Wrap your phone in aluminum completely for EM Frequency shielding when you want to make absolutely sure no one is listening to you or visually watching you.

Test it.

With your phone on … wrap your phone in Aluminum and try calling your phone with another phone.

Zip. Nada. Nothing.

Shielding. It’s Physics.

(Wrap yourself completely in aluminum, more than a tin-foil hat. Now you’re safe …Kidding … kind of 😂👍)
