Ответ на "Galaxy S8 - No cellular signal"Perhaps these two cents may help you all. I too had this issue with my Samsung Note 8. I made sure my connections were solid and it still didn’t work. Gratefully, my old charging port worked outside of the actual usb port itself. I compared the new one versus the old one and my old one would connect to the network and the new one wouldn’t. That’s when I checked the model numbers. My device is the N950U model (for the US) and the new charging port I was trying to put in was the N950F model (for Europe and Australia). Oops! Verify that first and see if that may be the conflict. Hope this helps! UPDATE: Received the replacement N950U charging port and the data reception is flawless.
