This story is about Stingray devices or IMSI catchers. I started noticing I was unable to get 3G/4G on my phone and my coworkers seemed to know my business. At first I thought my phone was hacked. I got a new phone and was careful to not let it out of my sight yet still noticed the oddness.
I ended up downloading apps that tell you the Cell Tower ID you are attached to. Signal finding software to help find good places for signals. I quickly noticed at work and home the Tower ID was along the lines of 000000. I showed someone I was suspicious of and it all went away. Basically they were trying to make me think I was crazy and anyone I know. With pictures and proof I started turning the tables and got my life back.
The point is this story is not just theory. If you might be in this situation the apps name is Network Signal Info.
