Review: Mobile Phone Service while abroad

Sim Cards

While preparing for a trip to Europe this summer, I spent quite a bit of time researching various options for international mobile phone service. Unlike past trips out of the US, where I mainly stayed in a resort, this time I wanted access to my smart phone's GPS and mapping apps. Between my traveling companion and I we had three devices we were planning to bring, an AT&T iPhone with their Passport package enabled, a T-Mobile iPad with it's free international data and a OneSim Card in an unlocked iPhone.
