Can you back up to iCloud without Wifi?

Re: “… Thanks, but I thought iTunes was discontinued? And I don't have a Mac, I have a PC …”

You are correct that that “iTunes” was discontinued within the “Apple Ecosystem”

What happened to iTunes? - Apple Support

But the Windows PC software which you can use to backup your device TO a PC is still called “iTunes for Windows”

Download and use iTunes for Windows 10 - Apple Support

See ⤵️

Make sure your Windows PC is up to date.

Update to the latest version of iTunes

You can utilize your mobile data to back up your data on iCloud. I'm uncertain as to why you prefer to use a hotspot instead.

Of course. Use iTunes (PC) or finder on your Mac to create a backup

iTunes has not been discontinued. The current version is here:
