Note:
If you attempt to use SMS related AT commands before insert ing a SIM card or entering the SIM PIN,
the resulting errors will be delivered in the form of CME errors instea d of CMS errors.
This is a normal behaviour since the GSM 07.05 based CMS errors are mapped to GSM 0 7.07 based
CME errors if SIM PIN authentication has not been done.
Example 1
The application tries to send a short message though the SIM card is no t present:
AT+CMGF=1
OK
