AT&T Inc. (NYSE:T) today announced a new international plan that gives iPhone users 50 MB of data per month to browse the Web, check e-mail and access other information in more than 29 countries, including Canada, China, Mexico and in areas throughout Europe and Asia.

The new Data Global Plan is available to iPhone customers for $59.99 a month, which is in addition to the domestic voice and data iPhone plan they purchase during iPhone activation. The Data Global Plan enables international voice and data roaming, as well as international long distance dialing from the United States at standard rates.

The plan requires customers to first purchase a domestic voice and data plan for the iPhone and is not available as a stand-alone offer. Normal eligibility requirements for international plans apply. Should customers exceed the 50MB bucket in the 29 countries where the plan applies, they will pay $.005/KB. Outside those countries, consumers will simply pay for their data usage by the kilobyte, at rates starting as low as $.010/KB.

AT&T also offers a 20MB Data Global Plan for iPhone customers for $24.99 a month. The 20MB bucket applies to usage within the same 29 countries, with overage rated at $.005/KB. Outside the 29 designated countries, the data usage rate is $.0195/KB.

AT&T advises international travelers to remember to check their wireless options as a part of their pre-trip planning process.
