Upgrading iCloud Drive
A new iCloud account comes with 5GB of free storage available. If you use your iCloud Drive a lot though, you may run out of space, especially if you also back up your iOS device to the cloud.
Thankfully, it’s easy to purchase more storage for your iCloud Drive. This four step solution will help you out, and the price plan is reasonable too.
