Comment Finally gave up my pager... (Score 1) 635
... but only because I changed jobs. As part of the radiological emergency response team at a nuclear power plant (Watts Bar), I was required to have a pager on during my duty weeks. They were in transition to an email and SMS-based system (which they were using for non-REP response primarily and in addition to the pager system for REP) but that required regulatory approval from what I understand for it to become primary. It was an old-school, 10-digit motorola pager and the utility (TVA) owned and operated their own network towers.
