iOS 15: How To Enable iCloud Backup Over Mobile Data on your iPhone

If you own an Apple device, iCloud is a great tool to upload full device backups, backup files, documents, photos, or any other form of data onto the cloud. This makes sure you have access to all of your important data from anywhere, even if you lose access to the device you backed up from. 

For years, Apple only allowed you to back up your data on an iPhone over a WiFi network. Can you now back up data using your cellular data and if so, how? That’s what we’re going to talk about in this post. 

Can you back up content to iCloud over Mobile Data?

Yes, you can now take advantage of cellular data on your iPhone to backup contents from your phone onto your iCloud storage. This will not only give you two ways to get your stuff backed up but if you think the cellular network is faster than your WiFi connection, you may be able to back up your device in minimum time.

Note: It’s important to note that you do not use this feature on a metered connection since there’s a chance your data consumption may go over your preset limit, at which point, you may end up paying an added cost for the additional data that your iPhone consumed.

What do you need to use iCloud Backup over Mobile Data?

You can back up your iPhone onto iCloud over Mobile Data only if you meet the following requirements:

  • You own a 5G-enabled iPhone – iPhone 12, iPhone 12 mini, iPhone 12 Pro, or iPhone 12 Pro Max. Apple has confirmed on its official site that iCloud Backup through cellular data will only be “enhanced by faster 5G connectivity”. If you own an older iPhone model, you won’t be able to use the feature. 

  • Your iPhone is running iOS 15 – The ability to enable iCloud Backup over Mobile Data is a feature that comes via the iOS 15 update. You can head over to Settings > General > Software Update to update your device to iOS 15. Once updated, you can follow the guide below to enable backup over mobile data. 
  • (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. Using a metered connection for backing up may lead to additional costs you’d have to incur if your data usage goes beyond your network limit.

  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?
