What you get

Inside Firebase Authentication phone SMS (first 10 a day free)

Google's Identity Platform pricing says the first ten SMS sent per day for phone and multi-factor authentication are not billed, and SMS after that is billed per message sent, by region. Firebase's authentication limits page says verification code SMS messages are on the pay-as-you-go Blaze plan only, and that limits on verification SMS depend on whether Identity Platform is enabled.
