I warn you this (probably) isn't exactly what you're looking for, but
I've stopped using the SMS email gateways due to reliability issues and
when things are really going bad -- rate limiting. Instead I've moved to
sending my notifications through Pushover.net which sends (fast!!) push
notifications to phones.

You can send messages two ways: their email gateway, or write a
notification script that uses their REST api. It's very simple. I wrote
this in a few minutes and haven't looked back.
