Locking/unlocking the SIM card
You can create a PIN code to lock your MiFi SIM card on the Admin web UI (Settings > Advanced > SIM). When the SIM is locked, your MiFi will not have access to the internet. A display appears in the InfoPanel of the Home screen.
Tap the message to unlock the SIM card. Or you can tap Unlock SIM from the Help menu.
Enter the PIN and tap Enter.
CAUTION: If you run out of PIN attempts, your SIM is PUK (personal unblocking key) locked and you must contact your network operator for the PUK code. You must enter the PUK code in the Admin web UI. If you enter the wrong PUK code, your SIM card will be permanently locked.
