About this S SMOOTH × Three unlock

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

  • 🇦🇺 Australia
  • 🇦🇹 Austria
  • 🇮🇪 Ireland

FAQ — S SMOOTH on Three

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