To use properly GSM modem(s) to send SMS alerts, the modem should first be configured. In the related section of IPHost Network Monitor settings, please specify primary and/or secondary GSM modem(s).
The setup screen is self-explanatory; up to two GSM modems are supported. It is recommended to send a test SMS first to make sure the modem is set up properly and the alerts will reach the recipient. In case no modem data are available, you can discover available modem using “Find GSM” feature.
