SIM Operations
The actions available depend on the current SIM status. If multiple operations are possible, a
"Desired action" select list is visible. Use this to choose the desired operation.
PIN Lock
: If the SIM is currently PIN locked, you are prompted to enter the PIN. Note that if an
incorrect PIN is entered too many times, the SIM becomes PUK locked. An on-page counter
indicates how many incorrect entries will cause PUK lock. Once PUK locked, the PUK must
then be obtained from your service provider.
PUK Lock
: If the SIM is currently PUK locked, the only operation possible is to enter the PUK.
Note that if an incorrect PUK is entered too many times, the SIM becomes permanently
unusable. An on-page counter indicates how many entry attempts remain.
Enable PIN Lock
: This sets the SIM so that entry of a PIN is required upon startup to connect
to the mobile network. To perform this operation, you must enter the current PIN.
Disable PIN Lock
: You can use this setting to disable a previously enabled PIN lock. It reverses
the PIN lock, so that entry of a PIN is no longer required to connect to the mobile network. To
perform this operation, you must enter the current PIN.
Change PIN
: To change the existing PIN, select this option and then enter the required data:
1. Current PIN
2. New PIN
3. Confirm new PIN
For most SIMs, the new PIN must consist of 4 digits.
The default value is often 0000 or 1111.
