I guess it is possible. There is not real operating system, so no curl, but sending JSON is possible. That would be the interface to APIs mentioned by me anyway.
But then my question would be why would you want to have another SMS channel? I trust more the hardware modem then API over network. I would prefer other then already existing SMS.

I some more Push services:
* https://www.pushbullet.com/ 100 free per month, then 4 USD a month.
* https://gotify.net/ - Free and open source, needs self hosting on server. Has Android only app. I tried installation on my server. Just downloaded a package and run.

To tell you background, my intention was at first was to create an API to Telegram chat bot. This way gateway can send events to group chat. And maybe some time later also gateway is able to receive commands from Telegram chat (Old gateway was able to receive SMS from user to reply also via SMS). But the encryption required by Telegram is very strong, and sending a JSON takes around 12 seconds. Most of time the gateway is creating diffie hellman private key for TLS. Now I'm in investigation how this can be speeded up.
