Rx Monitor provides real-time display of mobile network information that the phone communicates. Basic network information, call and data statuses, received radio signal from cell sites are included. Clicking on displayed information produces help dialog explaining many terms and acronyms. Cell information works on all technologies: GSM, UMTS, LTE, NR. Showing cells' frequencies requires Android 7.0 or newer. NR requires Android 10 or newer.

Newer Android requires location service to be enabled for before cell data can be displayed.
