I just had to go through a lot of hoops to switch from a physical sim to a new esim on a new phone. My brother had a sim swap attack occur a couple of weeks ago in an attempt we think to get to the small bit of crypto he had. Apparently a sim swap attack was attempted and thwarted again earlier this year but they did not give me any details to me about the attack. I'm glad our account has this extra protection on it but I'm still going to be going through and removing SMS 2FA on anything remotely important.
