OpenSignal app lets you check whether Verizon, AT&T, Sprint or T-Mobile has the best 4G LTE coverage in your area
To help you make the right choice comes an app that you should know about: OpenSignal, available both for iPhone and Android. By using this app, you can see the coverage of every detail in your area in excruciating detail. Yes, you can see which roads and which areas are properly covered.
And while most people obsess over speed tests, lacking coverage can be a much greater problem, so we recommend you giving OpenSignal a shot to see your 4G LTE coverage.
