How to use CellMapper to find the best carrier coverage

CellMapper is an app that uses crowd-sourced data to help users find the best mobile network coverage by mapping cell tower locations and signal strength. Although it can be overwhelming for new users, it provides valuable insights into carrier performance in different areas. This tool is particularly useful for deciding if upgrading to a new phone or switching carriers is beneficial based on local network support for advanced technologies like 5G.

The app requires users to contribute data, which enhances its accuracy over time. Users can view coverage by different carriers and network types, and detailed information about signal quality and bandwidth at individual towers. While CellMapper does not allow direct comparison between carriers within the app, it provides enough data for users to manually assess which carrier offers superior coverage in their area.
