AVTECH’s GSM Modem
allows you to send text message alerts over any GSM/GPRS/EDGE
network from Room Alert Manager software. This compact 3G/2G modem connects directly to
Room Alert Manager’s host system by a USB 2.0 connector, which also provides power to the
modem. It requires a SIM card (mini-SIM), which you may obtain from your cellular service
provider.
