OpenSignal app lets you check whether Verizon, AT&T, Sprint or T-Mobile has the best 4G LTE coverage in your area

Choosing the right carrier could be a difficult task: you've probably all seen the alluring new offers by T-Mobile, and Sprint has also been improving its network a lot lately, but will these two carriers provide adequate coverage in your area? And what about AT&T and Verizon Wireless, which one has better 4G LTE coverage?

Those are essential questions that you will want answered before making your carrier choice, and they are particularly important if you move to a new place, where you don't know that well what areas carriers cover.

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.

It is a very useful app. I have tried it on my iPhone but not on my Android phone.

It is similar but more buggy as would be expected.

According to the app, there are no towers anywhere in my state. My phone must be magical then!

Or the signals are penetrating your state while the towers are outside your state? Presuming what you call a state is a relatively small portion of land.

No, I live in the US, as in the United STATES of America. I live in is South Dakota, it''s just over 77000 square miles of land, so no not a small portion of land. On their app I went out to roughly 90 miles all around me and no towers shown, even though I know there are roughly 6 towers within a 30 mile radius. Finding nothing their I went to the largest city in the state, knowing full well from my time living there that there are around 100 transmitters and towers in the metro area handling multiple carriers, and nothing shown.

In that case, there's definitely a problem with the app, might want to live a 1star review pointing that out...

I use this app professionally. Prefer it over root metrics and the others.

In my city, the system (at&t) is overloaded. Constantly get 5-10 meg down, 30-40 up. When I go to another city, down & up are in the 30-40 meg range.
