FAQ — CASA SYSTEMS on Cellcom

Can Cellcom block this unlock?
No. Once your CASA SYSTEMS's IMEI is whitelisted on the manufacturer's database, Cellcom cannot reverse it.
Will my CASA SYSTEMS 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 CASA SYSTEMS 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.
