Aio Wireless today added LTE 4G to its service offering. Aio Wireless is a subsidiary of AT&T and offers no-contract wireless service in the U.S. The wireless network launched in Houston, Orlando, Tampa, Jacksonville, and Gainesville, Fla., last month and today has expanded to Naples and Ft. Myers, Fla. Aio will gradually become available across AT&T's footprint around the U.S. over the course of the next year. Aio said that customers who already own LTE-capable equipment will receive an over-the-air update that adds support for Aio's LTE network. In addition to the availability of LTE, Aio also today announced the ZTE Overture, a new Android smartphone that will go one sale in July. The Overture has a 4-inch screen, 5-megapixel camera, front-facing camera, LTE, and support for memory cards up to 32GB. It runs Android 4.1 Jelly Bean, but pricing wasn't disclosed. Aio offers unlimited talk, text, and data plans that range from $35 to $70 per month to feature phones, smartphones, and tablets. In addition to the handsets it sells, Aio will also provide service to people who bring in their own, unlocked devices. Aio hopes to compete with other prepaid brands, such as Sprint's Virgin Mobile and T-Mobile's Ultra Mobile.
