Excellent Function 

This app provides detailed information on the nearest networks and even allows you to provide your own information to aid your search.

With CellMapper, you can obtain advanced network information using base stations in your area and map information provided by other users. Through this app, you can access information on networks such as GSM, CDMA, UMTS, LTE, and LTE-A.

On the main screen, you can see data on nearby network coverage. You can also access maps within the app for more information. These maps allow you to browse locations around the world, but the key is to select the service provider whose coverage you want to view to clearly see their coverage status.

CellMapper is a great tool that provides you with detailed statistics on nearby available cellular network coverage. In addition, the app offers calculators for different frequencies: GSM ARFCN, UMTS UARFCN, LTE EARFCN, CDMA, and iDEN.
