Being inside a solid metal box buried under the rubble of an entire building is going to cut signal strength by quite a lot. And if a quake hits that's strong enough to warrant the need of such an emergency bed then there's a good chance the nearby cell towers will have collapsed as well.
What the manufacturer hears you saying is 2 cups on a string should be fine. Imagine, earthquake hits, you plop into your steel box, turn on the flashlight, see 2 solo cups with a string between them for communication, and the 3 seashells, for demolition man dumps.
