Re: A nuisance, an imposition but not the end of the world
You could leave your normal sim at home and use a payg for travel in the US. That way, they don't get the 2fa codes.
Or, use the payg sim for the codes instead, just leave it at home. If you need a code, leave the phone with a friend and say only forward them to my number if I request it personally from you via a phone call.
