Most iPhones purchased from AT&T are limited to the AT&T network. When a phone is unlocked, it implies that it is no longer limited to one network and can be used with any operator. To do this, AT&T must unlock the phone for you. In rare cases, phones can be "unlocked at the factory," which means that they were originally manufactured without any restriction, but these phones usually cost much more. So, if you want to visit another country (i.e., China, UK, France), you would not be able to use your iPhone there since it's locked on AT&T. In other words, if you want to use another carrier (i.e., Verizon), you must unlock AT&T iPhone.

Note: Unlocking your phone does not mean that passwords or data from your phone are erased.

Part 1. How to Unlock AT&T iPhone

Unlocking a phone at AT&T is a bit more complicated than at Verizon - although you have to take more steps, it was not difficult to finish it.

These are the requirements for unlocking your AT&T device:

  • You must be a former or current AT&T subscriber.
  • The device in question must come from AT&T.
  • If you are a current customer, your current contract or plan must be fully reimbursed (including early cancellation fees).
  • It may not be reported as lost or stolen.
  • It must be linked to an account "in good reputation," is not associated with fraudulent activity.
  • It may not be active on another AT&T customer account.
  • It must have been active for at least 60 days without "outstanding or unpaid balance."
  • If you have made an early upgrade, you must wait for the 14-day "Buyer's Remorse" period (30 days for business customers) before unlocking your old phone.

In contrast to Verizon, AT & T offers an unlock request form that you can complete online. You can enter your AT&T mobile number - or, if you have already changed the number, the IMEI number of your AT&T device will also work correctly. After you submit this form, you have 24 hours to click on the link included in the confirmation e-mail that you have been sent. AT&T will then send you instructions within two working days of the request to unlock your device by e-mail. Also, AT&T no longer has a fixed release limit per year. So if you send one hundred release requests per month, you do not have to worry about being reported as a suspect.
