Hard Reset the iPhone
That’s right: switch it off and on again. Hold down the power button until your iPhone powers down. Then do the same to boot it up. Check your messages– hopefully the contact names are back.
Switch off Dial Assist
Okay this one is weird, and we can’t imagine why it would work. But various people have posted it as a success, so let’s give it a whirl. Go to Settings, then Phone. Scroll down to “Dial assist” and slide the slider to “Off”. Then reboot as above- are your message names back? Do let us know!
Dial assist helps with making sure you use the correct dialing prefix when calling to- and from foreign countries, so you may want to re-enable it when you travel abroad.

Go to Settings, General then scroll to the bottom and select Reset. Then choose “Reset Network Settings”. You’ll be asked to put in your security pin, if you use one. Once this has done check your messages and see if everything is okay. Don’t worry if not, we have one more thing to try.
