Moxa Technologies G2150I manual Select Service for MO SMS Messages +CGSMS, 10-10

OnCell G2150I AT Command Set		GPRS Commands
	AT+CGCLASS=?	+CGCLASS: (“CG”,”CC”)
		OK
	AT+CGCLASS?	+CGCLASS: “CC”
		OK

Defined values:

<class>: a string parameter that indicates the GPRS mobile class (in descending order of functionality)

‧A class A (highest)

‧B class B

‧ CG class C in GPRS only mode

‧CC class C in circuit switched only mode (lowest)

Other values are reserved and will result in an ERROR response to the set command. If the MT is GPRS attached when the set command is issued with a <class> = CC specified, a GPRS detach request is sent to the network. If the MT is GSM attached when the set command is issued with a <class> = CG specified, a GSM detach request is sent to the network.

Class A is not supported by G2150I GPRS software.

Remark: During switch-On in CG class, the MS always performs an automatic GPRS attach (the ATTACH-STATUS parameter of +WGPRS is ignored). But, if the MS is not already GPRS attached when switching from B/CC class to CG class then no automatic GPRS attach is performed.

Example about automatic attachment (see remark above):

AT+CGCLASS? +CGCLASS: “B” OK AT+CGATT? +CGATT: 0

OK AT+CGCLASS=“CG” OK AT+CGATT?

+CGATT: 0

OK AT+CGATT=1

OK AT+CPOF OK AT+CFUN=1

OK AT+CGCLASS? +CGCLASS: “CG” OK AT+CGATT? +CGATT: 1

OK
