I just noticed your other message, if you are getting NO CARRIER then you might like to confirm that your service is enable for data calls, with some carriers this is an optional extra.

Question
what are the AT commands for SENDING phone number, username and Password in order to dial for accessing internet via GSM.
Hi All,
I have a LAPTOP with red hat LINUX installed, a GLOBETROTTER card to use as a MODEM for connecting internet via GSM connection and a SIM CARD from E-Plus.
may I know what are the AT commands for SENDING phone number, username and Password in order to dial for accessing internet.
I know that to dial using number the command is ATD++++++++++++; where + represents number. Please tell me whether I am right or wrong and If I am wrong please rectify me.
Please respond to this as early as possible.
Dinesh.

>I know that to dial using number the command is ATD++++++++++++;
ATD++++++++++++; will start a voice call, but ATD++++++++++++ will start a data call. If you dial ATD++++++++++++; to any kind of modem then you will get "No Carrier" as feedback.
More AT commands with explanation you will find on http://www.gsm-modem.de/gs

Hi drelectro and Meff,
Thanks for ur immediate response. Mr. drelectro the message which you sent that we can`t configure username and password using AT commands but are sent through ppp negotiation , it means we can dial an ISP using the command ATD in minicom and sending username and password by writing a scrip which uses PPP connection, you mean.
Please can u briefly exaplin me the procedure and how to send username and password via PPP.
thanks in advance.

For staright GSM circuit switched data this is no different to using any other modem.
The phone number is the phone number of your ISP and the command is ATD<number> as you suggest.
The username and password are not configured using AT commands but are sent during PPP negotiation.
The following document should help:
http://www.faqs.org/docs/L
IF you plan on using GPRS things are much the same except you dial *99# or *98# and you need to set the PDP context with the at+cgdcont= command (your carrier should have help document explaing how to set this for you network).
