Which SMS Gateway you are using?

I have attempted to implement that but i am stuck on in what sequence i should use blocks to get it work.

Here is what i have tried

  1. When User clicks on Sign Up, i am using Firebase Authentication.phone number sign in by passing the user phone number (Question: Here should we pass the phone number including country code or just 10 digit mobile number)
  2. Next Once the user types the code on the screen i am using Firebase Authentication.Verify Phone code by passing the code entered by the user
  3. Then based on all this i am using login success and login failed blocks

But I haven’t got any sms delivered to the number i have provided. Am i missing something here?

Note: I have already enabled the phone sign on on firebase developer console and got the json from there which i have imported to assets.
