Other than avoiding those services as much as possible, I use a second phone number for “machine-communication”= whenever I’m not giving my phone# to a person.

I’m in the EU, I found a provider in my country that offered a prepaid sim card (pay-per-use) with no expiry date, but never use the credit on it because it’s free to receive sms. I turn it on in my dual sim phone whenever I need it.
