Ugh... good point...
That site shows several UMTS (3G?) sites nearby, and all the major networks' coverage maps show full 3G/HSDPA coverage there, so I guess I just have to try it and see.
To be honest, the reports I've read so far of the various networks' performance are all universally terrible. I can but hope that only the worst is reported, and that it's not universal. Obviously performance depends on location (which will be fixed).
They all seem to be the same price for PAYG 3GB, so I think I'll try Three first (thus hopefully avoiding most of the iPhones and Crackberries) and if that's [censored] I'll take it back and try something else.
I don't know for certain about the phone line, but obviously if she CAN have a real line then I will just keep her on DSL, but that would get ugly as she's getting a temporary room at first and moving to a better one when available.
As long as we can still do reliable webcams... that's all she'll want.
Thoughts on the "always on" thing still welcomed, please!
