AT&T’s second touchscreen LTE mobile hotspot, the Sierra Wireless device called Unite, was announced today just four days before it is available for purchase through all conventional AT&T channels. With a 2.4″ touchscreen display that prominently features data usage and Wi-Fi information on the home screen, Unite is primed for customers looking to expand their wireless connections beyond the traditional grid. The device boasts 10 hours of battery life with regular use, along with ten days of standby, for customers who need the device for long stretches of time away from the desk. It’s just one way to stay connected on the go, and for $0.99 represents AT&T’s attempt to bring its LTE and wireless plans to the budget-conscious marketplace.
