How can I upgrade my phone to ios 10?

I have an Iphone 5c cause I don't have enough money for the other iphones. So how can I upgrade my phone to ios 10?

IOS 10 or 13? 10 is very outdated.

No. Apple no longer supports your phone.

You can upgrade to iOS 10 or 11 or 12 or13 because the 5 is and old version sorry

The same way you do any IOS update on an iPhone. 5c is compatible with IOS 10.

Just upgrade to the new ios 13

10.3.3 is the latest iOS you can upgrade a 5c to.

By upgrading them to 12 or 13
