I'm going on holiday to America with the family soon, and I can see us splitting up now and then while we're there, so we'd want to call each other's phones occasionally without spending a fortune doing it.
I'm guessing that doing this, normally the call will have to bounce from the US to the UK, then back to the US again to the recipient, which will probably cost a bit. (Please tell me if I'm wrong and the call stays in the US and costs the same as calling in the UK since that's where both the sender and receiver phones are located)
I don't know much about this kind of stuff, but I'm guessing the best thing to do would be to get a sim card for each of the phones that would use one of the American phone networks. I had a little read up on this, but I'm not convinced this would work. Does anyone have any input?
There are 5 phones of a variety of ages (pre-bluetooth to modern), and most are on O2 pay as you go.
