That's alright, because the first time I get one of those, my 4G SIM goes into the 4G router I can carry in my pocket and my phone goes into wifi only / no-SIM mode.
Still get data, still get texts, can still make calls (VoIP, etc.) but won't be bothered by other people's "tests", alerts or anything else because the router literally doesn't have a method to alert me (no speaker).
If you keep it for absolute and targeted emergencies, we're good. If we start getting that "wake the entire nation at 3am because of a vulnerable adult who's gone on a bus ride on their own" nonsense like America get, you can alert the inside of a silicon chip as far as I'm concerned.
