Yes of course
No You have to setup Firebase Properly that, Your firebase account should be private and the Mobile Devices will understand the message source is a secure place.
There’s a Big Question of Cloud Communication…
You are using Firebase & Then Using the Kodular Firebase Component. It means your connection is not valid secure. You are getting an Result from Firebase then it get into Kodular Server After that, It will deliver to the Mobile device. And the Mobile Messages AI guessed the message as a spam because it travelled two times. There may be some tweaks.
What does private here mean?
That means that all applications created with Kodular will have the same problem that I am facing
Check other Topic, If You found any other solution. As Far I know this types of problems are not so common. I have to test this personally now, Then I will say you whats the problem.
Then Try Using way2sms extension or Using Web API.
I am testing these things. I will post the aia here if it works.

Ok i will try this , But what about firebase??
Try this one, There may be some errors in the authentication. I will make you inform.
Hi @Ariyan_AD I hope you are fine
This is only for Indian user as I think 
As for the problem of OTP messages that I am facing in my application, I have done two things so that I can determine the cause of this problem
First, I found that the problem is in all of my applications, not in one application. All my apps don’t send OTP to users
Secondly, I activated a new Firebase account using a different Gmail and the problem still exists in the application and it still does not send an OTP message to the user
We conclude from this that either there is a problem with my blocks , or there is a problem with the Authentication component
Label6 is country code
Text _Box1 is Phone Number

Yes @sherif , I am totally fine.
Have you setup your firebase account properly.?
I mean to say, make sure you have done this…
Note: Give me some time to contact with Googlers ok! Then I will be able to understand and solve this problem if there any problem in Firebase.
Please wait. Ok! 
Hey, @sherif
I have contacted with Google team, they made me believe that it’s not a problem of firebase. The problem is with the System, Means the way you are using.
You have to find a different way of sending the messages. Because the way you are using this message feature is incorrect, if you send any message to any number then it arrived only for 1 time but if you try 2nd time then It doesn’t because the data ( means the number ) was saved in FB database so it will not send any message to it again.
