Receiving a new iPhone 12 Pro Max
Hello. I currently have an iPhone 6s Plus under ATT. If I order an iPhone 12 Pro Max and it is shipped to me, how do I transfer everything to the new phone ? SIM card, account, files, email, apps, contacts, etc... ? I usually buy iPhones at the Apple store (for me and my family), and they do all the transfers for me. I am afraid if I order a new iPhone to be shipped to be, I won't be able to do all the necessary transfers.
