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

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