Their web site says there are no annual fees and minutes never expire. They have many countries with free incoming calls and I don't see surcharges or connection fees to make a call. The rates to call back to the U.S. are not bad. Their $48 Travel pack has $40 of airtime. It is an Estonia phone number. So what am I missing? Is there a better deal out there?
