Default Gold contact near the sim card was broken or missing

Hope I'm in the right threat.

I have T-mobile HTC One S. My screen was broken so i replace it. After finished, when I make in/outgoing call, the person cannot hear me but i can hear them. They can only hear me if my speaker was on. So, i remove the case and look inside and I notice the gold contact near the sim card was broken or missing. Please see picture highlight in red. Is it possible to add something in to replace that gold contact? If so, what do i need to use? I think that's the cause of why they cannot hear me when my speaker was off. Thanks

This is a sample picture.
