12.2.5 +CGATT, GPRS Attach or Detach

This command attaches/detaches the ME to/from the GPRS service. When the command has completed,
the ME remains in V.25ter command state. If the ME is already in the requested state, the command is
ignored and the OK response is returned. If the requested state cannot be achieved, an ERROR or +CME
ERROR response is returned. Extended error responses are enabled by the +CMEE command. Any
active PDP contexts will be automatically deactivated when the attachment state changes to detached.
