I would use something like that.
I'm thinking of building a Pager with the pygo2 once it finally hits the market: https://pycom.io/product/pygo2/
It's got LTE-M which is perfect for this, and LoRa and SigFox as backup. A year's service is about $40
Unfortunately it's not untracked like the old pagers were but in return it should do confirmations and even replies somehow. I'll have to add a beeper/vibration motor and a stronger battery perhaps but I think it'll work.
The issues other people are describing with insecurity and lack of ack could also be resolved. The backend server that accepts messages could even support WCTP for backwards compatibility.
