Fake phone towers are used to catch calls and textmessages in real time so it doesn’t protect against that either.
These bags only protect against exploits in the call/sms/wifi/bluetooth protocols as long as they are in the bag. Which you can also just protect yourself against using hardware toggles, and in some cases even software toggles.
Can’t have a World News thread without some Americentrism right?
