I think you have to change the uem but that's very difficult job because it's under-filled.

Try to switch to other system.
Meaning that if you in GSM(900MHz), try testing DCS(1800MHz) or PCS (1900MHz). And then test it.
If you don’t have Agilent test equipment try to search network providers (manual search).

Then…..
If you realize that one of PCS/DCS/GSM doesn't work (while others do) that means that the problem is defiantly in your antenna SW (or disconnection in that area of PCB) that commands the network switching.

If you find out that you can find all the providers (manual search), but still have a problem in the network (full reception after manual search but still can't make a call) then your RF circuit is fine, but the problem is the power supply, so try to reheat the D400 and look if that helps (nokia always have a problem with Upp).

Good luck.
