I left my nano-to-micro sim adapter inside the sim slot of my mobile. While trying to take the adapter out of the sim card slot, I have bent/damaged the sim card slot pins. Now my phone does not read the sim any more. How to repair the damaged sim card slot
I tried to unsolder the sim card socket with a hot air solder station. Way too risky as there is too much little components around. Overheating them may result random behaviors afterwards. Moreover, there is 13+ solrdering points not accessible.
The trick I used is to replace the damaged pins. Here the way to proceed - We are considering here you already took the motherboard out of the OnePlus One.
1/ Needed tools
- Office adhesive tape
- A Dremel with a diamond cutting disk
- Tweezers
- Clock repair magnifier
- Soldering paste
- Hot air soldering station
- A spare sim card socket adapted - got
2/ Procedure
- Apply adhesive tape all around the socket to prevent small metalic particles to go everywhere and cause short circuits
- Use carefully the Dremel to open the sim socket - Image below. Pay attention to the ejection mechanism and let enough material on left and right edges.
- Get the required golden pins from the spare sockets by cutting them
- Remove adhesive tape
- Apply a very small amount of soldering paste below the golden pins
- Use the tweezers to place the spare golden pins on the original sim socket
- The hot air soldering station set at 250°C, low air speed, will melt the soldering paste
- Let everything cool down
- Test that new pins are soldered with the tweezers
- Adjust the heigth of the other golden pins with the new ones using the tweezers
How do I insert my SIM card?
Please follow below steps to insert the SIM card into the One:
1. Use the ejector tool to remove the SIM tray.
2. Put the Micro-SIM card in the SIM tray and make sure the card is flush with the edges of the tray.
3. Carefully make sure the SIM tray is inserted correctly, right side up, with the contact (gold part) of the SIM card facing the back side of the One. If you are using a Nano-SIM, please be aware that some adapters might damage the motherboard of the One, which is not covered by warranty. We highly recommend that you get a Micro-SIM card from your mobile operator.
4. Make sure your SIM tray is fully inserted and flush with the side of your One.
