A pager would also be constantly tracked via network triangulation.

No it wouldn't. Pagers as I used them received the same signals all through the country. The network didn't even know if the pager was on or not. It was purely one way. It supported numeric (and tone) and even text messages (not encrypted but this day and age that would be possible). You could be out of coverage but the pager would warn you and due to the low frequency and low bandwidth coverage indoors was excellent. The only time I received an out of range message was when I visited a cave system.

Transmitting pagers with sending and receipt confirmation did also exist at one time but that's not the ones I mean. Maybe a network will emerge again. It doesn't actually cost a lot.

I'm kinda hoping more people will want their pagers back for precisely this reason.

No, pagers do bi-directional communication just like phones. Even the old pagers from the 70s used bi-directional communication. They didn't just broadcast over the whole continent.

No they didn't. Most pagers were receive-only. In my country two way paging networks weren't even deployed. This is why they were allowed in hospitals and mobile phones weren't, they didn't transmit. Look up the POCSAG and ERMES protocols for example. All unidirectional. They didn't work on the whole continent, just per country.

Perhaps in the US it was different, I've never been there. But there they sure were unidirectional. Even the text ones. I still have several of them and I've run my own transmitter for them on the amateur band.
