11.19 ATD*98# Request GPRS IP 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
layer 2 protocol.
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. If the context to be used
is already activated, it will be deactivated first. This ensures that the right context parameters will be used (e.g.
QoS changes since the last context activation).
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).
ATD*98# is blocked when the Fixed Dialing lock is enabled and the number "*98#" is not present in the "FD"
phonebook (see AT+CLCK SIM Fixed Dialing lock). In this case "+CME ERROR: call barred" is returned.
Syntax
Parameter Description

an internal context with default properties is used (see AT+CGDCONT, AT+CGQREQ and AT+CGQMIN).

Notes
• If BGS2T is in dedicated mode, command returns "+CME ERROR: phone busy".
• ATD is used as a standard V.250 AT command, too.
