with the use of a mobile phone.
SIM card
The SIM card supplied by your network op-
erator contains all subscriber-related infor-
mation, for example, your international
mobile subscriber identity (IMSI) number.
The SIM card memory can store phone
numbers and names.
If your SIM card gets lost or misplaced con-
tact your network operator immediately.
A phone without a SIM card can be used to
make only emergency calls.
PIN code
Your SIM card is protected by a PIN (Per-
sonal Identification Number) code of 4 to 8
digits. Using this code prevents unautho-
rized use of your phone and SIM card. Your
PIN code is normally supplied with the SIM
card.
Your phone prompts you to enter your PIN
code when you turn on the phone. You can
disable the PIN code request from the
menu, but it is recommended you keep the
request on. You can change the PIN code in
the menu.
If you enter the wrong PIN code three times
in a row, the SIM card will be disabled. You
then must use your PUK code to enable the
PIN code and the SIM card.
