+CGCLASS, GPRS Mobile Station Class
This command is used to set the G24 to operate according to the specified GPRS mobile class. If
the requested class is not supported, an ERROR or +CME ERROR response is returned.
Extended error responses are enabled by the +CMEE command.
Note: Issuing GPRS actions over a poor-quality connection may cause protocol errors and harm
data validity. To prevent these problems, G24 is equipped with a protection mechanism
that confirms GPRS signal strength before issuing GPRS network-related commands.
The following table shows the +CGCLASS parameters.
Example
AT+CGCLASS=?
+CGCLASS: (B)
OK
Note: If a SIM card without GPRS allowance is used:
AT+CGCLASS=?
+CGCLASS: (CC) //Note that CC is a not supported value.
