You can indeed get any old nokia for $30 from trademe and add a ttl > rs232 level shifter (another $15 or so) to talk AT commands directly to the phone over serial, which will quite easily let you send text messages. I must say however that I've tried using sms in the past for outage notification with great failure. Getting a server outage notice 6 hours after it actually happened is rather annoying, but that was vodafone, are telecom more reliable? Is that a question I even need to ask? -Jon Matthew Poole wrote:
Hey JJ, why don't you go and work for a company where it matters if services are up or down, then let us know how your boat's floating?
SMS is a fairly common way of sending pages, since it's cheaper than getting a paging account through Telecom and then paying per page. That the device can be controlled by AT commands implies that it's a direct serial connection to a computer, so if that box is also the monitoring host the only thing that will stop it notifying of service or host failures is if it goes down itself.
So, how's that leaky boat looking now?

Well you got bigger issues if your net is down then sending out an sms don't you think? ,besides what if one of the internal switches or routers died and you couldn't get to the serial sms it's the exact same situation the fact is your still paying a lot more for the same service.
But hay try drill some more holes in the leaky boat eh..

You realise the purpose of the device is to notify them if services go down, right? How are you going to use your remote service when there's no net access? 'lol :):):)' indeed.

We've just been down this track at work.
Until now we have been using the X.25 network to send out SMS alerts, but yesterday we received a nice little cellphone black box with a serial interface, you can use it to send and receive SMS messages and you talk to it using modem AT type commands.
It's looking like a pretty good, and cheaper solution, and it will allow us to do more.
I can't remember the brand/model off the top of my head, but I can look on Monday if people want to know. From memory the unit costs $700 to buy and then there is just the standard cost of sending SMS messages.
