How It Works

The cell tower antenna mounted on the outside of your vehicle reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster.

The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.

Your device gets a stronger signal, and calls and data are fed through the booster back to the network.

How to choose the best cell phone signal booster for your car, truck or RV

If you need a signal boost for one person in the front seat, select a Single User Cradle booster. The patented cradle holds your phone and boosts the signal.

If you need to provide a boost for multiple users in your vehicle, choose a Multi User Wireless booster. All these boosters support multiple simultaneous connections across multiple mobile carrier networks.
