Aio Wireless, a wholly-owned subsidiary of AT&T, has announced the launch of no-annual contract LTE service covering more than 200 million people. Aio has also added Naples and Ft. Myers to the number of markets it serves.  Aio began operations last month in Houston, Orlando, Tampa, Jacksonville and Gainesville, Fla., and plans to expand to additional markets across the United States over the next year.   

Aio also announced today the expansion of its LTE-capable device offerings with the addition of the ZTE Overture which will be available in the next month.  Aio is offering three simple rate plans, ranging from $35 to $70 per month.  All three plans include unlimited talk/text/data with a pre-established amount of 4G LTE data access.  

Company has made the transition to 4G LTE easy for its customers by sending a free over-the-air software push that has automatically upgraded their SIM cards so they can access LTE services when using an LTE-enabled device in Aio's LTE footprint.
