My sister has discovered some serious downside to not having a landline: international calling plan. As a result I never talk to her because it costs her a mint to phone me. Since you pay to receive calls in the States on your mobiles having me phone her is no better.
Aside from that there's the fact that she lives in earthquake country where losing main power to charge your phone for extended periods of time isn't an impossibility. I'd at least have a hardline phone (not a DECT) in a drawer for that eventuality.
I live in earthquake country. Apart from the most minor of tremors and aftershocks, we haven't had a lot of earthquake action in the five years I've been here... and certainly nothing that would knock power out. If I may ask, (assuming she's in the US) whereabouts is she?
