times in a row, the phone will lock the
SIM card and prompt you to enter a PUK

same procedure as for the PIN code.
PUK Codes
A PUK code is the unlock code for the SIM
card. When the SIM card is locked, you have
to enter the correct PUK code and then enter
the new PIN code. The SIM card can then be
used normally.
• A PUK code may be supplied with a new
card. Contact your service provider for
more information.
• A PUK code can only be entered 10 times
in a row. If you enter the wrong PUK code
more than 10 times, the SIM card will be
locked indefinitely.
Note: If a PUK code is supplied with the
new card, please store it safely.
