Does anyone know the specifics behind T-Mobile's free international roaming? My wife and I will be traveling abroad to a few different countries this summer and rather than fumble around with getting a local SIM in each one, and then inevitably needing to re-up my credit on each one, I figure we can both get T-Mobile a few days before we leave, activate it, and then travel for two weeks without ever needing to pay anything more than the cost of a one-month T-Mobile family plan. That was the advice offered here, but I'm worried about T-Mobile's fine print, which states Does anyone know exactly how they measure that? Also, I can't seem to find the pricing plans for the add-ons that allow for continued 4G speeds abroad after using up the initial allotment, since I believe the speeds pretty quickly kick down to 2G when roaming abroad. Thanks for any help!
