AT+CGACT Activates or Deactivates Specified PDP
The execution command is used to activate or deactivate the specified PDP context (s). After the command
has completed, the MT remains in V.250 command state. If any PDP context is already in the requested state,
the state for that context remains unchanged. If the requested state for any specified context cannot be
achieved, an ERROR or +CME ERROR response is returned. Extended error responses are enabled by the
+CMEE command. If the MT is not PS attached when the activation form of the command is executed, the MT
first performs a PS attach and them attempts to activate the specified contexts. If the attach fails then the MT
responds with ERROR or, if extended error responses are enabled, with the appropriate failure-to-attach error
message.
If no <cid>s are specified the activation form of the command activates all defined contexts.
If no <cid>s are specified the deactivation form of the command deactivates all active contexts.
The read command returns the current activation states for all the defined PDP contexts.
The test command is used for requesting information on the supported PDP context activation states.
NOTE. This command has the characteristics of both the V.250 action and parameter commands. Hence it
has the read form in addition to the execution/set and test forms.
