Protecting your SIM card with a PIN
You can protect your SIM card from unauthorized use by assigning a PIN (personal
identification number).
The default SIM PIN is provided by your mobile operator.
1.
Press HOME > MENU, then tap Settings.
2.
Scroll down the screen, tap Security > Set up SIM card lock, and then select the Lock SIM
card check box.
3.
Enter the default SIM card PIN, and then tap OK. 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 Next.
2.
Enter the new PIN you want to use, and then tap Next.
3.
Enter the new PIN again, and then tap Next.
