contacting me by phone

As I travel so much I have bought a mobile broadband dongle for my laptop, which is faster than my home phone broadband, as my house is so far from the telephone exchange, and is connected by old copper wiring, apparently. My home phone (landline) will be disconnected from 18th September so I will be reachable on mobile only. Only a few folks ever used my home phone anyway, except lots of telesales muppets. I may end up getting an incoming calls only home line, but I am not sure. My phone number is on the main Great River website.
