Problems with sim card

[Luke Benge]

So I replaced the screen on a galaxy s4.
The screen worked and shortly after the phone started to tell me the sim was not connected and it had to restart. It would ten work for a while but ehn do the same thing.
I then replaced the sim card tray.
It is doing the exact same thing....what is going on?! Does anyone have any ideas on how to fix this??

It might be that a wire is loose/not connected. Did you yourself replace the screen or did another third party group do it?
