10.7. AT+CGACT Activate or Deactivate PDP Context
The Write Command is used to activate or deactivate the specified PDP context(s). After the command
has been 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 MT is not PS attached when the
activation form of the command is executed, the MT first performs a PS attach and then attempts to
activate the specified contexts. If no <cid>s specify the activation/deactivation form of the command, it
will activate or deactivate all defined contexts.
