Cell Phone Towers World Map

I don’t know why this app has a low rating it’s found every single tower around me I recommend a download it if you’re looking for the cell towers around you also my only question is when you click on the tower from tower location it gives you a bunch of numbers that look like call signs does anybody know what those numbers mean?

The app looks great, really like the design and features, however the data does not appear to be accurate. Of the 3 towers it shows near me, 1 is a horseshoe pit, another is a AC unit and the third is an empty field that I walked through to confirm. The compass is way off too, perhaps that is why the data doesn’t appear correct. Or these are towers in a different dimension.

Worked as expected in the US.
