Hi @ron16,

Welcome to our community forums and thank you for your first post.

 Sorry to hear you are having issues with contact names on multiple devices. We can understand this is not ideal. 

Please try the following steps and let me know if the issue persists?

Go to: Settings > mobile data > SIM Applications (near bottom) > tap "Roaming" > tap "Select Mode"

Tap manual > then choose National.

Thanks,

No problem at all @ron16.

I had issues with contact names not coming up when receiving calls from people in my contacts list and I had to turn off DIAL ASSIST to dial a number from my contact list.
The reason this was happening was because I had not loaded the numbers correctly. all mobile numbers must be preceded by + 44 and all house numbers in UK preceded with 00 44. This has solved all issues with dialing and receiving calls from my contacts list and I can now use phone with DIAL ASSIST turned on.
