� What does it do exactly? If your mobile signal is weak inside your home or office, but there is a good signal outside the building or near a specific window, the device picks up the signal from outside and rebroadcasts it inside the location, to improve: * 📞 Calls * 📶 Mobile signal * 🌐 3G/4G data, and some CONNECT versions support 5G * Reduce areas with weak or no network coverage
