When it comes to using your cell phone abroad, international travel has gotten much less painful in recent history. Several U.S. wireless carriers offer more wallet-friendly international roaming plans than they have in the past, but there are always caveats and limitations.
For example, T-Mobile recently added free unlimited data in more than 100 countries for Simple Choice plan holders, but it’s only low-speed 2G data. If you want faster data speeds, it'll cost you $100 per GB — and those rates can climb even higher with other carriers.
