AT&T announces two new international data plans for iPhone

For U.S.-based travelers who spend a lot of time abroad, the iPhone can be a useful device to carry—but getting online around the world is an expensive proposition. AT&T is now rolling out a pair of new international data plans to join its existing offerings। The two new plans will be available beginning Wednesday.
Whether or not these new packages will actually ease the strain on globetrotters’ wallets remains to be seen, as they’re a bit on the pricey side. The lower of the two runs $120 per month for 100MB of international data while the higher goes for $200 month for 200MB—and that’s on top of your existing domestic plan. On the upside, those with commitment issues need not fret: you can add or remove the international data package from your plan at any time.
There are some additional restrictions, however। For example, the plan applies only to 67 countries. In other places, you’ll need to pay between $0.010 per kilobyte and $0.0195 per kilobyte in order to use your plans. A full list of countries is available on AT&T's website.
