Huh... I had always imagined SCIFs were like faraday cages, so a cell phone wouldn't be able to send or receive any signals.

That would be prohibitively expensive in most cases.

O'rly?

These are not only Faraday cages, but they also actively transmit noise.

It's open information since the 70-ies.

A mobile phone will not work inside.

(OP here) I kid you not, the person whose phone went off inside the SCIF was holding his phone next to a window, complaining about the poor signal. He was some kind of scientist or engineer who had been given a clearance as an "expert" adviser to listen to and grade presentations by people like me. I'm sure he didn't usually work in a SCIF--this might have been his first (and probably last) time inside one.
