Why not wrap the phone in a couple of layers of aluminum foil? (Although, it won't shield against audio if that's being recorded even while an RF contact does not exist...)
The thread referred to refrigerators and microwaves. Yes even an ungrounded single layer aluminum foil bag with singlefold seam is able to block phones here. Test as desired. Unlike the former devices, foil is also light and easily carried for travel anywhere if battery is hardwired and/or you don't trust 'off' button. Also things like evercap and RF id/power may play in some devices.
