IS THERE ANYONE WHO CAN HELP ME?

which interface should i use?

selint0 or selint2?

i sent all above at commands by selint2. so i tryed by selint0 also.

but at#sgact, at#scfg, at#sd commands only replied “operation not supported”… what should i do?

i read that selint0 is for gprs use.

do i have to postpaid sim? now i’m prepaid user.

and i think there isnt any userid or password at this operator.

and error for sd=1,0,80,“www.google.com” is cannot resolve DN

but at#sgact=1,1 works well and can get ip address for response.

ok i got the answer for my error. it was wrong APN. even though i can gets the IP, that APN was for WAP connection.

now is the next round !! thanks
