Bulk SMS services: how do they bulk send SMS?

I’ll make a reservation right away: you don’t need to redirect to intermediary services. The options for sending SMS through iron SMS gates are also not interesting.
I would like to understand how SMS mailing services work in terms of cooperation with cellular networks: there is some kind of SMS hub that a legal entity can connect to. Does a person or SMS mailing services enter into separate agreements with mobile operators to send a large number of SMS?
