Welcome to Android Central! Who's your carrier? Are you certain the phone supports your carrier's 4G bands? More and more carriers are requiring that the phones on their network use 4G for phone calls (i.e., VoLTE), since a lot of them have shut down their 2G networks, and will soon shut down their 3G networks as 5G matures.

When you make a call it says not registered then you would have to call your service provider
