Hi Team,

I have doubt for Azure B2C SMS Cost.

If Example i have 1000 Users(All users are active) in B2C Local Account and configured SMS Based Authentication.

If the users are login attempts 2 or 3 times per day. so, the sms attempts for 3000 time for this tenant per day. approximately 90,000 SMS Requests per month.

i need some support from this point.

I Have 2 B2C tenant.

Tenant 1 User's image

Tenant 2

User's image

Here shows the Billable Units Per Authentication for tenant 1 and Monthly Active Users for Tenant 2.

Please suggest me what is the approximate billing for month for this scenario for this 2 Tenats.

Thanks !.

    Hi @umasankar govindaraj , this is because of the following: "If you linked your Azure AD B2C tenant to a subscription before November 1, 2019, the previous per-authentication billing model is being used. We recommend you upgrade to the monthly active users (MAU) billing model. Billing options are configured in your Azure AD B2C resource." You can find more details here.

    Please let me know if you have any questions and I can help you further.
