Looks like you can't make changes to this plan.

I closed an account last year and plan to start a new plan soon. Since the account is closed the website doesn't allow me to do any update and always shows "Looks like you can't make changes to this plan." when I attempt so.

I also try creating a new ID, but my phone number is locked into my old account and continue preventing me from doing any updates. Is there way to completely remove my account record so that my phone can be used on a new account?
