Is there a phone case that blocks the phone from receiving any signal. Since my government in Canada has given itself dictatorial powers. Many Canadians might be now traced for peaceful protesting.
- dennis_jeeves1 5y agoI think the only safe way is to completely power off the device, or even better not to place it in a location where you want it to be detected at. For example do not carry it. Removing sim or turning on the airplane mode may not help because of various back doors, if any.
- istjohn 5y agoSee https://www.mattblaze.org/blog/faraday/ https://www.mattblaze.org/blog/faraday/: > At least in the frequency ranges I tested, two commercial Faraday pouches (the EDEC OffGrid and Mission Darkness Window pouches) yielded excellent performance sufficient to provide assurance of signal isolation under most real-world circumstances.

- post_break 5y agoYou can take the sim card out.
- mrlonglong 5y agoStill trackable through the IMEI number unfortunately. Faraday cages are the only answer.
- chipsa 5y agoInsufficient. The phone will still contact cell towers in order to maintain communication, because even a phone without a SIM can make a 911 call.
- mariodiana 5y agoIf you can remove the SIM, do that. If not, you could try wrapping the phone in two or three layers of aluminum foil, separating each layer by plastic wrap. YMMV.
