Used to attach the MS to, or detach the MS from, the GPRS/packet domain
service. After the command has completed, the MS remains in V.250
command state. If the MS 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 (enabled by the +CMEE command) are listed under “+CME ERROR
(Mobile Equipment Error Code)”.
Any active PDP contexts will be automatically deactivated when the
attachment state changes to detached.
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.
