We are working on a small app where Indians prefer to login via mobile number and OTP. Firebase/Supabase/Appwrite only support a few OTP providers like twilio and all who seems to be expensive for the India Market. But, there are few local players which are really cheap like 0.2Rs/SMS . What will be your strategy on integrating these cheap providers into Supabase/firebase.

Checkout gupshup
If it's for phone auth, Appwrite Cloud doesn't charge anything extra to use it.
Beyond that, if your audience is only Indians and you're implementing messaging, check MSG91
send OTP over whatsapp or email.
I created a firebase app that uses phone authentication. It works fine for the dummy registered phone number. For other numbers, the service is unreliable with a 10% otp send success rate.
Has anyone faced this before, and solved it?

How does one send messages programmatically without DLT registration in India. Currently using Twilio for this but 13 bucks per SMS is too high.
Wanted help with writing a OTP sending mechanism and I don't mean code, I mean how to register on gupshup , how to get DLT approval etc.
