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