I've just had a look at all of these. I don't really want to change my phone provider (tiscali) yet, as I get free calls to Australia and as my mother is 90 this year, want to be able to ring her as often and as cheaply (free!) as possible. I was tempted by BT , until realised how much the calls to Oz would be. Does anyone know if the other providers give cheap calls overseas please? I can't find it on Virgin or Fast (which seems a bit mor expensive per month than the others). Janet
