Sync iCloud Documents & Data Over a 3G Cellular Connection

iCloud and iOS includes the ability to sync some iCloud data directly over a 3G cellular connection when a wireless network isn’t available. For now, this is limited to “Documents & Data” from the iWork suite of apps, which includes Pages, Numbers, and Keynote. This is a great feature, but due to the bandwidth usage, it should be used sparingly by those who don’t have large data plans with their carrier.
- Launch Settings and tap on “iCloud”
- Tap on “Documents & Data” and slide “Use Cellular” to ON
Be sure to closely monitor data usage with this and other cellular features as to avoid costly overage charges, unless you have an unlimited data plan, of course.

After you sync through 3G it appears on iCloud.com too
