AT&T has announced the addition of pay-as-you-go data plans for its international data today, updating its DataConnect Pass options for laptops and netbooks. Packages include $25/20MB, $60/50MB, $120/100MB and $200/200MB deals. It’s still relatively expensive, but still cheaper than paying for each individual instance of usage. Plans can be scheduled to start at a certain date for folks who already have sorted out their travel plans. In order to not be caught out at the last minute, users are also warned with a free text message and email if they’re close to running out of the allocated bandwidth. AT&T had already been offering prepaid data in the US, but roaming data has only been available to phones on subscription.
