Heya folks. I want to attend protests, but they are going to happen fairly far from where I live: to the point where it might be harder for me to navigate without access to my phone. I saw a post today that there are Faraday bags you can get to stick your phone in, which will prevent cops from picking up my cell data. Do you all have any recs or experience with these?
Edit: Thank you all for the recommendations!
It doesn't exactly answer your question, but there are a few phones with hardware switches that will physically disconnect power to the modem and all the other radio components. They aren't exactly amazing, as far as phones go, though.
