When you buy an iPhone, you automatically get 5GB of free storage on Apple's iCloud service. But, if that's not enough space for all your photos, documents, messages, and other data, you may need to consider buying more iCloud storage space.
Apple offers a number of plans, and you can upgrade from your iPhone's Settings app. Here's how to upgrade your iCloud storage plan on your Apple device.
How to buy more iCloud storage on your iPhone, iPad, or iPod Touch
