I have an application where I want to send an SMS, probably
once a day, from a remote system. I want to be able to connect
a cheap old handset with a PAYG SIM to a PC and install the
lot in a rural location -- where there is GSM coverage.
The handset and the computer that drives it would run off a
lead-acid battery and a solar panel, probably for weeks at
a go, unattended.
I'm looking for pointers to a cheap old handset model that can
do GSM1900 and that has an accessible RS232 protocol for sending
SMS messages under computer control.
I've had a quick look at the gnokii software that I could
use with a Nokia 5190 or 6190. Are there newer handset models
that are readily available used, for cheap, that sup****t a more
straight-forward protocol, like the "AT" commands? What should
I be looking for?
