Open Signal Cell Tower Locator 4+

Does not work as advertised.

Not worth paying for a subscription.
The arrow points toward my nearest tower confirming the free WeBoost app test.
But, the map returns an ‘Unable to process server response’ error message, so the map shows a blue dot where you are located, but no info on towers.
I’m using an iPhone 15 Pro, IOS 18.3.1 on the Verizon network.

This is one of the best apps out there

Next week I’m gonna buy the full year subscription there are a couple more things that should be added to this app put all this later after I enjoy the full experience of it but overall everything that I’ve seen it’s a great up everybody who’s giving it one stars it’s obvious that you’re targeting this app this guy worked hard to make it nice and it’s a nice that gives lots of details probably details you don’t like that’s why you’re targeting a lot of these apps on here so it’s not just you the guy behind this app they’re targeting all the apps like this cause someone’s trying to hide a lot of these stingray towers keep up the good work your apps are saving a lot of peoples lives who are being targeted thank you & don’t listen to any of these people seem like a bunch of lowlifes
