Backing Up Over Mobile Data

[Vlad Soare]

Hi,

Is this a joke? What's that toggle supposed to do, if I must be connected to wi-fi anyway?

Thanks.

Guessing need to be on 5G to do backup vs 3G in the screenshot:

Back up iPhone

Back up iPhone using iCloud or your computer. If you replace your iPhone, you can use the backup to transfer your information to the new device.

Note: On models that support 5G, your carrier may give you the option to back up iPhone using your cellular network. Go to Settings > [your name] > iCloud > iCloud Backup, then turn on or off Backup Over Cellular.

Yup. Requires 5G and is carrier dependant.

Yes, it seems the 3G was the issue. It doesn't actually require 5G, it works on 4G as well (I'm on 4G now and it's enabled), but apparently it considers 3G unworthy.
Thanks.
