+CFUN - Set Phone Functionality
enabled the DTR line and wait for the CTS (RS232) line to go in ON status.
while the DTR line is ON, the module will not return back in the power saving condition.
Note: The power saving function does not affect the network behavior of the module.
Even during the power save condition, the module remains registered on the network and
reachable for incoming calls or SMS. If a call incomes during the power save, then the
module will wake up and proceed normally with the unsolicited incoming call code

Enter PIN - +CPIN
+CPIN - Enter PIN
AT+CPIN=
<pin>
[,<newpin>]
Set command sends the device a necessary password before it can be operated (SIM
PIN, SIM PUK, PH-SIM PIN, etc.).
If the PIN required is SIM PUK or SIM PUK2, the <newpin> is required. This second
pin, <newpin> will replace the old pin in the SIM.
The command may be used to change the SIM PIN by sending it with both parameters
<pin> and <newpin> when PIN request is pending; if no PIN request is pending the
command will return an error code and to change the PIN the command +CPWD must
be used instead.
Parameters:
<pin> - string type value
<newpin> - string type value.
To check the status of the PIN request use the command AT+CPIN?
Note: If all parameters omitted then the behaviour of Set command is the same as Read
command.
AT+CPIN? Read command reports the PIN/PUK/PUK2 request status of the device in the form:
+CPIN: <code>
where:
<code> - PIN/PUK/PUK2 request status code
READY - ME is not pending for any password
SIM PIN - ME is waiting SIM PIN to be given
SIM PUK - ME is waiting SIM PUK to be given
PH-SIM PIN - ME is waiting phone-to-SIM card password to be given PH-FSIM PIN
- ME is waiting phone-to-very first SIM card password to be given PH-FSIM PUK -
ME is waiting phone-to-very first SIM card unblocking password to be given SIM
PIN2 - ME is waiting SIM PIN2 to be given; this <code> is returned only when the
last executed command resulted in PIN2 authentication failure (i.e. +CME
ERROR: 17)
SIM PUK2 - ME is waiting SIM PUK2 to be intered. this
