How to Unlock an Android Phone That Is Locked to AT&T
If an Android smartphone is locked to the AT&T network and won't accept a SIM card from another carrier, you may be able to unlock it through AT&T. The unlock process is free when the device meets AT&T's eligibility requirements.
1. Find the Phone's IMEI Number
First, find the phone's IMEI number. On most Android smartphones, go to:
Settings → About phone → Status or IMEI information
You can also try dialing:
*#06#
Write down the IMEI number because it will be needed for the AT&T unlock request.
2. Go to AT&T's Official Unlock Website
Visit the official AT&T Device Unlock Request page:
AT&T Device Unlock Request
Choose the option indicating that you don't have an AT&T mobile number if the phone isn't currently associated with your AT&T service.
Enter the requested information, including the phone's IMEI number.
3. Confirm the Unlock Request by Email
After submitting the request, AT&T may send a confirmation email.
Open the email and follow the instructions to confirm the request. Be sure to complete this step within the time period specified in the email, or the request may be canceled.
4. Wait for AT&T to Process the Request
AT&T will check the phone's eligibility.
Generally, the device must meet AT&T's requirements, which can include being paid off, not being reported lost or stolen, not being associated with fraud, and not currently being active on another AT&T account.
If the phone qualifies, AT&T will provide instructions for completing the unlock.
5. Complete the Unlock
The exact procedure can vary depending on the Android phone.
Some phones unlock automatically after AT&T approves the request. Other Android phones may require you to restart the device, insert a SIM card from another carrier, or follow additional on-screen instructions.
After the unlock is completed, insert the SIM card from the new carrier and restart the phone.
What If AT&T Says the Phone Is Active on Another Account?
One of the most important errors you may encounter is:
"The device you want to unlock is active on another AT&T account. The account owner needs to remove the device from their account."
If you receive this message, the phone cannot normally be unlocked through the standard unlock request until the device is removed from the previous AT&T account.
If the phone was purchased used or refurbished, contact the seller and explain that AT&T's unlock system shows the device is still active on another AT&T account. The seller may need to have the previous account association resolved or provide a replacement/refund.
Important: Don't Pay for Random Unlock Services
Be careful with websites that claim they can instantly unlock an AT&T phone for a fee. If AT&T is refusing the unlock because of an account, lost/stolen status, payment issue, or another eligibility problem, a legitimate third-party service generally cannot simply override AT&T's records.
The safest approach is to use AT&T's official unlock process and resolve any eligibility problem with AT&T or the phone's seller.
Final Tip
Before buying a used or refurbished AT&T Android phone, check whether it is already unlocked. A phone can look completely normal and still be network locked to AT&T. If the phone is intended to be used with T-Mobile, Verizon, or another carrier, verify its unlock status before completing the purchase. #unlockphone
