why when i update my iphone it says it is paused?

Hey there,

Make sure your iPhone is connected to a power source and good Wi-Fi network and restart your iPhone and see if the update continues. Using a VPN or proxy connections might prevent your device from contacting the iOS update servers.

If you continue to have issues downloading or installing the update, try using a computer with iTunes to complete the process. You can find more info on how to do this here ☞ Update your iPhone, iPad, or iPod touch
