No Caller ID/Phone Number

Hello,

I have an iPhone SE, running on iOS 12.0.1. When phone calls are coming in, including from my own contacts, it says “No Caller ID” and no phone number is shown. We have checked, and we all have our caller IDs enabled. I have tried updating my iOS and restarting my phone, but the same issue is occurring. Is there a way to fix this issue?

Thanks!
