Why can’t I turn on my iCloud backup

Hi shon243,

Thanks for connecting with us here in Apple Support Communities. What happens when you try turning on iCloud Backup? Do you get an error message when doing so? Make sure you're following the steps shown here: How to back up your iPhone or iPad with iCloud

1. Connect your device to a Wi-Fi network.

2. Go to Settings > [your name], and tap iCloud.

3. Tap iCloud Backup.

4. Tap Back Up Now. Stay connected to your Wi-Fi network until the process ends. Under Back Up Now, you'll see the date and time of your last backup. If you get an alert that you don't have enough iCloud storage space to complete the backup, follow the onscreen steps to upgrade your iCloud storage.

Keep us posted.

Thanks.
