CellMapper: Your Comprehensive Cellular Network Information App

CellMapper is a powerful application providing detailed insights into 2G, 3G, 4G, and 5G (NSA and SA) cellular networks. Users can actively contribute to crowd-sourced coverage maps by sharing their collected network data. The app boasts advanced features including low-level network information, frequency band calculations, and dual SIM device support. While data processing may take a few days to appear on the app and website (cellmapper.net), the app offers immediate feedback after upload. Note that the app requires permissions for location access, network status, internet connectivity, and phone call management, with additional permissions for specific functionalities and backward compatibility with older Android versions.
