Replaced sim reader, but error still there

First with no sim inserted the phone displayed “sim error” with sim card inserted there was the same error, so first i did a system reset, but no difference.

Then i removed the old sim reader, soldered a new one, but the message still appears, no matter what.. Is this some defect?

As a solution i saw in one blog, i will make jumpers from the sim ic to the pads of the reader.
