Check IMEI number under *#06#. If nothing shows up then there's an issue relating to baseband chip.

It´s quite hard to repair the baseband because you can´t replace the chip with a new one because it's bound to the logicboard. You can try to reflow the chip first. If this doesn´t work out, you can try reballing.
But the problem can also be caused by defective solder pads. You better bring it to a specialist for micro soldering. You need a lot of experience to perform such a repair. If you have no experience you gonna mess it up.
