We just returned home from Russia and tried to use a phone card with pay phones -- and found it frustrating. We are thinking about getting a cell phone and have seen two that seem intersting. One that Rick has mentioned before (or at least his name is listed on their web page) is Mobal and the other is Telestial. The Mobal rates are much more expensive, but sometimes you get what you have paid for.
Have any of you had experience with these two phones?
