Why do I see the SIM card not working or SIM card not detected message?

Furthermore, the SIM card not detected notifications can also differ between Android and iOS devices. We will take you through both the methods so that you get more clarity.

SIM card not detected message in iOS devices

If you have an Apple device, these are some of the steps that you should follow if you are seeing an invalid SIM message:

1. First of all, make sure you have an active plan with your network carrier. There can be many instances when your current plan has expired, and that is why you are seeing the invalid SIM message popping up. Simply go to your carrier’s website and make the desired recharge. Your network will be back up in almost no time.
2. In case, the mobile operator’s plan is not functional, then you can also try to restart your iOS device. It ideally works out if there are any underlying and minor issues that maybe affecting your device temporarily.
3. Furthermore, if the previous step doesn’t work out, try looking for an update. You need to check for an update to the mobile carrier settings. Open the Settings app on your smartphone, go to General and then About section. If any update is available, click on the button and go ahead with it. The update should fix any of the issues with the SIM not working message.
4. Next, try removing your SIM card from the device and inserting it once again. While inserting the SIM card, make sure that you are placing the SIM tray perfectly. It should not be left loose.
5. As a last resort, try to see if another SIM card is working. If it is, then there is an issue with your SIM card itself. You might have to replace your SIM card now that the previous one is not working anymore.

These solutions will end up fixing your iOS device and you can get going once more. However, if not, then it is time to approach your local Apple service centre and get things sorted out from there.
