Issue Description
==================

Will need to define a config variable to enable/disable this functionality as well as one
to control whether Wifi is preferred (generally it will be, but nice to have the choice).

It'd be good to have support for establishing connection via a 3G dongle - perhaps if Wifi
connections fail? Would also mean a PAYG dongle could be attached, but only topped up if
the car goes missing - that way VehManPi could report its location even if there are no
Wifi points available.

Should be as simple as

After plugging the dongle in, dmesg shows the following

After configuration (wvdial.conf contents below), wvdial detects the GPRS stick but
consistently getting NO CARRIER. Have plugged my contract SIM into the stick, so it's
either that the stick genuinely can't get a connection or there's something wrong with the
config.

Created a Udev rule to ensure the modem always becomes /dev/GPRS

Bulk Close.

Realistically, project isn't going to see any further development so closing as Won't Fix
