I’m connected to a Wifi network and my download still isn’t working

To update all of these requirements must be met:

• You need at least 6 GB of free storage
• You must be connected to a Wi-Fi network (and not a personal hotspot) unless it is an iPhone 12 or 13 series with an active 5G network connection
• The phone must be charged to at least 50%, and preferably plugged in so it stays above 50% during the update
• The phone must not be in Low Power Mode
• The phone must not be connected through VPN
• The phone cannot be in Airplane mode

You can’t update using a personal hotspot. It must be Wi-Fi.

If you have a 5G connection you may be able to update using cellular data. Many carriers support that.
