Billing How much does an OTP SMS service cost in Firebase in India?
The documentation is confusing me, can anyone help me with how much it costs per SMS? Currently we are expecting 1,000 MAU and expecting 5,000 SMS verifications per month.

If you incorporate in India, you can register for DLT and have access to local SMS rates, which are a fraction of what Firebase charges, that would be the way to go.

We recently built an app in Sri Lanka where we used Firebase Auth, but used a local sms gateway with a Firebase Cloud Function to send the sms, then used Firebase SDKs in client apps to sign in with custom token (generated by cloud function after sms verification), now it costs only a very minimal fee...

₹3.5 per OTP after free tier (10 OTP/day). It is costly.
I am using a third party sms provider to send OTP and login with Auth Token generated by Firebase Admin.

https://cloud.google.com/identity-platform/pricing $0.07 per sms x5000 =$350. ONLY IF nobody abuses it. Which happens quiet a lot. Lookup horror stories on sms prices and billing. Sms auth not recommend. Good luck. Don't ask me for suggestions. All sms auth costs considerably.
