My new number but apple id already in use by another account

I bought a new SIM and when I try to add to my apple account it say-: the number already in use by another account. How is it possible? Called support they suggested two factor authentication ,tried it, it only gets added as trusted number for two factor aunthrntication but still I cannot add my New number to my account. Very annoying, HOW CAN APPLE HAVE SUCH A FLAW IN SECURITY?Why cannnot apple send vetification code to the number and allow change? IS APPLE NOT AWARE ON HOW NUMBER PORTABILITY WORK?

Sounds like you were give a number that previously belonged to someone who registered it to their Apple ID and never de-registered it...

Try de-registering it here: Deregister and Turn Off iMessage - Apple Support

Then re register it to your account.

The phone number you use must have SMS enabled from your cellular provider. That is how it will be recognized by Apple and be added to your Apple ID as a trusted device.

...With two step authentication of password and security question all is fine, Also two factor authentication work with the my new SIM...

You can only have one or the other security method for your Apple ID and would be listed at Manage your Apple ID. These authentication methods have nothing to do with your SIM card. Which one exactly do you have:

Two-step verification
Two-factor authentication

Can you successfully log into Manage your Apple ID with your Apple ID that is being used with your iPhone?
Is your iPhone listed as one of your trusted devices?
Is your Apple ID secured with two-step verification OR two-factor authentication?
Did you buy your iPhone directly from Apple new?

WHAT says number unknown? You have not yet adequately described what your problem is. Where are you seeing "number unknown?"

Does this have something to do with iMessage? Who is your carrier and what country are you in? If you are using an unsupported carrier, iMessage may not be able to activate with your phone number.
