Account recovery issues with new iPhone and forgotten password

Last week my phone crashed, I had to get a temporary android until mine came, I knew all my passwords, security questions but I couldn't get the verification text, and finally got my number ported in. Now I got my new iPhone and it says my password is wrong, my phone number is not supported and I answered ALL verifications and still put me in account recovery. Now what good is it actually if you know all the security questions, still can't get in your account. Or what is the point of having to change your password so much you don't remember it, then it tells you that you can't use the previous password (it just said it was wrong) if you still have to go through all this??

If somebody wants to hack my email to get my Dollar General coupons, more power to them, but I need to get in the too!!

No matter what you remember you will always have to do account recovery if you get a new device!!!

Add your phone number to your sign in and security section of your Apple Account. Account.apple.com. You can also set up a recovery contact there.
