About this M3 MOBILE × Three unlock

FAQ — M3 MOBILE on Three

Can Three block this unlock?
No. Once your M3 MOBILE's IMEI is whitelisted on the manufacturer's database, Three cannot reverse it.
Will my M3 MOBILE 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 M3 MOBILE 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.
