How do I activate FaceTime on my iPad?

Here is a link with the step-by-step

1. Go to setting
2. tap "FaceTime"
3. Enter your phone number, Apple ID, or or email address to use with FaceTime

I hope this helps. Please add additional context if you still are unable to set FaceTime up successfully.

It keeps popping up “an error occurred during activation. Try again” what should I do? I know my Apple ID and password are correct.
