Device don't recognize specific SIM carrier

Hey, must say the device got a little water back few months before it started to make this problem.
The motherboard and every thing looks clean inside.
The problem is when we put a sim card its not recognize there is a sim inside, we tried a new sim and other sim that works 100% on other device, but nothing.
The funny thing is when we put other carrier sim card it recognize it and works fine.
We tried to replace the sim card slot , problem still remains..

The last thing I think about is to replace the charging (usb) port (all this board), do you think it will fix the problem? or what else could be this weird problem?

thanks.

Anyone have any idea about this issue?

BTW, the charging port/board is related to the buttom back-setting touch keys?

Jump my questions again, before I buy this part [charging port board] for nothing...
