Wrong phone number as primary account holder
I finally purchased 4 iPhones for my family. I got them all the same day and unfortunately I forgot which phone was mine because 3 were the same color. I thought that I could just start the account online and select myself as the primary account holder but I’m seeing that that’s not how this works. Do I have to take the phones back to the store I got them from to correct the account holder information or can I do it through the website? Any help would be so greatly appreciated.
