Well spotted!
The responses did refer mostly to the system used to identify local programming for terrestrial DVB broadcasts. FREESAT relies on a telephone link and/or personal registration details to identify suitable local programming for your location. Virtually all media providers require some form of registration for administrative purposes, although this is really used primarily to target you with directed advertising, junk mail, and spam emails. If no area can be identified for some reason, I believe the default setting is London.
