If you’re like most people, you probably use iCloud to store your photos, music, and other files. But if you want to buy more iCloud storage space on your iPhone, there are a few things you need to know. First, iCloud charges by the gigabyte (GB). So if you want 1GB of storage space for $10 per GB, then it would cost $100 to buy 1GB of iCloud storage. Second, there is a limit to how much data an iPhone can hold in its iCloud account. If your iPhone has 10GB of free storage and you want to add another 5GB of data to your account, then it would cost $25 per GB. Finally, be sure that the amount of iCloud storage that you’re asking for is actually available on your device. If it’s not, then be sure to ask Apple about adding more storage space or upgrading your device.
