Does an iPhone 6s Plus allow the user to change APN settings? If not, how can I change it?

On my iPhone 6s Plus, it does not show APN settings when I go to the cellular data settings. On the iPhone 6+ it showed APN settings under Cellular data options but this iPhone does not show that. If there isn't an option would I have to jail break it?

In iOS 9 and above, you can't change the APN manually. If you''re not getting the right 4G connection, Network Reset the phone and your new APN will be automatically set as per your carrier.
