Thanks.
External Router: "Globsurfer III" you can send SMS from its cofiguration page. With a modem, you can ask someone here having a 4G modem if it has the extended AT commands that your program need. But what are these commands? I do not know if they are standard. See for example here: http://www.smssolutions.net/tutorials/gsm/receivesmsat/ http://www.smssolutions.net/tutorials/gsm/sendsmsat/ Perhaps you can write your own script with expect: https://www.tcl.tk/man/expect5.31/expect.1.html Rodrigo.
