How to update iOS without Wi-Fi: all the methods with detailed instructions

Update iOS without a Wi-Fi connection it seems impossible: Apple Blocks downloading large firmware files over mobile data to avoid unexpected data charges. However, there are legal workarounds—from using iTunes (Finder) before creating a local network from a laptop. In this article we will analyze all current methods for 2026, including hidden settings iPhone and alternative Internet sources.
