[Xymon] State of the art SMS alerting?

Can anyone shed light on the current 'state of the art' for alerting by SMS from Xymon? Are there recommended usb-modem/software combinations to achieve this?

I'd like to have the option of sending alerts from my Xymon server without relying on email->SMS gateways. (When I need to announce that the mail queue has reached critical, it seems foolish to try to dispatch that alert by mail.)

I'm running Xymon on Solaris which will ultimately limit my options, but I'm interested in any information you have to share.

Do things because you should, not just because you can.
