How to update with out using WiFi

Unfortunately, it is not possible to update the software without the use of either WiFi or a computer connected to the Internet.

If you have apps installed on your iPad that have been downloaded with an Apple ID that is no longer associated with your device, then you will need to download them again with your new Apple ID.

If you have a PC or Mac, then you can connect your iPad and update through it. However, your computer must also be connected to the Internet.

To reach the internet the PC needs Wi-Fi or ethernet cable from the router.

Park outside of MacDonalds and "borrow" their free Wi-Fi.
