It seems like the places that rely on SMS generally don't have hardware 2FA. Or, most websites that allow configuring multiple 2FA methods support disabling SMS The ones that let you configure a single MFA method or single with backup are usually where I run into issues, personally For instance, on Github, I have 2x U2F tokens and paper recovery codes but there's not even a phone number configured on the account
