When my nephew went missing earlier in the year he had has phone with him, but it was switched off. It took several hours before the phone pinged a tower (although he was also travelling through an area which may have had poor coverage).
The impression I got (second hand) was that phones that are off still ping towers but much less frequently (less than hourly) than phones that are on and that the police have no trouble getting the information in near real time when searching for missing minors. No idea of the make or model of the phone but not a smart phone.
