Notes
• Caution: After entering a password with AT+CPIN all other
commands that need access to data on the SIM card may be blocked
for up to 20 seconds!
• Successful PIN authentication only confirms that the entered PIN
was recognized and correct. The output of the result code OK does
not necessarily imply that the mobile is registered to the desired
network. Typical example: PIN was entered and accepted with OK,
but the ME fails to register to the network. This may due to missing
network coverage, denied network access with currently used SIM
card, no valid roaming agreement between home network and
currently available operators etc.
ME offers various options to verify the present status of network
registration: For example, the AT+COPS command indicates the
currently used network. With AT+CREG you can also check the
current status and activate an unsolicited result code which appears
whenever the status of the network registration changes (e.g. when
the ME is powered up, or when the network cell changes).
• Wait 10 seconds after PIN input before using SMS related
commands.
- and can also be entered in quotation marks
(e.g. "1234").
- To check the number of remaining attempts to enter the
passwords use the AT^SPIC command.
- See AT+CPWD and AT^SPWD for information on passwords.
- See AT+CLCK and AT^SLCK for information on lock types.
4.1.1 What to do if PIN or password authentication fails?
PIN1/PUK1:
After three failures to enter PIN 1, the SIM card is blocked (except for
emergency calls). + CME ERROR: 12 will prompt the client to
unblock the SIM card by entering the associated PUK (= PIN
Unblocking Key/Personal Unblocking Key). After ten failed attempts
to enter the PUK, the SIM card will be invalidated and no longer
operable. In such a case, the card needs to be replaced. PIN1 consists
of 4 to 8 digits, PUK1 is an 8-digit code only. To unblock a disabled
PIN1 you have two options:
- You can enter AT+CPIN=PUK1 ,new PIN1.
- You can use the ATD command followed by the GSM code
**05*PUK*newPIN*newPIN#;.
