If I understand correctly, this means I'll need an extra SIM just to
send messages -- is that right? I build a Kannel server so that it can
talk to a terminal that is on the network and can send messages.

(It's an awful lot of extra hardware just for messaging capacity that
will only be used by a few users, though.)

What if I don't want to get my own terminal?

Can you show me an example of an aggregator?
