I would get rid of my US number completely, however, i have so many different accounts with 2FA. I hear google phone works, but if youre not in the US at least once a year they can deactivate your account.
My plan is to keep my number for 2FA purposes, and get a local sim for everything else. Right now we are paying for international package and its killing us.
I have a Google Voice number and haven’t lived in the US for almost six years. They’ll send you an email 30 days before deactivation, and all you have to do is log in and make a call or send a text to keep it active.
