Aluminum foil works. At least, I can’t receive calls or texts through it last I tried.
Get the heavy duty kind. It’s not any more conductive, but is more durable against tearing.
Note that a gap in your phone’s tracking data can look suspicious at times. Sometimes it’s less suspicious to leave your phone at home.
Just want to note here that suspicion does not equal proof. Consider honestly what you are trying to accomplish, and what the risks are. There are absolutely scenarios in which even raising suspicion is unacceptable, and others where it isn’t.
I’m not selling dope, I just don’t need Google knowing everywhere I went on the way to the doctor’s office, where I’ll probably sit and look at cat videos in the waiting room. I have anxiety and I can’t stand surveillance like this constantly.
Then yeah, faraday bag will suit your use case :)
I second this. I’ve seen videos of cell phone thieves getting caught and they all have rolls of aluminum foil on them. I trust they know how to effectively block wireless signals.
Getting caught? Can’t work that well then!
jk
It’s not any more conductive
quick note: you’re likely correct the conductivity may not be higher, but the conductance likely is.
in other words, i second your suggestion of heavier duty foil (for EM reasons, skin effect etc) alongside the mechanical factors you mentioned.
Are you trying to EMP-proof your phone, or block signals/tracking for a time?
I just want it to not be tracked constantly.
SLNT Faraday stuff is supposed to be good. I’ve never used one. Michael Bazzell recommends them.
Does a microwave work?
From what I heard you won’t find a real Faraday bag that works well and blocks almost all signals, those found on Amazon are really not that effective and only “military grade” bags could be useful in these kind of threats
Okay. That means I need to chexk the surplus stores. Maybe I will get lucky.
I don’t think that if real Faraday bags meant for military work they are avaible in surplus store for civilians
This is not bleeding edge tech.
I know but don’t think you could find them there. The only way of getting good ones is surely to buy some that seems reputable (aka not amazon shit) and test them in labs (maybe someone already done that and that Faraday bags recommandations exist online)
Does a microwave work?
Use an SLNT bag
Something meant to maintain a high or low temperature. A Thermos or pizza delivery bag or a bag for bringing frozen groceries home. Some might just be foam, but there are also ones with metalic coating or a steel shell.
