SIM Operation Application Scenarios
Solution
If PIN authentication has
been enabled, it cannot be
enabled again. Check
whether PIN authentication
has been enabled.
Enter the correct PIN. The
original PIN is provided by
the operator.
Incorrect PINs have been
entered three times and the
SIM card is blocked. Run
AT+CPIN="<PUK>","<pwd>
" to enter the PUK to unblock
the SIM card. The PUK is
provided by the operator and
cannot be changed by users.
If incorrect PUKs are entered
10 times, the SIM card will be
permanently blocked.
<oldpwd> must be the
current PIN. Like the PIN
authentication, if incorrect
PINs are entered three times,
the PUK will be required. If
incorrect PUKs are entered
10 times, the SIM card will be
permanently blocked.
