It’s been a few years since I was inside iPhones regularly but back then… All of them had a physical antenna or two which plugged into a board on a little coax connection.
Unplug those, no reception, phone just assumes it’s in a dead zone.
WiFi would still work if enabled. Which probably means they could find you via WiFi even if switched off in the current world
Cellular typically uses a separate antenna than wifi, on a smartphone i imagine they’re directly on the wireless chip instead of a daughter-board? Laptops and bigger stuff usually routes the antenna wires to the back of the lid, behind the screen, im more used to that
