About this Microsoft × ATT unlock
ATT locks devices to its network when sold on contract or financed. Unlocking your Microsoft is straightforward once your account meets ATT's eligibility criteria — typically the device must be paid off and not reported lost or stolen.
DeviceDecoded uses the manufacturer's official unlock channel. We submit your Microsoft's IMEI directly, and once approved, the device is permanently whitelisted. The unlock survives factory resets, OS updates, and SIM swaps.

FAQ — Microsoft on ATT
- Can ATT block this unlock?
- No. Once your Microsoft's IMEI is whitelisted on the manufacturer's database, ATT cannot reverse it.
- Will my Microsoft stay unlocked after a factory reset?
- Yes. The unlock is permanent at the factory level — it persists through factory resets, OS updates, and SIM changes.
- Do I need my ATT account credentials?
- No. We unlock by IMEI alone. You don't need to provide your ATT username, PIN, or account number.
- What if my Microsoft is still on a ATT payment plan?
- It depends on the device's status. Start with the eligibility check at our unlock checkout — that page explains how the two-stage payment works before you commit.
