I have a question about phone auth. What is required to add a new phone auth platform such as unifonic (https://www.unifonic.com/). we are trying to use phone authentication in MENA region and most SMS's by twilio are blocked by carriers in the region.

You should post your request here in the Supabase Github Discussions page or as an issue in the Supabase auth repo.

On the topic of requirements though, I don’t think there are any set ones, just look at the other providers and PR it, if Supabase want it they will merge the PR

thanks. Do you know of a similar PR I can refer to for implementation?

I can try find one, but I havent personally added any

that's very helpful. thanks!
