Q: icloud verification error when signing in

Hello keamogetsefrompretoria!

Looks like there's some issue with your iPhone 5c signing into iCloud.  We can check a few things.

If you haven't, try restarting the iPhone first and try after that: Restart your iPhone, iPad, or iPod touch - Apple Support

Then confirm that your Apple ID is able to sign in here: Manage your Apple ID

After that, if you're still getting error messages, try a different network with the iPhone.  For instance, switch to cellular (LTE/3G) if you're on Wi-Fi or try a different Wi-Fi network.

Hope those help! Regards.
