Locking the SIM Card

Your PIN (Personal Identification Number) code protects 

the information stored on your SIM card. When the SIM 

card is locked, you must enter your PIN code to unlock the 

SIM card each time you turn on the phone or insert the 

SIM card in the phone.

Unblock the SIM Card PIN Code

If you enter an incorrect PIN code three times in a row, 

your SIM card is disabled and your phone displays SIM 

Blocked. You must enter a PIN unblocking key (PUK) code, 

which you can obtain from your service provider.

Caution: If the unblocking attempt is tried unsuccessfully 

10 times, the SIM card is permanently disabled and your 

phone displays SIM Disabled.
