@nRiTeCh try wrapping phone in aluminium foil with overlapping folds. Wait for a minute or more for the phone to lose signal.

I dont have foil but tried keeping phone in aluminum kitchen utensils with multiple vessels on one another. Bad luck the phone still rang.
So I wonder if the pure aluminum vessel layer idea doesn't work then how come aluminum functions to block signals?

Everyone these days knows that its an app trick to reject their nos. I simply want them to know that I'm not in coverage.

Take 2 numbers, forward their calls to each other and see and what happens.
