The Multitech Multimodem GPRS model MTCBA-G-EN-F4 has an ethernet
port. Add a SIM card from your favorite wireless carrier and you can
send and receive SMS messages via "AT" commands over a TCP socket.
Problem is, it seizes up or otherwise founders every few weeks and has
to be power cycled.

Has anyone heard of other products with a good reliability record?

Any pointers on this would be greatly appreciated. I have a need for
geographically redundant access to the same phone numbers in order to
send and receive SMS messages. Even if I have to buy a pair of T1s
that are 99.9% idle, it'd be worth it.
