No SIM Card Detected,” there is no need to panic whenever you come across this error on your Android device. As this could be fixed very easily and you won’t even require a technician for this, you can fix this one yourself. Now, there could be many reasons why this error is occurring. Unfortunately, there is no way to know the exact cause of this error, except until the Android itself sends you the message stating the reason. For your guessing, it might be your SIM card that is not inserted correctly or maybe there is some issue with the software of your Android device. Whatever might be the reason, here are some fixes that you can hit and try to resolve the issue.

The Basics

If a software issue is causing your SIM card error, then most probably, a simple reboot will fix the problem. To reboot your Android device, long-press the power button until you see a pop-up window with the “Restart” option. Tap on it and your device will restart. Another thing that might be causing the error is as minor as a switched off SIM card. This generally happens with the latest Android devices where you have to switch on your SIM card from the settings. You can do so by going to Settings > Network & Internet > SIM cards. Here, toggle to slider next to your SIM card to “On” position.

Change the Network Mode to Auto

You can also try to modify the network to auto mode. To do so, go to Settings > Mobile Networks > Network Mode. Here, you will see a list of network options, select the first one which should be named as LTE/WCDMA/GSM (auto connect).

Enter Your Network APN Settings Manually

In case, the methods discussed above didn’t help you then probably your SIM card has lost contact with the network it should be connecting to. If that is the case, then you will have to enter your network operator’s APN settings manually.

On Android devices 9.0 Pie and above, you can enter the APN settings by navigating to Settings > Network & Internet > Mobile network > Advanced > Access point names. Here, click the ‘+’ icon at the top-right corner. After this, a pop-up window will appear. Here, you will have to enter APN settings. You can get these details either from your network provider or online, given that your network provider has published the details online.

Remove the SIM Card and Battery

This should have done before trying out any other method. But anyway, removing your SIM card and battery and then reinserting them will rule out the possibility of an incorrectly placed SIM card. Before doing this, please ensure that your Android device is turned off. After removing both battery and the SIM card, wait for at least one minute and re-insert everything again.

In case you dropped your phone and then facing the SIM card detection error, then perhaps, the fall has moved your SIM card out of place if not physically damaged your phone. People use a cheap and unique fix to this issue by adding some paper or tape to set the SIM card in place.

Try Using Your Phone in Safe Mode

Some applications cause more problems than good to your device, resulting in errors like SIM card not detected. Try booting your Android device into a safe mode. After a few years of being in safe mode, check if the error still occurs. If it does, uninstall the last few apps that you installed on the device and check if the problem continues. It could be possible that one of these newly installed applications are causing conflict between your device and its network connection.

Airplane Mode Solution

If none of the above methods resolves the error, then another thing to try out is the Airplane mode. Swipe down from the top of your display, and tap the airplane icon to turn it on. You may leave the Airplane mode on for around thirty seconds and then turn it off. Once off, your device will start looking for a network and if you are lucky this time, you will find that the SIM card error is fixed.

Fix the SIM Card Error by Clearing the Cache

If nothing else, clearing cache from your Android device should fix the no SIM card error. Navigate to “Settings” in your Android device. Now, tap “Storage,” then select “Internal Storage.” You will see an option named Cached Data, tap on that. After this, a pop-up screen will appear telling that clearing cache will clear the cache for all the apps on your device. Simply, tap on “Delete” to get done.

We hope that one of the above methods did hit right for you and the error do not show up anymore
