Or just kill SMS entirely. SMS is old tech from the 1990s. We have better things now, like e-mail over LTE/5G, that work across countries, across devices (whoa!), across providers, across SIM cards (wow!) allow more than 140 characters (wow wow!), and allows easy-to-remember alphanumeric identifiers for user ids (wow wow wow is this the future!). I hate SMS confirmations, I don't want to use my phone number as a username, and I will most certainly never donate to an organization that is using my donations to pay for stupid SMS texts after e-mail was invented.
