modem router will show the default Dial Number and APN of that ISP.
¾ Always on: Connect automatically after the modem router is disconnected. This option is
enabled by default.

Idle) for a pre-specified period of time (Max Idle Time), the connection will tear down

If you want your Internet connection to remain active at all times, enter 0 in the Max Idle Time

Sometimes the connection cannot be disconnected although you specify a time to Max Idle
Time because some applications visit the Internet continually in the background.
