PIN2 and PUK Codes

PIN2 codes are used for some settings. To change the PIN2 code, use the same procedure as outlined above for the PIN code.

A PUK code is the unlock code for the SIM card. This code can be used to unlock a SIM card when you have entered the wrong PIN code 10 times. When you enter the correct PUK code, you will be able to re-assign a new PIN code, after which the SIM card can be used normally. Contact your service provider for more information.

A PUK code can only be entered 10 times in a row. If you enter the wrong PUK code more than 10 times, the SIM card will be locked indefinitely.

Note: If a PUK code is supplied with your SIM card, store it securely.

Fixed Dialing

If you set Fixed Dialing Status to On, you can only dial numbers on the Fixed Dialing Numbers list. You will need to enter your PIN2 code to use this feature.

Master Clear/Reset
