The phone says “No network connection”. And it has a little circle with a line through it where it would usually show signal strength. It wont make any calls either. I just put a brand new screen,frame,back glass and battery in it. Not sure if it makes a difference though. Any help would be appreciated as I am planning on selling my s9 soon to get the s10. Thanks! (I have already tried the SIM in another phone. It works fine.)
Hi Ethan, Make sure that all your antenna cables are properly plugged in and intact. Samsung Galaxy S8 Motherboard Replacement
Iam not an expert, but do check if IMEI number is there in settings. If not it will not recognize any sim card.
