How to Fix No SIM Card Detected on Android

There are various reasons why your Android device won’t read the SIM card. Some possible causes could be that you didn’t insert the SIM card correctly, or your Android device is experimenting a software issue. Whatever the reason is, a solution needs to be found quickly.

Here are some fixes for those times when your Android phone can’t detect the SIM card.

If what’s causing your SIM card error is a software issue, sometimes a simple reboot is all it takes to fix the problem. Long-press on the power button until the popup window appears with the “Restart” option. Tap on it to restart the phone. If the phone doesn’t come with a “Restart” function, then power it off, wait for thirty seconds, then turn it on again.

Wait until your Android device tries to connect to the network again, and hopefully you won’t see the SIM card error anymore. If you still see the error message, try the following methods.

Another basic fix you can try is removing the battery (if it is removable) and SIM card. Before you do this, make sure you’ve turned off your Android device. Once you’ve removed everything, wait for about one minute and re-insert everything again.

Dropping your phone is a common practice, but even if it didn’t suffer any damages, the SIM card could have moved out of place. A cheap and unique method many have tried is adding some paper or even tape to get a tighter fit. That usually makes the SIM card fit nice and tight and resolves the problem.

Unfortunately, not every app you install plays nice. Some apps can cause more harm than good and cause this error. Boot your device into safe mode.

Stay in safe mode for a few hours and see if you continue to have this problem. If not, try to remember the last few apps you installed and uninstall them. Get out of safe mode, and see if you continue to have this problem.

If you’ve tried all of the above basic fixes and you’re sure that the SIM card is not to blame, it’s time to try the Airplane mode solution. Swipe down from the top of your display (once or twice depending on where you’ve placed the icon), and turn it on.

Depending on the Android version you have, you may or may not get a warning message when turning Airplane Mode on. Enable it and leave it on for about thirty seconds or so. When you turn it off, your Android device will start looking for a network, and hopefully, the SIM card error will be fixed.

Modifying the network mode to auto is another method you can try. You can do this by going to “Settings -> Mobile Networks -> Network Mode” and choosing the first option, which will be LTE/WCDMA/GSM (auto connect).

Clearing your Android’s cache to try and fix the no SIM card error is extremely simple. Go to “Settings -> Storage -> Internal Storage -> Cached Data.” When you tap on cached data, you’ll get a popup telling you that this is going to clear the cache for all the apps on your device. Just tap on “Delete” to go through with it.

If the network operator you’re with is not the one that’s selected in your Android device’s settings, you’ll definitely get the SIM card error. To make sure that you have the right one, go to “Settings -> Mobile Networks -> Network Operators -> Search Networks.” Once your Android device is done searching and displays the results, tap on your carrier.

If there were only a way to know what is causing the no SIM card error from the very beginning and to not have to waste time trying different methods. Unfortunately, until the Android device shows a message telling you what the cause is, the trial and error method is all you have. What’s the first method you try when you get this error?

  1. The message I’ve got each time is” no sim card is detected on nenetwork” but actually there is a som card in there

  2. Thanks for the article. I tried all the methods in the order you’ve listed. It did not fix my “No sim card” issue until, I tried, “Change the Network Mode to Auto”. After this, the error message went away. So thanks again, my phone is now fixed. I hope
    the error doesn’t come back.
