Sending SMS and ring out alerts by HWg devices or other 3rd party software

The HWg-SMS-GW3 LTE is a central SMS gateway that HWg devices and other 3rd party applications (e.g. PRTG, Nagios, http) in the same network can use to dial numbers or send SMS alerts. Target phone numbers are specified in the sending device or the application.
The central HWg-SMS-GW3 LTE gateway significantly saves costs of external GSM modems as the entire installation only needs one SIM card. Neither additional software nor internet connectivity are needed.
