In addition to announcing a trio of new Android tablets, AT&T has also announced that it is expanding its GoPhone prepaid plans to support a handful of tablets, including the iPad mini and iPad 3. The GoPhone plans work by purchasing a $10 GoPhone SIM Kit then choosing a pre-paid data plan for your device. For $15/mo you’ll get 250MB of data and 100MB of additional data can be purchased for $10 each. $30 a month will get you 3GB and 500MB of additional data will run you $10. Finally, $50 per month will get you 5GB of data, with each additional GB costing $10.

You can read the full list of compatible tablets on AT&T’s website. It’s odd that the iPad mini with Retina and iPad Air aren’t compatible with those prepaid GoPhone data plans. Most likely, however, it’s due to AT&T wanting to keep the GoPhone name associated with older and lower-end devices. With the recent deals we’ve been seeing on the iPad mini, it’s looking more and more appealing each day, especially when paired with somewhat affordable data.
