1 Which part of the phone has to do with SIM functionality
I'm kind of having the same issue, but calls and data work. S21 plus, when i turn the phone on the screen to register comes up and does it thing, then fails, but as stated, calls still work etc. Is that a sim card reader fault or mother board issue?

And it fails after. But still have 5G and data. Does it every time I turn the phone on.

Safe mode didn’t work. But I did notice when you turn the phone on, whatever chip is under the cover is getting super super hot. I don’t know if that’s a partial short, I don’t have my air station yet to pull the cover off. But that might be the issue. Would you have an idea what chip or chip’s are under that?

Hi @forrestlambert
What do you mean by ..."i turn the phone on the screen to register comes up and does it thing, then fails,.....", what exactly happens when it fails?
If calls still work then the SIM card reader is still doing it's primary function i.e. phone can read SIM card and this allows access to the mobile phone network
