CellMapper

CellMapper displays advanced GSM/CDMA/UMTS/LTE/LTE-A cellular network information and can also record this data to allow you to contribute to our crowd-sourced coverage maps. CellMapper works on both tablets and phones running Android 2.3 or higher. Features - Displays low level cellular network information data along with frequency band calculations (for some providers) - Reads cellular frequencies on certain Android 7.0+, Qualcomm based (root), Sony (root), and Samsung devices (root) - Displays a map of both coverage and individual tower sector coverage and bands - Supports Dual SIMs on Android One, Mediatek, Qualcomm, and Samsung Duos devices Note: The data on the site and within the app is generated shortly after it is uploaded. Locally calculated (less accurate) data is available instantly from within the app. Currently supported networks: - GSM - UMTS - CDMA (limited, many phones do not implement the API correctly) - LTE - LTE-A (limited, support on latest Samsung Phones with FieldTestReader) To start contributing, simply tap on the "Upload" button on the main screen.
