How about if those not show like that so I able to download that?

Hello taholo,

Keep your device updated is important since it installs bug fixes and security updates. From the screenshot we see Low Power Mode is on, a Hotspot connection, and you're not connected to a Wi-Fi network. The alert also shows you'll want to connect to Wi-Fi. Here's more information on Low Power Mode and how to turn it off: Use Low Power Mode to save battery life on your iPhone or iPad - Apple Support

The guide you recently viewed also has great steps on updating and how to update from a computer, if you're not able to update wirelessly. Be sure to back up before updating. Here's that link, just in case: Update your iPhone, iPad, or iPod touch - Apple Support

Thank you for posting in Apple Support Communities.

Regards.
