How to Unlock Your AT&T-Locked iPhone for Free by Contacting AT&T Support

It looks like AT&T have started unlocking iPhones (via Apple) over the weekend. Need to unlock yours too? Simply follow the steps below.

1. Firstly, find out if you’re eligible for this free unlocking service.
2.  Allocate 20-30 minutes of quiet time so that you can speak or chat properly with an AT&T’s customer support representative.
3. Once you’re ready, get your AT&T account number ready and have your iPhone in front of you.
4. Call this number 1-800-331-0500 or login to your AT&T online account to initiate a Live Chat session with an AT&T’s customer support representative.
5. They will ask a couple of questions but mainly will ask for your account information, email and your iPhone’s IMEI number. Go to Settings > General > About. Scroll down to get your iPhone’s IMEI number.
6. If there’s no issue with your account, they will issue the unlock and instructions within a few hours (some are given 24-48 hours). If this is not the case, they may have to do further checks. In this instance, they will give you a ticket number and inform you that somebody will be in touch with you within a week or by April 16th.

7. Once AT&T confirms your eligibility, they will send you the instructions as shown above. Do note that restoring your device with a stock firmware will wipe out your jailbreak.
Think of this as the officially IMEI unlocking which was offered by various vendors not too long ago. Apple is the one who does the unlocking, not AT&T.
