The interesting thing about SMS is this isn't always usable while traveling. For example my phone provider has really overpriced international fees ($10 / day) so instead I use an eSIM which usually only comes with data. That means I lose the ability to use text messages or phone calls for any form of verification. A number of banks and other sites also block Google Voice / VoIP numbers.
