No service after screen replacement

Got given a P20 Pro to replace the LCD as it was not working, and was completely smashed on the back.

Replaced the screen, all starts fine, WiFi works but says no service.

Antenna is secured to the frame properly.

Coax cables are snapped in firmly and are not mixed up.

Tried resetting network settings

Cleared Cache

Performed factory reset.

Any other ideas?

Thanks

Customer isn't too fussed, as he just wanted the photos off the phone originally.

This happened to me after screen replacement. Take your sim card out and flip it 180 and put it back in (face up to face down if that makes any sense)

Mine worked after that!

It happens after a battery replacement. These phones must detect the replacement battery. The phone just gets a poor signal indoors but works fine outside. I think I'm going to put the old battery back in and see of it makes a difference and I'll report back. I only replaced the battery because I was replacing the back for a customer.
