Hi all, I have a problem that I need to fix in 24 hours. I’ve just done a screen repair on a customers Samsung S7, something that I have done many times before however this time after putting it back together, it isn’t reading the sim. This of course is a major problem. Any suggestions would be greatly appreciated.

take the sim out and clean the gold part, if that does not resolve the issue then, try to factory reset the phone hopefully that might fix the issue.
