Phone Authentication Provider Problem

Do We need to take DLT certificate for Phone Authentication Provider ? , Which Otp Privider is cheap and best with appwrite mobile authentication.

I dont have an idea but you can see the discussion about it here https://discord.com/channels/564160730845151244/564160731327758347/994283920680034354 and for second part, maybe use Twilio or sendgrid? but you can research on the internet

but twilio takes almost 6 ruppes per otp , that is too much , but like msg91 gives 4 otp in 1 rupees but that tells us for dlt permission

You can use whatever suits the best for your own needs and if it’s supported

can you suggest which one will be best and cheap for indian app?

@Shubham we don't have a comparison list on which vendor is better or worse, because that would depend a lot on your use-case and preferences.

I would recommend spending some time researching the options and making your choice accordingly.

can i change message provider in future in same project.

Sure
