CellMapper - Advanced Cellular Network Information and Coverage Mapping for Android
CellMapper is a powerful mobile application that displays advanced 2G/3G/4G/5G (NSA and SA) cellular network information and allows you to contribute to crowd-sourced coverage maps. It is available for both tablets and phones running Android 4.0 or higher. With CellMapper, users can view low-level cellular network information data, including frequency band calculations (for some providers), and read cellular frequencies and bandwidths on supported Android 7.0+ devices. The app also displays a map of both coverage and individual tower sector coverage and bands, and supports Dual SIM devices. Additionally, it has a frequency calculator for GSM, iDEN, CDMA, UMTS, LTE, and NR.
It is important to note that the data displayed on the site and within the app is generated shortly after it is uploaded, and it may take a few days to appear. CellMapper currently supports GSM, UMTS, CDMA, LTE, and NR networks. The app requires several permissions, including access to device location and phone calls to gather low-level network data from the device. Overall, CellMapper is a must-have app for anyone who wants to stay informed about their cellular network and contribute to improving coverage maps.
