Sending SMS with router UMTS wired ethernet to S7 PLC

[Gustolo]

Hello everyone, for remote maintenance of S7 300 with Ethernet port, use the router umts RUT500.
Is very cheap and vpn support and much more.
It also has the ability to send SMS via HTTP POST.

SMS by HTTP POST / GET
It is possible to read and send SMS by using valid HTTP POST / GET syntax. Use the web browser or any other compatible software to submit HTTP POST / GET string to the router. Router must be connected to the GSM network When using "send SMS" feature.
Syntax of HTTP POST / GET string

http://{IP_ADDRESS}/cgi-bin/sms_send?number={PHONE_NUMBER}&text={MESSAGE_TEXT}

Note: parameters of HTTP POST / GET string are in capital letters inside curly brackets. Curly brackets ("{}") are not needed When Submitting HTTP POST / GET string.

According to you, you can send this command to the router via ethernet plc?
Thank you.
