20 INTRODUCTION: VOCABULARY
PIN2 code
You need a PIN2 code for setting and reset-
ting certain SIM functions, e.g. charge
counters and limits.
The PIN2 code (4 to 8 digits) is supplied by
your network operator.
If you enter the wrong PIN2 code three
times in a row, the SIM card will be dis-
abled. You then must use your PUK2 code
to enable the PIN2 code and the SIM card.
PUK code
The PUK code is used to open the disabled
SIM card. The 8-digit PUK code is normally
supplied with the SIM card.
The SIM card will be permanently disabled
after entering wrong PUK code ten times.
After that only emergency calls can be
made. Contact your network operator for a
new SIM card.
PUK2 code
The PUK2 code is used to open the disabled
PIN2 code. The 8-digit PUK2 code is sup-
plied with the PIN2 code.
In case your PUK2 code gets lost, contact
your network operator.
IMEI code
An IMEI (International Mobile Equipment
Identity) code is used to identify the mobile
phone. You will find your 15-digit IMEI
code easily from the type label of the
phone.
It is also recommended that you write down
your IMEI code and store it in a safe place.
This will help prevent unauthorized use of
the phone if it gets lost or stolen.
