Product description

The SmoothTalker Mobile X1 50 dB mobile cellphone signal booster improves 2G/3G voice and data reception. The Mobile X1 is a plug and play wireless booster that does not require a physical connection to the cell phone or cellular data device, and boosts signal to all cell phones and cellular devices within the booster's range simultaneously. The amplifier incorporates dynamic adaptive gain control for powerful performance and brilliant reception. It features automatic oscillation control, and network overload protection to maintain maximum efficiency at all times.

The Mobile X1 captures the signal outside your vehicle and transmits inside the cabin. The booster will keep you connected when you are far from cell phone towers, up to 60 km or further depending on the terrain. It’s suitable for a car, truck, RV, or boat.
