It's important to understand that each method has its own technical requirements, and ignoring them may result in boot failure. Therefore, carefully review the hardware and software requirements before beginning any steps.
Modern versions of the operating system take up a significant amount of memory, often exceeding several gigabytes. Loading such a volume of data through mobile Internet It can be not only slow but also expensive if you don't have an unlimited data plan. That's why using a wired connection to a computer remains the most reliable and expert-recommended method.

Finally, check the condition of the cable. Use the original or certified one. Lightning/USB-C cable Guarantees stable connection and high-speed data transfer. Cheaper alternatives are often only suitable for charging and can cause connection interruptions at the most inopportune moments, leading to update errors.
☑️ Ready for upgrade
Using mobile internet for downloading
Starting with certain versions iOSApple allowed users to download updates directly over the cellular network, as long as the package size doesn't exceed the carrier's limits. However, this feature is often limited by default to avoid unintentional data usage. To enable downloads over the cellular network, mobile data, you may need to change the settings in the cellular menu.
Go to Settings → Cellular and scroll to the bottom of the page. There you'll find "Cellular Data Options." In some regions and software versions, there may be a toggle allowing downloads larger than 200 MB.

Updating via Finder on macOS
For computer owners Mac The process is even more integrated into the system. In macOS Catalina and later, the iTunes function is deprecated, and device management is carried out through FinderThis makes the process as simple and convenient as possible. Connect your iPhone to your Mac via cable and open a Finder window.
