Caller ID showing Unknown

[SteveLSmith]

For second time, my Motorola phone with Sky SIM only contract is not showing callers. I had new SIM before but now can't get Sky 150 automated service to understand my problem. No online help for topic. Need help

Are you using Wi-Fi calling?

[SteveLSmith]

I've tried all different settings, including WiFi Calling on and off. No change

Thanks for follow up but still no solution. I don't think I am the only user to have this problem?Seems that Motorola and Sky have compatibility issues so will have to consider leaving Sky.
