I am trying to add my phone number to my apple account so that I can use it to sign in. However once I input the number at 'Sign-In & Security' on my new iPhone, it says unavailable for sign in as it is already in use with another account. And thus I can't access iMessage and facetime. However this was not a problem on my previous iPhone XS. HELP!
iPhone 13
Some people say you can only use a number once for accounts. I don't see Apple saying that anywhere, plus it would mean that you would have to have your own phone number to have an account and I doubt that even in this day and age that nobody is sharing numbers anymore.
So call Apple and ask them what to do.
