Can I Update My iPhone Using Cellular Data?

Unluckily, Apple doesn't allow users to update their iPhones to iOS 12 via cellular data. The official iOS 12 is about 2.5 GB in size while Apple's cellular download cap is only 150MB, which means you can't install iOS 12 update on cellular data without Wi-Fi.

Though, with the development of communication technology, cellular data is not as expensive as few years before and many of you may enjoy some unlimited data mobile plan; however, actually, it's not. Until now, there isn't any unlimited data mobile plan because of limited technology. The so-called "unlimited data" means that you do have unlimited data, but extra data will be slowed after you have used a certain amount of data.
However, all roads lead to Rome. If you make up your mind to update iPhone to iOS 12 without Wi-Fi, there are always some ways to make it work. Just make sure that you won't be charged for extra data or suffer from slowed data. There are two ways to update iPhone to iOS 12 without Wi-Fi.
