This provides a solution for Nokia 5630 xpressmusic with insert SIM card problem or if the device does not detect any working SIM card being inserted to it. This problem occurred or sometimes happens if the device suffered wet or water damaged or an oxidation build up through to the SIM card pin connector and it corresponding circuit components. This solution below provides some hints on how to fix this the device.
If this kind of problem happens, you may first clean the SIM card pin connectors surroundings , for possible dirt and oxidation build-up.
Refer to the solution below if the problem still exists and shows "INSERT SIM CARD", and locate some particular indicated and highlighted components on 5630 PCB board, then do some check up procedures.
Locate the components and check the SIM card supply voltage (VSIM) and ground (GND) pins connection line paths trough the components where it is being connected, aside from the ground pins which is only connected to the groundings of the PCB board.
There are components such as resistors and capacitors near the SIM Card pin connector.
Check those certain components and then replace it with the same rated values, if already damaged.
