This solution shows the connection lines paths of Nokia 130 sim card circuit on the PCB board layout. By using this solution you can easily determine which components or parts needs to check and or replace.
You may start by checking the SIM card pin connector for possible damaged or lifted. Check if it needs a re-soldering or just cleaning. The colored line paths represents each of the corresponding SIM card connector pins, just do trace each of them carefully then mend to reconnect if somehow there is open or cut connections. Check each of connected capacitors , replace if already damaged.
First thing you need to do is make sure that just dust or rust is not causing this issue clean the Nokia 130 SIM card connector and check if all the legs are in good shape, if there is any kind of damage to the SIM Card connector replace it with a new one.
Check connection between all Pin of SIM socket contacts and Capacitor (at the board near SIM Control). If there is no continuity between capacitor and pin then it shows “Insert SIM” error message.
The picture above is how to fix the Nokia 130 insert sim card. if your Sony is broken at the connector sim then you may try a jumper tricks like the picture above. The first step you need to check the lines as shown. The second step you are trying to replace a component six-legged. I hope this trick can help you. do not hesitate to try.
