Hey there @MikeR,
Welcome to the Community.
If you're still experiencing an issue, try the following:
Turn your phone off/on. It sounds so simple, but sometimes a fresh connection to the network is all that you need.
Make sure your phone is on the most up-to-date OS.
Check your phone settings for some basics:
- Make sure airplane mode is off
- Make sure call blocking features like Do Not Disturb are off
- Check that Call Forwarding is off
- Check that your network mode is set to automatic
- Disconnect any accessories
- Check that you have network coverage
- Try moving outside if you’re inside for better network connection
