Do what I do Adey. Last thing before heading for the tee is check my mobile phone. No calls, then pop it in the boot of the car. Play my round and take clubs back to the car. 4 hours or less (hopefully). Check phone. Any calls? Reply to them before heading into the bar. No calls? Leave phone in boot of the car. Check it again when leaving the bar to drive home. So 4 hours if the maximum that I've been "uncontactable".
This is tough subject smiffy. In 20 years of playing I have never needed to be contacted that urgent on the course, but last year I had not gone golfing as it was mothers day. Now if I had been on the course then I would have received a call of up most urgency while playing. Not getting that call for another 4 hours would have been an absolute nightmare.
