According to a letter seen by MacRumors, Apple says that “there is a known issue for iOS 16 that may impact device activations on open Wi-Fi networks.” Apple advises customers to choose “Connect to Mac or to a PC with iTunes” to connect to a Wi-Fi network during the first iOS onboarding process, then go back to the previous screen and try again on Wi-Fi until the activation completes successfully.
There are currently no official solutions, according to Apple, and support staff members are advised: “not create a repair [case] for the issue.” The glitch is unfortunate because pre-ordered iPhone 14, iPhone 14 Pro, and iPhone 14 Pro Max models are now shipping to customers worldwide (iPhone 14 Plus will ship from Oct. 7, 2022).
An update to iOS 16.0.1 is now available for new owners of the iPhone 14 that fixes a problem with setup activation and migration. If you’re having trouble activating your iPhone 14 right out of the box, you might need to restore it with a Mac or PC to iOS 16, to fix the bug and properly activate your new iPhone.
Apple warns new owners of the iPhone 14 and iPhone 14 Pro in a support article that “iMessage and FaceTime might not complete activation” until their new iPhones have been updated to iOS 16.0.1.
