Does AT&T lock phones?

Some AT&T devices may be network locked until the current eligibility requirements are met.

Who is eligible for an unlock?

• The device must meet AT&T's current eligibility requirements.
• Any applicable installment balance must be resolved.
• The device must not be reported lost, stolen, or involved in fraud.

How to request or confirm an unlock

1. Open the official policy and confirm current eligibility.
2. Submit the IMEI only through the official carrier channel.
3. Follow the model-specific instructions after approval.

iPhone, Android and unlock codes

An iPhone commonly receives a carrier-side activation-policy update rather than a numerical code.

An Android phone may unlock remotely, through a setting or with a code only where the carrier instructs.

SIM and eSIM information

SIM and eSIM compatibility are separate from network-lock status.

If the unlock or SIM test fails

• Check payment and account status before retrying.
• Distinguish a network lock from activation, APN, coverage and compatibility errors.
