Swapping my phone number every year in the US would be an annoying as hell. Tons of services use phone number as 2FA or a backup recovery. (Including a lot of banks) I use SMS with some people and that would cut contact with them. Same direction if they changed numbers.

using a phone number as 2FA is generally bad practice but yeah I see what you mean. For anything else I think using whatsapp makes more sense
