FAQ — Viettel 2G SUMO on Alltel

Can Alltel block this unlock?
No. Once your Viettel 2G SUMO's IMEI is whitelisted on the manufacturer's database, Alltel cannot reverse it.
Will my Viettel 2G SUMO 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 Alltel account credentials?
No. We unlock by IMEI alone. You don't need to provide your Alltel username, PIN, or account number.
What if my Viettel 2G SUMO is still on a Alltel 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.
