6.1.4 AT+CGDCONT Define PDP Context
Test command
AT+CGDCONT=?
The test command returns values supported as a compound value. If the
MT supports several PDP types, the parameter value ranges for each
<PDP_type> are returned on a separate line.

This command specifies PDP context parameter values for a PDP context
identified by the (local) context identification parameter, <cid>. A special
form of the set command, +CGDCONT= <cid> causes the values for con-
text number <cid> to become undefined. AT&F and ATZ will undefine
every context which is not active or not online.

Parameter
<cid>
This PDP Context Identifier is a numeric parameter
which specifies a particular PDP context definition.
The parameter is local to the TE-MT interface and is
also used in other PDP context-related commands. If
no cid is given, nothing will be changed (neither con-
text definition nor undefinition).
