Backing up your iCloud data will download large quantities of photos/videos from your iCloud account, which uses a lot of internet data. When the "download using Wi-Fi only" option is enabled, the Qubii app will make sure that data is only synced when connected to a stable Wi-Fi connection, ensuring that your data limit will not be accidentally surpassed. Because of this, Qubii will only back up your iCloud photos and social media content when connected to Wi-Fi.
Enable "Download using Wi-Fi only"
In the Qubii/Qubii Pro app, go to Setting > Click "Backup Items" > Turn on the “Download using Wi-Fi only" option
*Please Note: Before initiating an iCloud backup, ensure that you have enough space on your phone to sync the items from your iCloud onto your device. Due to Apple's third-party device restrictions, iCloud data will first need to be downloaded onto your device before it can be backed up to your Qubii.
