PIN OR PIN2
PINs or PIN2s have 4-8 digits.
These codes protect your SIM card against unauthorised use or are required to
access some features. You can set your phone to ask for the PIN when you switch it
on.
If you forget the codes or they aren't supplied with your card, contact your network
service provider.
If you enter the code incorrectly 3 times in a row, you'll need to unblock the code
with the PUK or PUK2 code.
PUK OR PUK2 CODES
PUK or PUK2 codes are required to unblock a PIN or PIN2.
If the codes are not supplied with your SIM card, contact your network service
provider.
LOCK CODE
Also known as a security code or password.
The lock code helps you protect your phone against unauthorised use. You can set
your phone to ask for the lock code that you define. Keep the code secret and in a
safe place, separate from your phone.
If you forget the code and your phone is locked, your phone will require service.
Additional charges may apply and all the personal data on your phone may be
deleted.
For more information, contact the nearest care point for your phone or your phone
dealer.
