Dear all, I have a plc S7 1200 connected to my Rut241. Although I can read Sms from my Rut241 using my PLC I can not aend Smd. I tried testing the ability of the Rut241 for attending Sms by using the browser either with post get commands or from the router Gui. From the browser I receive a message stating "ERROR" and from the Gui I receive a message stating "Message successfully sent". In both cases no SMS is received from the Receiver cellphone. What should I check? I would like to add that when I install my Sim card to a mobile phone I can sens SMS with no problem
