ios 16 update

Hello Rushiket,

Thanks for using the Apple Support Communities!

Are you attempting to update your iPhone from Settings? Do you have access to a Mac or PC?

If so, try these steps to see if you can update using your computer:

If you're using a Mac with macOS Catalina or later: Update your iPhone, iPad, or iPod touch with the Finder - Apple Support

If you're using a Mac with macOS Mojave and earlier or a Windows PC: Update your iPhone, iPad, or iPod touch with iTunes - Apple Support

Hope that helps!

Rushiket,

It’s our pleasure to help! Should you need help in the future, don’t hesitate to consult your local community by creating a new post. 

Best wishes.
