11.2 Modem compatibility commands
This sub-clause describes how existing AT commands, designed for use with a modem, may be used to control a VGCS
or VBS supporting MT. This is to provide backwards compatibility with existing communications software.

Description
This Dial command extension is a service request application according to 3GPP TS 22.030 [19]. No further commands
may follow on the AT command line.
Responses
When the call has terminated, either as a result of an orderly termination or an error, the MT shall return the NO
CARRIER final result code.
Possible error responses include +CME ERROR: <err> when error is related to MT functionality. The requested
service, GId and priority level are checked against the subscriptions of the user and the status of the GId stored on the
SIM. In case if no subscription is available for this service, GId or priority level or the GId is deactivated an ERROR or
+CMEE ERROR result code is returned. See +CMEE ERROR extensions for VGCS, VBS and eMLPP in subclause
9.2.
Detailed error report of an unsuccessful originated call can be obtained with command Extended Error Report +CEER
(if implemented).
NOTE. The dial string conforms to the syntax specified in 3GPP TS 22.030 [19].
