Can BP machines from the late 20th century send messages across provinces?

Good morning dear

Whether the BP function can cross provinces mainly depends on whether the base station construction of the paging station is adequate

And the BP machine cannot send messages at all. Also known as CALL machine, when someone calls the BP machine, the operator sends a text message with the XXX number calling you or some words that others say, and sends it to the BP machine, and then the BP machine calls back from the nearest landline

Think back to those days It’s so silly haha. Especially during the New Year and holidays, you can see people walking around looking for public phones with BP machines on the street. The public phones are full
