Back in the day (I haven't been in a while, unfortunately, so I don't know the current status), at nicer theatres and at the opera, they had a service available for emergency personnel (doctors, et cetera) where they'd take your pager, put a tag with your seat number on it (and also typically you'd be seated on an aisle), and they come fetch you if your pager went off. Worked great with minimal disruption to patrons... though the definition of "emergency" was fairly narrow, and this likely wouldn't work if patrons were insisting on it for family phone calls and so on.

It would work fine if this was a paid service. People could decide what "emergency" was worth being notified about. That would also give the theater some incentive to enforce a no-device policy.
