People that work in classified environments. You can’t have smart devices (phones, watches, anything that communicates with the outside) while in these controlled spaces. pagers are acceptable because they’re 1 way communication, so there’s no risk of data leaks from the classified space
Idk man, I have a federally compliant 1 way pager. So it’s not illegal. We score the highest marks on our DoD security audits every year. Theyre distrubuted from the security office, so I’m sure they do some sort of vetting on each individual one.
We’re a govt contractor, but our civilian govt counterparts use them too
