Everyone I want to talk to knows not to call me; I feel exactly the same. Phones used to be useful, but the sheer volume of telemarketers and scams have reduced it to uselessness. If it wasn't for 2FA occasionally requiring a phone number, I wouldn't even have one at this point.

You don’t always have a choice as it is dictated by the service provider, but whenever possible, disable SMS based MFA and enable TOTP or something else. SMS based MFA is susceptible to SS7 MitM attack.

2FA

Use an authenticator or Yubi key. SMS authentication is the worst possible method.
