DeviceDecoded uses the manufacturer's official unlock channel. We submit your MASTONE's IMEI directly, and once approved, the device is permanently whitelisted. The unlock survives factory resets, OS updates, and SIM swaps.

FAQ — MASTONE on Three
- Can Three block this unlock?
- No. Once your MASTONE's IMEI is whitelisted on the manufacturer's database, Three cannot reverse it.
- Will my MASTONE 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 MASTONE 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.
