About this Teesso × Three unlock
Three locks devices to its network when sold on contract or financed. Unlocking your Teesso is straightforward once your account meets Three'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 Teesso's IMEI directly, and once approved, the device is permanently whitelisted. The unlock survives factory resets, OS updates, and SIM swaps.

FAQ — Teesso on Three
- Can Three block this unlock?
- No. Once your Teesso's IMEI is whitelisted on the manufacturer's database, Three cannot reverse it.
- Will my Teesso 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 Three account credentials?
- No. We unlock by IMEI alone. You don't need to provide your Three username, PIN, or account number.
- What if my Teesso is still on a Three 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.
