Nokia Lumia 630 (RM-976) Sim Card Reader Connector Repair Replacement Guide For Damaged Broken Pins Solution

The most common cause of this issue on the device is the use of a nano sim card with an adapter.

If you have been using a nano sim inserted into a micro sim adapter, in most cases the sim card will fit into your device and it will read and work fine. However when the sim card is removed, it will catch on the pins of the sim card reader. If force is used to pull the sim card out this will also damage the pins.

If the device shows the following message whilst your sim card is inserted in the device, it means your reader is damaged.

SIM error – The SIM card is missing or invalid. You can still make emergency calls if your mobile operator supports this.

We can fix this problem for you.

Above is a picture of a Nokia Lumia 630 motherboard with a damaged sim card reader, if you look carefully enough you can see that some of the pins are damaged and missing from the motherboard.

The SIM card reader will need replacing by micro-soldering a new sim card reader connector on the printed circuit board (motherboard). Firstly the motherboard will need to be removed from the device. The device will need to be disassembled so that we can access the motherboard.
