Help No Radio after Rear Camera replacement

I replaced the rear camera. Everything works fine...... Except the cell radio is inop and won't pick up a tower. SIM Status = Network: No network connection, Mobile Network State: Disconnected, Service State: Radio Off. IMS registration status: Off

I've been back in it to confirm connections several times. The WiFi radio works fine and allows me to connect.

I've had Samsung cells apart at least 10 times for screens and ports. Never saw this issue. I'm just trying to find out if I need another motherboard or if the firm/hardware is failing.

Any advice?
Thanks in advance,
