Use iCloud on iPhone
iCloud securely stores your photos, videos, documents, backups, and more—and keeps them updated across all your devices—automatically. With iCloud, you can also share photos, calendars, notes, folders, and files with friends and family. iCloud provides you with an email account and 5 GB of free storage for your data. For more storage and additional features, you can subscribe to iCloud+.
Note: Some iCloud features have minimum system requirements. The availability of iCloud and its features varies by country or region.
