It's also one of the least secure 2FA methods since you have to trust all your phone company's call center employees to not transfer your phone number to a new SIM controlled by someone impersonating you. Lots of reasons to not use SMS for 2FA.
- three_seagrass 6y agoPixel phones are now preventing sim swapping, IIRC, and maybe a few others.

I would understand Fi having better protection because you have to manage it online through your Google account (and same for Google Voice users). Not sure what a phone would be able to do about it. Anyway, Google as your phone provider opens up a different can of worms. Instead of having an overly helpful support staff who can be tricked into doing things they shouldn't, now you have Google's algorithmic account bans and tie-in with Google Payments and no recourse for problems because the customer service is a robot that says "no". https://news.ycombinator.com/item?id=18886804 https://news.ycombinator.com/item?id=18886804 Nonexistent support is great in terms of resistance to social engineering, but sometimes you need support.
