I've seen a reference to his before; the receiver pays to receive mobile
calls in the USA? In Australia it's the sender who pays (of course).
And I believe that mobile phones (what you call cellular phones) don't
have their own prefix? We reserve "04" for that; at one time you could
even tell which provider it was, but now you get to keep your number when
you change providers.
But to bring this back on topic...

We had that in a previous $JOB; if Nagios (a general system monitor)
detected something that triggered a rule then a set of users would receive
a brief SMS, sent from a GSM modem. I looked at this for my own LAN, but
it ain't cheap...
