yes, a home-made Faraday Cage consisting of a star-foam ice chest wrapped in 4 layers of supermarket grade aluminum foil has been tested and with extra care and effort regarding the lid seal, it does indeed completely isolate a cell phone from RF signal interaction
am going to make more, but am going to shift the design over to cardboard box with manner of lid with flange and will order aluminum foil of thicker grade such that will require only one layer of wrapping (to save time in the process)
lot of people go with ammo cans, and that's a great approach - if you have some laying around to spare (mine I actually use for ammo storage), but they tend to be more spendy than cardboard boxes and aluminum foil (and foil tape); if I went with an ammo can, I'd also put an electrical non-conductor liner inside the can in which to house the electronics devices
