14.5.6 Notes
Before the activation of the context, the MT has to attach itself to the GPRS network,
if necessary.
If a GPRS PPP session is already running, the setting of a CSD (GSM data call) is not
supported.
If the MT is not GPRS attached when the activation form of the command is
executed, the MT first performs a GPRS attach and then 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 the first
possible within the defined contexts. If no <cid>s are specified, the deactivation form
of the command deactivates all active contexts.
