The last thing you want is a SIM failure on your iPhone before making an urgent phone call.

If you are bothered due to such an error and looking for a solution, this article is your guideline.

So, keep reading and learn the reasons and solutions to SIM card failures on your iPhone.

Reasons for SIM Failure on iPhone 

Before we look into the solutions to fix the SIM failure on iPhone, let’s learn the possible reasons for it.

Obviously, the reasons can either relate to the hardware or software of the faulty iPhone.

That said, we intend to list down the most common reasons for your iPhone to experience SIM failures.  

  • In some cases, the issue may relate to nothing but the SIM tray itself. For instance, if your device’s SIM tray has dust or if it is placed incorrectly, there can be issues. In addition to that, SIM failure on iPhone can occur when the SIM tray hasn’t closed properly. The iPhone cannot recognize the SIM even if you insert it.
  • If your SIM card has some physical defects (damages), you are likely to experience issues.
  • If the iPhone has other isolated errors, it can lead to SIM failure errors. In order to check if the respective error is related to iPhone itself, you should force restart the device.
  • The OS version may have several bugs that may lead to various SIM card errors. In that case, you can either downgrade or upgrade iOS issues and check the potential glitches.
  • Your iPhone itself might have some hardware issues, and those errors will eventually trigger SIM card malfunctioning.

Besides, if you come across SIM not provisioned for voice on your device and looking for solutions, we explain the most appropriate fixes you can try.

Solutions for SIM-Related Issues on Your iPhone

Many iPhone owners are frustrated by the “SIM failure” warning. Is your iPhone giving errors like “SIM card failure,” “no SIM card installed,” or “Invalid SIM“? If so, try the following common solutions.

If you’re having trouble with your iPhone’s SIM card, try the following.

  • Check if you have an active plan with your network carrier. If it is not active at the moment, you are likely to experience SIM failure on your iPhone.
  • Check if you have any new updates from your service provider. In many cases, outdated iOS devices are likely to give various errors, including SIM failure on iPhones. So, it is mandatory to update your device to the newest possible version to prevent unwanted errors. Go to “Settings” and select “General.” Then, go to “About.” Now, you will see any available updates. If you don’t see any updates, make sure that you install them.  
  • Turn your iPhone off. After that, switch it on again.
  • Inspect the iPhone’s SIM card slot. There are issues with the phone’s closure if you use a SIM tray designed for a different version. Try re-inserting your SIM card after you’ve removed it and double-check that the SIM slot is closed properly.

  • You must check for available updates in your iOS version. For instance, if there are carrier updates, you better install them. Updating the iOS to the most recent version will help you fix many minor issues, including SIM failures.
  • Make sure that you use a different SIM if none of the above solutions have worked for you. In some cases, the issue can be directly related to the SIM’s physical condition. For instance, your SIM may have small dents or cracks in it that can hardly be seen. If you cannot find an extra SIM, you can request a new one from your carrier. Then, you should see if it works with the iPhone.

And those are the most basic solutions you can try if you experience SIM failure on your iPhone.
