Voyager Mobile has launched a new "worldwide" wireless service called Project Global Voyager, saying users on the plan "won't pay a penny of roaming charges." The brash new MVNO has only vaguely described how it works, saying that the technology is "completely network cloud based, with no special software residing on the individual handsets and devices." Though it hasn't revealed pricing yet, Voyager says the service will be available to businesses and consumers starting in 2013. Color us intrigued as to how they'll pull it off -- feel free to read the PR tea leaves after the break.
