Welp,, I'm not sure what you are referring to but I will say that any object you place between your phone and the outside signal adds attenuation. A signal can only take so much attenuation before it is unusable.
Here's one marketed towards law enforcement officers. The idea is that they can use the phone without it having any GPS/RF/etc signals going in and out, thus preventing remote wiping, tracking, etc.
"Disklabs Faraday Bag is an enclosure formed by a multi-layered conductive mesh, coated in a rip-stop nylon, (the same material that parachutes are made of), then covered in a polyurethane outer skin to ensure the product is robust and fit for purpose."
Seems dodgy. They don't list attenuation value and the line "Wait 30 seconds" is laughable. RF travels pretty much at the speed of light so in 30 seconds , and given infinite energy, RF could travel 5,580,000 miles.

Do those Faraday cage phone cases/bags actually work?

Do you have a link to one of these items?
