Earlier this year I think? I have a Twilio number that I setup just so my Home Assistant system could message me about things like water leaks. They stopped delivering any of those messages (while still charging me to send them!) and I have to register as a business and provide proof I have an opt-out, etc, etc.

The only phone number I ever texted was my real cell number, it's no longer worth having a Twilio number for a hobby project.
