I have had an issue a few times with my Apple iPhone not detecting the SIM Card properly. The “No SIM Card Installed” message would flash on the screen and disable many features on my phone. I tried another SIM card only to find that my iPhone didn’t detect that one either. I figured there was a hardware problem preventing the SIM card from being seen. Here’s how I handled it.
To fix this problem, you’ll have to take apart your iPhone. The process will differ depending on the model. You’ll need proper tools made to disassemble a smartphone. For instructions on your particular model, head over to iFixit.
- Remove the small screws on the side of the device. My iPhone 5c has two screws on the bottom.
- Once the screws were removed, I can use a suction cup tool to pull the screen upward.
- The SIM card slot is covered with an aluminum cover. Use a small flat-head screwdriver to pry it up.
- You should now see gold contacts that the SIM card makes contact with. Use a small flat-head screwdriver to gently pry all of the gold contacts upward.
- Snap the aluminum cover for the SIM slot back into place. I broke mine, but I did the best I could to put it back into place.
- Reassemble the device and plug in your SIM card. Hopefully it’s detected and working like a charm!
