Updating via a computer using iTunes and Finder

The most reliable and proven way to install a new OS version without Wi-Fi is to use a personal computer. This method doesn't rely on the phone's mobile internet speed, as the computer can use a wired connection or its own data channel. You'll need a cable for this. Lightning or USB-C and the installed program iTunes (for Windows and macOS up to 10.15) or Finder (for macOS 10.15 and later).

The process begins by connecting the device to the computer. Once the device is detected by the system, open the corresponding application. You'll see your device's icon in the program interface.
