Why is my iPhone blocking iOS updates over mobile data?
Apple limits the download of updates iOS via cellular network for several reasons:
1. Firmware file size. Updates iOS often weigh 2–6 GB — this can quickly exhaust your mobile data limit, especially on plans with a small internet package. For example, updating from iOS 16 to iOS 17 on iPhone 13 takes about 5.5 GB.
