One would hope that a doctor on call would monitor their pager/cell phone to ensure they have service.
I know when I was on pager rotation, I was very aware of when I lost service, and governed my location accordingly.
Actually, I'm not on Internet Operations Pager Duty anymore, and I can _still_ tell you that the Old Spaghetti Factory in Redwood City results in my iPhone losing Data - I get very nervous while I'm there.
Net-Net - the doctor argument doesn't hold water, there are a ton of other reasons why you might lose service beyond a theater jamming - and you need to be aware of all of them and take appropriate measures.
