Know the instant your network switches between 5G, 4G, 3G, or 2G
Frustrated by silent drops from 5G to 4G? SignalSense alerts you the instant your network changes – giving you the power to pause downloads, save your data, and avoid unexpected charges.
SignalSense continuously monitors your mobile network and notifies you whenever your connection switches between 5G, 4G, 3G, or 2G – helping you identify network issues before they affect calls, streaming, gaming, or downloads.
