Here's some tips on how to fix Nokia 6710 with Insert Sim card problem.
If the phone doesn't detect the SIM card inserted to it, there is a possibility that there is something wrong on the hardware components on the device.
This solution below might possibly help fix when such problem occurred, especially when the phone suffered wet damaged or accidentally dropped. If these things happens, you may first check the SIM card pin connector for possible damaged, ensure that all the pins were cleaned.
In Nokia 6710 circuit assembly, the SIM card pin connector is being isolated on one PCB board and used an expander pin connector. You may first check the SIM card pin connector PCB board assembly then cleaned the expander terminal contact pads to ensure a good connection.
If the SIM pin connector board and the expander terminals were both okay, you may then proceed to trace the VSIM (sim supply voltage) line paths. There are chip capacitors that are connected to each of the SIM card data signals as shown on the solution above, these capacitors has a 10 picafarad values. Check and replace these components as well.
As observed, that all the corresponding connection line paths of the SIM card is feeds to the power IC. You may need to rework the power chip for further or deeper troubleshooting. Thanks to mobile phone repair guides for sharing this solution.
