others. Note that, if the input PIN code wrong three times,
the phone card will automatically lock and unlock

of danger, so if unauthorized modification of the PIN code,
we must bear in mind.

the SIM card PUK code is never used when the user
comes with the card, while the other part of the network
operators will need to obtain the PIN code if you do not
know the PUK code locked, do not random input, then the
correct way is to call the SIM card hotline operators, after
a simple user data are verified, you can obtain the PUK
password to unlock the phone lock, the service is free of
charge.
