At the bottom of the phone you have the headset, charging and easy flash (USB) connectors. If the easy flash (USB) connector is soiled, oxidized, dirty or the terminals are shorted; it can cause the sim card issue. The unit starts and takes long to display then "insert sim card" appears. To resolve the issue:
Clean the easy flash connector with a lacquer thinner or even a 70% ethyl alcohol.
Make sure dirt is removed between the terminals.
If you can disassemble the unit, clean the connectors terminals from inside.
Clean also the board.
To disassemble the unit:
Remove A and B-covers.
Remove the six T6 screws.
Pry the board including the LCD frame and light guide assembly from the sides to remove it from the D-cover.
