Review on 📵 Waterproof Signal Blocking Nylon Smartphone Faraday Bag with Quick Access - Device Shielding for iPhone, Samsung Galaxy, and Most Phones - Travel, Privacy, Anti-Hacking - Available in Multiple Colors by Juzer Rashid

This is the best way to get rid of annoying automatic calls, in our opinion. We put the phone in our pocket, turn the valve and everything is just.silent. Both of our phones fit in at the same time, making it a lot quieter. Since most of the calls are from people trying to sell us something, we check our voicemail every few days. The phone company stores our text messages and sends them when the phone can receive them, so latency isn't an issue. We can't tell if the GPS locator is blocked, but nobody told us they used it to find us, so we suspect the signal is blocked, as are the phone calls.
