Phone plans start at $55 with 2GB of data, tablets start at $15 for 250MB

AT&T has just announced that its separately-branded prepaid service called Aio Wireless will expand to be available nationwide starting in mid-September. The service, which is currently only available to customers in Florida, Texas, Metro-Atlanta and Chicago, will expand to cover customers across the country at an unspecified date in September. Not to be confused with AT&T's self-branded GoPhone prepaid brand, Aio Wireless offers lower levels of service and cheaper prices than GoPhone but also offers a wide range of handsets and BYOD options.

Aio Wireless offers a few different mid-range Android devices like the Samsung Galaxy Express and ZTE Prelude, but we're going to assume most will use these plans with their own device and a standalone $9.99 SIM card from the carrier. There are just two simple smart phone plans to choose from in either case — unlimited talk, text and data with 2GB of high-speed data for $55, or 7GB of high-speed data for $70 per month.

Following along with GoPhone's recent upgrade, Aio Wireless is now offering LTE data speeds to customers as well, which is a big upgrade for prepaid customers. The phone plan terms explicitly cap data speeds at 8mbps, however, which is not the case on GoPhone's plans in our experience.

Data speeds are slowed — rather than cut off — after you hit the given limit, and additional buckets of data can be purchased at the rate of $10 per 1GB if you want to top-up. Standalone tablet plans are also available, with the base price of $15 per month for 250MB of data.

If you're interested in browsing Aio Wireless' plans you can visit their website at the second source link below, but you'll need to enter a Florida or Texas zip code to browse until it opens up officially nationwide.
