Phone Lock

The phone lock protects your phone from unauthorized use. By
default, the phone lock is disabled. Once the phone lock is enabled,
you must enter the phone unlock code each time you power on the
phone. The preset phone unlock code is 1234. You can change this
code into any numeric string between four and eight digits.
If you forget the phone unlock code, contact your service provider.

unauthorized use. The PIN unblocking key (PUK) unlocks a blocked
PIN. Both the PIN and the PUK are provided with the SIM card. For
details, contact your service provider.
