I found sources explaining how to send SMS
You can install chat in hass.io doing:
apk add ppp
So I figure out how to fix the error “Can’t get terminal parameters: Inappropriate ioctl for device” discussed here
Turns out that chat is trying to read the response from STDIN, but in the context of Home Assistant this is incorrect as STDIN contains the message we want to send. It is also incorrect in that chat wont be able to verify if we got the correct response from the modem (e.g.: “OK” )

I found a suggestion for a GSM module in
Should be easy enough. You can use a battery backup ups unit for the router and the pi. Then use a router that has cellular interface as a wan. I use peplink routers and they make this trivial. Then your only question is if you want to pay for the monthly cellular modem bill for something you may never use.
the Adafruit FONA - Mini Cellular GSM Breakout - SMA Version [v1] ID: 1963 - $44.95… but I need 4G as well. There are suggestions to use a LTE Surfsticks what can be bought on Raspberry Pi - Wireless im Pi-Shop.ch as the actual mobile network module is not cheap 4G / 3G / 2G / GSM / GPRS / GNSS HAT für Raspberry Pi, LTE CAT4

So what is the smartest option?
Connectivity gets me to the next point. How can I ensure that only very little data is sent to an outside central HA instance what records other places as well?
