What is PIN1?
PIN stands for Personal Identification Number. It serves as a secret code
required to use your phone to make or answer calls or to retrieve your personal
information (such as Phone Book data). Unless this password is entered
correctly, your phone cannot retrieve information required to enter Standby mode.
The password is a 4- to 8-digit, user-definable numeric code. Also you can
disable PIN1 if you prefer. If you disable PIN 1, you can retrieve the information
required for your phone to receive incoming calls and to make calls without
entering the password. If you enter the PIN1 code incorrectly 3 times in
succession, your SIM card will become locked. The number of times you enter
the PIN1 code is retained on the SIM card even after the phone is switched off.
Entering the valid PIN1 code clears the invalid-code memory.
What is PUK1?
When your SIM card becomes locked after you enter the PIN1 code incorrectly 3
times in succession, you can unlock your SIM card by entering the PUK1 code
(PIN Unblock Key 1). PUK is an 8-digit numeric code that cannot be changed by
the user. If you enter the PUK1 code incorrectly 10 times in succession, your SIM
card will become locked. The number of times you enter the PUK1 code
incorrectly is retained on the SIM card even after the phone is switched off. Once
the SIM card is locked through invalid PUK1 entry, there is no way for the user to
unlock the SIM card.
If your SIM card is PUK1-locked, contact your service provider to unlock it.
What is PIN2?
PIN2 is the secret password required to write/change/delete Fixed Dial phone
numbers, set/reset the call limit, or clear the cumulative call charge. This
password must be entered immediately before you can access PIN2-protected
data. Once you have entered your PIN2 code, it remains stored on the SIM card
until the phone is switched off but it must be entered whenever you attempt to
perform an operation involving PIN2-protected data. The password is a 4- to 8-
digit, user-definable numeric code. Unlike PIN1, you cannot disable PIN2 input.
If you enter the PIN2 code incorrectly 3 times in succession, your SIM card will
become locked. The number of times you enter the PIN2 code incorrectly is
retained on the SIM card even after the phone is switched off. Entering the valid
PIN2 code clears the invalid-code memory. To enter the PIN2 code, use the
same procedure as for the PIN1 code. (See page 24.)
What is PUK2?
When you have entered the PIN2 code incorrectly 3 times in succession, you can
unlock your SIM card by entering the PUK2 code (PIN Unblock Key 2). To enter
the PUK2 code, use the same procedure as for the PUK1 code. (See page 24.)
PUK2 is an 8-digit numeric code that cannot be changed by the user. If you enter
the PUK2 code incorrectly 10 times in succession, your SIM card will become
locked. The number of times you enter the PUK2 code incorrectly is retained on
the SIM card even after the phone is switched off. Once the SIM card is locked
through invalid PUK2 entry, there is no way for the user to unlock the SIM card. If
your SIM card is PUK2-locked, contact your service provider to unlock it.
