The HWg SMS-GW3 is a central 2G text SMS gateway for use with compatible environment monitors connected to an Ethernet network. The SMS-GW3 can send SMS alerts and dial pre-set phone numbers specified in the device or the HWg-Trigger software application. The SMS-GW3 requires a SIM card and can be accessed by any of the compatible monitoring devices (see Related Products) on the same Ethernet network at a Box-2-Box level, to allow a single gateway for SMS messages and phone alerts.
