11.18 ATD*99# Request GPRS service
This command causes the MT to perform whatever actions are necessary to establish a communication between
the TE and the external PDN.
The V.250 'D' (Dial) command causes the MT to enter the V.250 online data state and, with the TE, to start the
specified layer 2 protocol. No further commands may follow on the AT command line. GPRS attachment and
PDP context activation procedures may take place prior to or during the PDP startup if they have not already
been performed using the
AT+CGATT
and
AT+CGACT
commands.
Examples on how to use this command are provided in "Section 11.22 , Using GPRS AT commands (Examples) ".
To confirm acceptance of the command before entering the V.250 online data state command will respond with
CONNECT.
When the layer 2 protocol has terminated, either as a result of an orderly shut down of the PDP or an error, the
MT enters V.250 command state and returns NO CARRIER (for details refer to Section 11.5.1 , Automatic deac-
tivation of PDP context during dial-up PPP ).
