About this Sonim × Smart unlock
Smart locks devices to its network when sold on contract or financed. Unlocking your Sonim is straightforward once your account meets Smart'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 Sonim's IMEI directly, and once approved, the device is permanently whitelisted. The unlock survives factory resets, OS updates, and SIM swaps.
Smart country coverage
Smart operates in 4 countries. Your Sonim unlock works regardless of which country it was originally sold in.

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