National Geographic will start selling a the travelphone and plan next month…there’s no content involved, just the ability to use the phone in over 100 countries, reports CNet. Outgoing calls will cost 90c per minute, which is pretty steep but stops you having to worry about getting a mobile when you’re travelling—and there is no contract. It also draws on NG’s image as a globetrotting company (Lonely Planet is the only other one that springs to my mind).
