By default, Apple backs up your device data over Wi-Fi networks but you can also use the cellular data on your iPhone to backup contents onto your iCloud storage. This will be helpful for users whose cellular data is faster than the Wi-Fi network they’re connected to as it can minimize the duration of backups significantly.

  • (Optional) You have an unmetered cellular data connection – The size of iCloud Backups may vary depending on what you have to copy from your iPhone to the cloud.

  1. I have updated to iOS 15, and my phone is up to date, but the option to use my cellular data for back ups isn’t given to me. Is there a reason?

  2. Could it be that this setzing overrides „Roaming off“?
    I was in Brazil, had zero data transfer the whole day except at 2a.m. when I was fully asleep. Now I received a phone bill of 500+$ …!
    Found no other explanation.

  3. So my iPhone SE (2) has the option to upgrade to iOS 15. Is iOS 15 alone sufficient to backup over cellular?
