$6 million per year on outgoing SMS? Do not send SMS to users, make users send SMS to you instead to confirm their numbers! I have this solution for years and it works >90% of the time. The rest 10% is calling a verification number which drops calls with busy signal (no fees for the caller) but sees who is calling and is able to verify their number.

It would be great if Signal wouldn't require a phone number for account setup at all

this is in testing and coming to you early next year.

Would invites be a solution? Anyone can sign up if they provide a number, otherwise you need an invite from someone with a number linked. It would clump the identity/legitimacy for all invitees into origin number, but still allow disparate accounts.

>>travis+I61
It’s not about legitimacy but having a bootstrapped contact list to talk to along with other user friction reasons

>>novok+S71
In that case it doesn't make sense to make it required.

Sure, I don't mind if they ask for my phone number if they think that's a better default onboarding flow, but allow users to bypass it.

With all that said, I don't think it's really only about user friction.
