Faraday bags pass through all frequencies smaller then the holes in the conductor.
If you want total blocking of all frequencies you need a solid conductive surface, i.e. a block of metal, or a bucket of ionized water.
So yeah, whatever you got, you need to test with the transceivers on the device.
But military grade is just gear porn marketing term, you can make a gaussian surface out of house hold aluminum foil for Pete's sake.

Thanks for the explanation
If you wrap your phone in aluminum foil that should block everything right?
sure, as long as there were no holes at all.
Cell phone frequencies are 2-20 inches so you could have one inch holes with no issue.
