Protecting your SIM card with a PIN

Add another layer of security for your phone by assigning a PIN (personal identification number).

Make sure you have the default SIM PIN provided by your mobile operator before continuing.

1.On the Start screen, tap the Phone tile.

2.Tap ... , and then tap call settings.

3.Tap the SIM security On/Off switch.

4.Enter the default SIM card PIN, and then tap enter.

5.To change the SIM card PIN, tap Change SIM PIN.

Emergency calls can be placed at any time without requiring a PIN. See “Making an emergency call” in the Phone calls chapter for more details.

Restoring a SIM card that has been locked out

If you enter the wrong PIN more times than the maximum number of attempts allowed, your SIM card will become “PUK-locked.” You need a PUK code to restore access to the phone. This code may have been provided by your mobile operator when you received your SIM card.

1.On the Phone dialer screen, enter the PUK code, and then tap enter.

2.Enter the new PIN you want to use, and then tap enter.

3.Enter the new PIN again, and then tap enter.
