The following is a guide to show you how you can unlock your AT&T device.  Note, unlocking your device is free of charge through AT&T.  You should not be or have to pay a third party to unlock your device provided that it meets the conditions for unlocking.

Conditions for Unlocking

  1. The device must not have been previously reported lost, stolen or associated with fraudulent activity. 
  2. If you purchased your phone or tablet on contract or on an installment plan it must be fully paid off before it can be unlocked.  If your device was activated with the service commitment or installment plan your account must be active for at least 60 days with no past due/unpaid balances.
  3. The device must not be active on a different customers AT&T account.
  4. AT&T will unlock phones for persons who have never had an AT&T wireless account.

 

GoPhones

Officially, AT&T states that GoPhones can be unlocked but generally they must be active for at least 6 months of paid service as a GoPhone customer.  However, it has been reported that AT&T is willing to unlock brand new GoPhones as long as they have NOT been activated.  It is advised that when you request the device to be unlocked that you select Non-AT&T Mobility customer as the customer type even though there will be an option to select prepaid/GoPhone customer. (Updated: 12/14/2015.  This method worked for me.  I was able to unlock two Microsoft Lumia 640 GoPhone's that were brand new and unused.  AT&T sent me the unlock code 24h after requesting it).

 

Deployed Military Personnel

AT&T will unlock devices for active and deployed military personnel provided that they verify their deployment information.  Military personnel can get their devices unlocked even if they have an installment plan or other service commitment, however, AT&T reserves the right to limit the number of devices military personnel can unlock.

 

Early Upgrades

If you upgraded to a new phone under an AT&T early upgrade policy such as AT&T Next, you must complete 14 days of use on the network with the new device before requesting the old one to be unlocked.

How to Unlock

Once you have determined that your AT&T device is eligible for unlocking you can head over to https://www.att.com/deviceunlock/ and scroll down the page to where it says "I have read and agree to the eligibility requirements to unlock my device," tick the box and click continue.  Fill out the form that you are presented with and AT&T will email you unlock instructions with your unlock code after 2-5 business days, free of charge.  Please note, that to unlock your device you will need to have a non AT&T SIM card on hand.  AT&T will mention this in the email they send you if your device meets the qualifications to get unlocked.  Specifically you will need to have a T-Mobile or T-Mobile MVNO SIM card or other SIM card on hand to unlock your device.  AT&T MVNO SIMS will not work, as the they still use AT&T's network and your device generally does not need to be unlocked to use them.

If after following all the steps outlined here, and you find out that AT&T won't unlock your phone, you may want to give our partners from Mobile Unlocked a try to see if they can help.

How can your partners from Mobileunlocked unlock a prepaid phone? I tried several services incl. attunlocker.us and none of them can unlock it until you have 6 months of service on At&t network fulfiled.

I have an ATT bought galaxy7, I did get the unlock code from ATT, I inserted a SIM from wal-mart family mobile , only to find the att unlock code does not work. ATT will not discuss it with me because the idiot CS person says he has to have the secret pin for the orginal owners account. The original owner is dead.. I cannot ask her for her pin. Anyone have any advice for an ” incorrect unlock code” ? I have entered it 3 times,I do NOT want to do it 5 times and have the damn thing… Read more »

So it seems that atthas changed their policy of unlocking GoPhones as I purchased a Alcatel Allura last week at Walmart for my 12 year old son at my local Walmart store on clearance for $30, I intended to use it for T-MOBILE but att denied by unlock request saying that you now need 6 months of active paid service to unlock. Hopefully someone on eBay can get me a u lock code for about $15-16. Just wanted to give this FYI update. ????

I just purchased an LG B470 flip phone (ATT GO Phone) from best buy. I put my MVNO sim card in, turn it on and it worked. No unlocking required. I was shocked.

hi, when i introduce the IMEI the page says:
The IMEI you entered does not appear to be an AT&T wireless phone or tablet. Please re-enter the correct 15-digit IMEI number for your AT&T wireless phone or tablet. You can obtain the IMEI number from the wireless phone by dialing *#06#.

I will never, ever give another scrap of my money to AT&T. My husband bought an unlocked, full price iPhone SE. We then decided to get a “pay as you go” GoPhone deal. I specifically told the woman at the AT&T shop that we are only in the US for the summer, and that we only wanted 5-7 weeks of phone use before we removed the SIM and went back to work in Indonesia. Well, guess what? They have effectively locked my husband’s phone for 6 months. So much for explaining our needs. At any moment, this sales woman could… Read more »

Have you asked for them to unlock it? Did they give you a reason for locking it?

Hi Best
We spent a long time on the phone and the guy we spoke to was very sympathetic. He said they would send on an unlocking code from his supervisor, but all we ended up with was a “standard” email which basically said “sod off and pay us for 6 months.” _SIGH_

The way to unlock has changed, now there are 2 option to choose from;
AT&T wireless customer: YES or NO
If your are a customer your request number gonna be: CULxxxxxxxxxxx
Non customer is: NULxxxxxxxxxxxx

After 6 months waiting, now ATT has my IMEIs in their database. Now I can request the unlock code.

Hope this info can be helpful.

How do you got unlocking your Microsoft Lumia 640 GoPhone through “Non-AT&T Mobility customer”? Do you wrote the IMEI number from the box without turning on the cellphone or is mandatory (turn on) to insert a non AT&T simcard (so ATT identify the cellphone IMEI on their system, so you can request unlock code)? I tried to request an unlock code using a brand new (sealed) GoPhone (from Walmart) with the IMEI number from the box, am got this: “Error: We found no record of the IMEI Number you entered. Check your device’s 15-digit IMEI Number by dialing *#06# (errorCode.ULP2003)”… Read more »

Yes, I used non att mobility customer. I’ve actually unlocked two of them now, one purchased from Target and the other from the Microsoft Store. Surprisingly they both had different packaging, but unlocking worked the same way none the less. I did not turn either phone on ever, until I got an unlock code from AT&T. I just used the number that was on the box the phone came in. I don’t have the packages on me right now, to give any more information about the number. Does your phone look like it’s been opened before? I actually returned one… Read more »

Thanks for your reply: Not opened, completely sealed from Walmart, I bought 3 Kyocera Hydro Air (GoPhone) on Black Friday Sale, all have the IMEI number on the bottom of the plastic package. Tried to unlock request 2 of them and got the same error code, called AT&T customer service (the guy was a little rough to me) he said: use the IMEI info to request the unlock code on their website, but he was not clear to if the device need to be turn on without the sim, I explained that using the online request form doesn’t work and… Read more »

I’ll take a look at the box for the 640 later and let you know if I have any suggestions.

Understand that…

and thanks again,
I don’t have any idea if really need to turn on the device (the ones that sell Walmart) to get the unlock code.

For now, don’t turn them on. I’m not completely sure they can be unlocked if you do, but if you must turn one on, pull out the sim card before you do. That should help mitigate risk.

I can tell from the packaging, it is the same packaging as Targets. Can you return open package to Walmart? I did to Target.

Perhaps you can open one package and pull a battery to see if the information contained there is different from the box?

I can try on my end even if you send picture.

Its possible to return a open or any item to Walmart. But I’m gonna try turn on without the sim. Let you know my experience.

Ok, I opened the package, pulled out the SIM, I turned on the device check the IMEI using *#06# and the back of the phone. it’s the same IMEI as the retail package, after a couple of minutes I decided to request the unlock code. I got the confirmation email, BUT 5 minutes later I received a second email that said: “Unfortunately, your unlock request was denied because:

The IMEI number 014400001623244 you entered does not match a device compatible with the AT&T network.”

Come on what the…! Seriously!
