SMS gateway on the contrary - where to get it?

Question

Telecom operators

Where can I find information and / or connect to the service "send SMS - it sends an email or knocks somewhere on http"?
Better second.
PS. To make it clearer, you need to manage the server using SMS, while there is no physical access to the server . Accordingly, there can be no talk of any whistles.

Answer 1

I have not seen such services, but such functionality is implemented elementarily. Buy a Huawei 4G modem, insert a SIM card with internet into it. Further in the browser, you can open the modem's admin panel and view or send sms there - the key point here is that everything happens in the browser.
Then you just have to create a custom script that will monitor incoming messages and, depending on the command, perform the necessary actions.
You don’t need to know anything except JavaScript here, write everything yourself or order a bot (extension) from someone who understands. Finally, I’ll add that I personally used such a scheme more than once for mailing lists - there were no problems yet.

Answer 2

Any Sent SMS message must be received on something. The easiest way to do this, as you have already been told, is with a modem. You don't need any LTE, just GSM and a simple script that will check the presence of SMS with AT commands, and if they appear, send an email. You can even stick this into some Rapsberry.
From services as a variant of IFTTT (True, you need a phone with a SIM card), and indeed a lot of things are googled for sms to email ( tyts ).
