About this M4 × Tigo unlock
Tigo locks devices to its network when sold on contract or financed. Unlocking your M4 is straightforward once your account meets Tigo'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 M4's IMEI directly, and once approved, the device is permanently whitelisted. The unlock survives factory resets, OS updates, and SIM swaps.
Tigo country coverage
Tigo operates in 12 countries. Your M4 unlock works regardless of which country it was originally sold in.

FAQ — M4 on Tigo
- Can Tigo block this unlock?
- No. Once your M4's IMEI is whitelisted on the manufacturer's database, Tigo cannot reverse it.
- Will my M4 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 Tigo account credentials?
- No. We unlock by IMEI alone. You don't need to provide your Tigo username, PIN, or account number.
- What if my M4 is still on a Tigo 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.
