Not sure if you'll see this, but I stand corrected, just received a test alert on my new pixel 7 despite having those turned off. I used to not receive those (or they were at least silent, I forget since I didn't receive any in at least a year and now suddenly with my new phone) with my og pixel, both are unlocked and not-rooted with stock android. Only other difference is I also needed a new sim card because for some reason it wasn't working in my new phone. I had that sim for over 10 years, used it in my old pixel and was still registered with bell as belonging to a blackberry.
