How to backup iCloud via cellular data

You just need to open Settings on your phone and then we tap on Cellular to adjust. Switching to the new interface, users just need to enable iCloud Backup mode to back up iCloud data via cellular data.

Before enabling this feature, you should note that this will increase your mobile data usage, so you will run out of data quite quickly. If you have a limited data plan with your carrier, avoid using this feature and only back up your device over Wi-Fi.
