How to upgrade on your iPhone, iPad, or iPod touch
Whether you’re on an iPhone, iPad, iPod touch, Mac, or PC, upgrading your iCloud storage is simple. If you need more iCloud storage, you can buy more for a total of up to 4TB. With Apple One, you can choose a subscription plan that includes 50GB, 200GB, or 2TB of iCloud storage. Each month you’ll get an email to remind you of your upcoming payment. You’re billed every month for your storage plan unless you downgrade or cancel your plan. If you upgrade from one paid plan to another, we’ll cancel your existing plan and charge you the prorated cost of your new, larger plan. Your storage is upgraded immediately, and your monthly payment date reflects the purchase date for your plan. You can even share the 200GB and 2TB plans with your family. You can choose from a total of 50GB, 200GB, or 2TB. You can use that space for your iCloud backups, to keep your photos and videos stored in iCloud Photos, and your documents up to date in iCloud Drive. You can buy more storage any time. When you set up iCloud, you automatically get 5GB of storage. If you’re running low on space in your iCloud account, it’s easy to upgrade if you’re willing to spend the money.
