Hello Sir,

it has been more than a weak I am stuck at this point, Please help.
AT+CGATT=1

AT+CGATT?
+CGATT: 1

AT+CGDCONT?
+CGDCONT: 1,"IP","rcomwap","0.0.0.0",0,0

OK

AT+CGDATA=1
ERROR
AT+CEER
+CEER: Regular deactivation

OK

In my provider doc i came across following, does this means my device will not allow GPRS connection using AT commands
GPRS mobile class descreption in document
“A” class A in 3G only mode
"B" class B
"CG" class C in GPRS only mode
"CC" class C in circuit switched only mod


I test following on my devise
AT+CGCLASS=?
+CGCLASS: ("A")
OK
AT+CGCLASS?
+CGCLASS: "A"

OK
AT+CGCLASS="CG"
ERROR

my device show class as "A" which is 3G only, i tried to change it to "CG" but it fails with an ERROR. does this means my device does not support GPRS mode, but explicity i can use internet on my mobile browser. i am bit confused on this. can you please cleary this.

Thank's in Advance
