About this Billion × Cellcom unlock

Cellcom locks devices to its network when sold on contract or financed. Unlocking your Billion is straightforward once your account meets Cellcom'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 Billion's IMEI directly, and once approved, the device is permanently whitelisted. The unlock survives factory resets, OS updates, and SIM swaps.

Cellcom country coverage

Cellcom operates in 2 countries. Your Billion unlock works regardless of which country it was originally sold in.

FAQ — Billion on Cellcom

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