AT&T announced today a new international plan for iPhone users.

A new $60 Data Global Plan will provide iPhone users 50 MB of data per month to search online, check email and access other information in 29 countries, including Canada, China, Mexico and areas in Europe and Asia.

The plan cannot be purchased separately and is in addition to the domestic plan needed for iPhone activation. iPhone customers that go over the 50MB limit will pay an additional $0.005 per KB in those countries where the plan is available. In other areas users will pay double the amount.

iPhone subscribers who want a smaller plan, AT&T is offering 20MB for $25 a month. The same rate applies for going the limit in countries covered by the plan.

AT&T says that international travelers should check their wireless options as part of their trip planning process. Travelers can visit the international page for details on where the service is available.
