How Does It Work?

CEL-FI mobile signal boosters improve signal between a mobile phone and a mobile network tower, allowing you to have clear voice conversations and a stable data connection.

An external antenna collects the best mobile signal from outside and transmits it to a CEL-FI mobile signal booster unit. The unit strengthens the signal and rebroadcasts it through an internal antenna inside the building or vehicle.
