HTC U23 Pro
256 GB, Coffee black, 6.70", Dual SIM, 5G
I bought this HTC U23 Pro, inserted new sim card from UPC/Sunrise and don't recognise the calls. Everything comes in as Unknown on the home screen. UPC/Sunrise has checked the sim card, everything is fine. It should be a setting in the device. Can anyone help me why I don't see the clip, why everything is unknown? It would be enough if I could at least see the phone number to call back in case of absence....
