Can I unlock a second-hand AT&T phone?

Can I unlock an AT&T phone purchased from Walmart, Best Buy or Amazon?
Yes. As long as the device is locked to AT&T, the original retailer does not affect the unlocking process.
Can I unlock an AT&T phone where a balance is owed?

The Unlock Process
How long does it take to unlock my AT&T phone?
The estimated turnaround time is 24-48 hours. Many AT&T unlocks are completed within the estimated timeframe, although some devices may take longer depending on the network and current processing times. We'll keep you updated by email throughout the process.
Do I need to send you my phone?
No. Everything is completed remotely using your device's IMEI number. Your phone stays safely in your possession throughout the entire unlocking process, and there is no need to post it to us.
Can I continue using my AT&T phone while it is being unlocked?
Yes. You can continue making calls, sending messages and using your phone as normal while your unlock request is being processed.
Will my unlock be permanent?
Yes. Our official IMEI unlocks are permanent. Once your phone has been unlocked, it will remain unlocked even after software updates or a factory reset.
Will unlocking my phone erase my photos, apps or contacts?
No. Unlocking only removes the network restriction from your phone. Your photos, contacts, apps, messages and other personal data remain completely untouched.
Do I need any technical knowledge to unlock my phone?
