The Sure Call SC-NRANGE2 N-Range 2. 0 Cell Phone Signal Booster installs in 3 easy steps and increases voice, text, and 4G LTE for a single device inside any car, truck, or SUV. Using just 2 components—the N-Range outside antenna and an upgraded phone cradle with built-in antenna—N-Range has revolutionized the vehicle signal booster to keep drivers connected to very distant and hard to reach cell towers. N-Range 2. 0 boosts all cell carrier signals in North America using Extended Range Technology (ERT) to capture, amplify, and transmit the improved signal more effectively than any other booster on the market. For a single device in very weak signal areas, there is simply no better cell signal booster to maintain connectivity for calls, texts, and data streaming.
