For Android users, there are IMSI detector application you can run to detect and defeat these sorts of devices.
The two most well known apps are AIMSICD. and Cell Spy Catcher.
This is also why it's important to not use SMS for text messaging as those are easily intercepted and parsed. Better to use a mobile messaging app with full end to end encryption like Google Hangouts or whatever your preference is.
Would you have a play store link available? I am not sure if I am looking at the same apps you're looking at.
I've been using Cell Spy Catcher (Anti Spy) for about 24 hours now. It takes 48 hours to learn your networks. I cannot say yet if it is any good. https://play.google.com/store/apps/details?id=com.skibapps.cellspycatcher&hl=en
I've heard good things about SnoopSnitch but have no formal experience with the app. https://play.google.com/store/apps/details?id=de.srlabs.snoopsnitch&hl=en
And about the Stingray, they have apps out there that tell you where the known cell towers are and how your signal should be relative to them. Wouldn't be hard to adapt one of those to an app that would tell you you're getting service from an unknown, and possible Stingray device.
Oops, someone already made one...

Contact your cell phone provider.
IMSI catchers are also used by criminals as well. Maybe they bought one off of a crooked cop or stole one.
Just because you're not doing anything illegal doesnt mean you're not as risk of connecting to a fake cell tower.
Download the app "Cell Spy Catcher" and talk to your cell phone company.

I've only messed around with "Cell Spy Catcher (Anti Spy)" but there are alternatives.
It's imperfect, but there's an Android app that helps avoid stingrays: https://play.google.com/store/apps/details?id=com.skibapps.cellspycatcher

If you're on Android try Cell Spy Catcher. That links directly to the play store. I'm unsure about iPhone.
This App will Help you in Detecting "IMSI Catchers" (also called "Fake Cell Towers" or "Stingrays").
For several years the FBI and Local Police have been listening to our Calls and Reading our Text Messages, using so-called "IMSI-catchers". One Example of such a "Fake Cell Tower" is the "Stingray", which is produced in the USA.
"Stingrays" are Mobile Devices that simulate Cell Phone Towers, forcing nearby Phones to Connect to them. They can Identify your Phone, and possibly listen to your Calls. Without having to put a Spy app in your Phone!
These "Cell Spy" Devices can capture Information from All Cell Phones within Range, including IMSI Identity, Location, SMS Messages, Call Logs and Call content. (IMSI stands for "International Mobile Subscriber Identity", which will Identify your Phone).
It is known that at least 53 Agencies in 21 States own "Stingrays".
Law Enforcement Agencies, Foreign Powers - and possibly Criminals - are using such "Cell Site Simulators" for Surveillance Purposes - without our knowledge.
"Cell Spy" Devices can be Hand-carried, or be mounted in Vehicles, Airplanes, Helicopters and Unmanned Aerial Vehicles.
During a Self Learning Process, the App will "learn" all Networks (Cell Towers, Base Stations) that are used by your Phone.
After the Self Learning Process - if this App should happen to Detect one of these "Cell Spies", you will be Warned by an Optional Sound and/or an Optional RED Screen. The simplest way to avoid being Listened In On, is then to turn off your Phone for a while, or at least to keep silent.
When the App Detects a Network that is not included in its Internal Database, it will Consult an External Database of Networks. If the Network is not Found there, it is assumed to be UNKNOWN.
Features:
How To Use:
After you have Opened the App the First Time, you should Start the Self Learning Process (which may take a few Days), and have the Phone with you at All Times - where ever you may be - in order for the App to LEARN about ALL Local Networks.
If you move to another place, you should Restart the Self Learning Process.
By using this App, you participate in the large collaborative community project "OpenCellID" - which collects the Locations of Mobile/Cellular Phone Towers, which now is a Database that contains almost 7 million unique Mobile/Cellular Phone Tower IDs. Use of this Database will increase the Probability of Detecting REAL UNKNOWN Cell Towers - and thus to Find "IMSI-Catchers" - and you can be an Active Part if it!
If you should NEVER Detect a "Fake Cell Tower" - you should consider yourself LUCKY - and NOT BLAME us!
Many problems seem to be caused by simple Misunderstandings. So if you have a problem - that cannot be answered by the FAQs Section of the App - please send us an Email - before you consider making a Bad Rating. Maybe we can help you.
