About this DA678 × Smart unlock
Smart locks devices to its network when sold on contract or financed. Unlocking your DA678 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 DA678'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 DA678 unlock works regardless of which country it was originally sold in.

FAQ — DA678 on Smart
- Can Smart block this unlock?
- No. Once your DA678's IMEI is whitelisted on the manufacturer's database, Smart cannot reverse it.
- Will my DA678 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 DA678 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.
