I wouldn’t expect a modern pager to operate on the same technology as older pager. Pagers are a thing and they have there uses. I’ve heard of a physical pager being used to symbolize who is “on call”, and a team of engineers will pass the pager between themselves. I’ve seen restaurants pass out pagers to people waiting for tables. I’ve heard talk about some medical/emergency personal still using pagers. I imagine pagers are probably used in highly secure communications (military, statecraft), because the thing being paged doesn’t have to give away it’s location, or even the fact that it received the message.
