Apple iPhone data transfer and setup troubleshooting

Users migrating to new iPhone models, such as the iPhone 17 Pro Max or iPhone 18 Pro, can utilize Apple Quick Start for wireless data transfers. To ensure a successful migration, it is recommended to keep both devices connected to power, ensure Wi-Fi and Bluetooth are enabled, and place the phones side by side.

If wireless transfers stall or fail, users can opt for a wired connection using a USB-C cable or restore data from an iCloud or computer backup. For cellular service, eSIM Quick Transfer can be used to move phone numbers, provided the carrier supports the feature. It is advised not to erase or trade in the old device until all data, authentication apps, and mobile services are fully functional on the new iPhone.
