I'm trying to find the best way to avoid (as much as possible) the cost of internation calls when abroad. at the moment we're off to the USA and so I'm looking at that area to avoid costs.
The best Idea I could come up with was to find a Windows Mobile, Unlocked... A US Pay as you go sim card with good (hopefully free) internet time... install skype on the phone and use that to connect to the world.
I've yet to find a sim only package on a US mobile phone provider however, has anyone come across one? Or has a better idea?
