TJ’s Weblog reports on United Mobile:
"United Mobile is a licensed Mobile Virtual Network Operator and provides worldwide mobile communications services with its own network infrastructure and SIM cards.
United Mobile has developed a revolutionary technology, eliminating expensive roaming costs. United Mobile offers free incoming calls in 80 countries and international outgoing calls at worldwide low rates."
I haven’t heard about United Mobile anywhere else, but this seems like a no-brainer if you are a world traveler (I have gotten some crazy bills just roaming in Mexico).
