Hi Linou1925,

To use Quick Start to transfer data to your device, we recommend that you follow the steps in the link below: Use Quick Start to transfer data to a new iPhone or iPad - Apple Support

Next, we’d like to show you how to perform the recommended troubleshooting steps via the link above. Please click to open the link, then read through and follow the steps in the section below.

1) Make sure that your current device is connected to Wi-Fi and Bluetooth is on. Turn on your new device and place it near your current device. Follow the onscreen instructions to get started. If the prompt to set up your new device disappears from your current device, restart both devices.

2) Connect your device to Wi-Fi or your device's cellular network.

3) You might be asked to activate your cellular service.

4) Set up Face ID or Touch ID.

5) Choose how you want to transfer your data.

*If you download from iCloud, your apps and data download in the background so that you can start using your new device right away.

*If you transfer directly from your previous device, you'll need to wait for the transfer to complete on both devices before you can use them.

6) Keep your devices near each other and plugged in to power until the data migration process is complete. Transfer times can vary based on factors such as network conditions and the amount of data being transferred.

The reason why we are recommending the steps above is because they will show you how to transfer data to your device via Quick Start.

Please do not hesitate to reach back out to us if you have questions or need any additional support.
