Defined Values
<class>: a string parameter which indicates the GPRS mobile class (in descending order of functionality)
z A class A (highest)
z B class B
z CG class C in GPRS only mode
z 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 TF 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 attchment (see remark above) :
AT+CGCLASS?
+CGCLASS: “B”
OK
AT+CGATT?
+CGATT: 0
OK
AT+CGCLASS=”CG”
OK
AT+CGATT?
+CGATT: 0
OK
