Parameter Storage: <class> is stored in EEPROM without using AT&W.
Examples:
This command is used to attach the modem to, or detach the modem from, the GPRS
service. After the command has completed, the modem remains in V.25ter command state.
If the modem is already in the requested state, the command is ignored and the OK
response is returned.
Any active PDP contexts will be automatically deactivated when the attachment state
changes to detached.
<state>
The set command is used to set the modem to operate according to the specified GPRS
mobile class.
