That network makes me sick and want to barf. But if I barfed, they could analyze my stomach contents (with smell sensors) and see what I ate for breakfast. And if I had eaten shawarma, they would come for me...
Wow, mylar, I'll have to try that out.
I heard the second battery is just a decoy. The thing you really need to worry about is the high farad capacitor camouflaged as a button. (Its usually the thick button with extra wires going to it.)
One time I turned off 2 cell phones before entering another country by plane. Upon entering the country they both received texts from the local network with advertisements about the network. So not only did they turn my phones on, they also sent me crap...and logged my cell into The List.
