Republic Wireless to launch $19 unlimited voice, SMS and data service

Gigaom - For those who have played around with the combination of Wi-Fi and voice calling known as UMA, the idea behind Republic Wireless is no different from the Unlicensed Mobile Access (UMA)-based service bundled in some T-Mobile BlackBerry devices. T-Mobile also has UMA available on some Android phones. When inside the office or your home or inside a Wi-Fi hot-spot, all phone calls and text messages are sent and received via the Internet. When there is no Wi-Fi, the calls are routed over a cellular network.
