what's the alternative for something straightforward like that?

A raspberry pi with a 4g hat?

Overkill I suppose, in the past for similar stuff I've used a microcontroller with a GPRS modem, but since the 2g switch off I'm not sure it can be done that simply.

4g hats don't even work with many providers anymore since many US carriers are whitelisting only their allowed devices to send SMS on their networks.

There isn't one. This headache is legal, not Twilio

There is, it's called a USB 4G modem that plugs straight into whatever server you want.

Many carriers don't allow non-authorized devices like 4g modems to send SMS on their networks now. That's a recent change (last year).

So now you need a phone, maybe with USB Ethernet, and you write an app that exposes a REST API, and you call that?

Not a great solution, I guess, but ... zip-tie/hot-melt the hardware into a box with a fan and I guess it'd be mostly as reliable as a Raspberry Pi?

Is there a cheap Android phone with an external antenna socket still?
