This is goodin the event of isolation of a location from any IP connectivity to a carrier gateway.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?
That is shocking.I have had a fantastic track record with a Maestro 100 GSM modem with a serial interface.
One of my customers has one powered on for about a year now, and it's never missed a beat.
They apparently support TCP/IP and the datasheet mentions something about email, but I have no idea what that really means, and don't really care so much.
I send it standard GSM AT commands, and it just works.I've done the whole old nokia handset thing in the past several times and it's *ok*. Now though, I say don't bother, this thing is maybe a couple hundred dollars, and saves you oodles of time fooling around making it work reliably.
