APPENDIX D: SIM CARD DEFINITIONS
SIM CARD AND PIN CODE
PIN stands for Personal Identity Number. SIM stands for
Subscriber Identity Module. A PIN code is usually supplied
with a SIM card. The PIN code protects your phone against
unauthorized use; without a PIN code, the SIM card is unable
to access the network and therefore cannot be used. Your PIN
code enables your SIM card to access your provider’s
network. Each time your phone is switched ON, you will be
prompted to type your PIN code. If you type an incorrect PIN
code three times in succession, the SIM card will be blocked.
You will then be required to type in the PUK code in order to
unblock the SIM card. If no PIN code was supplied with your
SIM card, contact your service provider.
PUK CODE
PUK stands for Personal Unblocking Key. The PUK code is
required to unblock a SIM card that has been blocked. A PUK
code is usually supplied with a SIM card. If no PUK code was
supplied with your SIM card, contact your service provider.
