Here in VN, SIM based phones are easy to use. It seems that in the US they work very hard to make them impractical. What I would like to find is a SIM card that works in the US... and doesn't expire in a very short time period. In particular when I return to the US after say a year on the road... i just need to be able to make a few calls like calling a hotel shuttle, or making a reservation... I don't want to pay $30 a month service fee just to own the card that sits in my suitcase ... basically I want one that works just like VN SIM cards... Anyone know of any?
