Hi All, I don't have Wi-Fi newtwork, anyone can help me how to download iOS 8.3 using mobile 3G internet? Thank you.

Hi,

You cannot download an iOS update via a cellular network. You can hook up your device to iTunes on the computer you sync with and update the iOS via iTunes, however.

Best of luck,

Does it say that you must be connected to WiFi? Also, which generation iPhone is this?

You must be connected to Wifi to update the iOS OTA.
