Can you download iOS on cellular data?
There’s no known way to date to update iOS over cellular data, as per Apple’s requirements. The only way to update iOS over-the-air is to connect to a WiFi network or to connect via USB and iTunes for non-OTA.
How do I download iOS update over cellular?
Per Apple’s support document on 5G (via MacRumors), you need to go to Settings > Cellular > Cellular Data Options, and tick the option that says “Allow More Data on 5G”. After you’ve done that, you’ll be able to get iOS updates over a cellular network.
