SIM card
When you register as a subscriber with a network operator,
you get a SIM (Subscriber Identity Module) card. The SIM card
keeps track of your phone number, the services included in
your subscription, and your phonebook information, among
other things.
PIN (Personal Identification Number)
You may need a PIN (Personal Identification Number) from
your network operator to activate the services in your phone.
Each PIN digit appears as *, unless it starts with emergency
number digits, for example 112. This is so that you can
see and call an emergency number without entering a PIN
% 16 Emergency calls. Press to correct mistakes.
If you have been using a SIM card in another phone,
make sure that your information is saved to the SIM card
before you remove it from the other phone.
If you enter the wrong PIN three times in a row, the SIM
card is blocked and the message PIN blocked appears.
To unblock it, you need to enter your PUK (Personal
Unblocking Key) % 38 Locks.
