Apple provides the first 5GB of iCloud storage for free. That may be enough if you are using your Apple ID on only one device. If you have more devices linked or if you just have a lot of data, you will need to consider increasing your amount of iCloud storage.
If you have your iPod, iPad, and iPhone all linked to one account, you will soon notice that you do not have enough space to back up all of your devices to the cloud. Likewise, people with a lot of media or documents are unlikely to have enough iCloud space.
The following items actually consume iCloud storage:
1. Photos and videos in the Camera Roll
2. Device settings
3. App data
4. Home screen and app organization
7. Visual Voicemails
You can check the current amount of available iCloud space through this tutorial.
If you use up all your space, Apple provides an affordable solution to this storage problem. By following the instructions below, you can upgrade your iCloud storage plan.

2.Scroll down until you see iCloud and select it.
