There are several reasons why your Android device cannot read the SIM card. Some possible causes may be that you did not insert the SIM card correctly or that your Android device is having a software problem. Whatever the reason, a solution should be found quickly when your phone says, “No SIM card detected.”
Here are some fixes for the times when your Android phone cannot detect the SIM card.
If the restart fails, turn off your phone
If the cause of your SIM card error is a software issue, sometimes it only takes a simple restart to resolve the issue. Press and hold the power button until the pop-up appears with the option “Restart”. Tap on it to restart the phone.
This can solve many problems, but more recently users in the Sprint and Verizon networks have reported that a restart is not enough to fix the error “No SIM error and even restart can cause the error” No card. SIM detected. ”The solution was to turn off their phones (wait 30 seconds) and then restart them.
If this fixes your problem, you should stick to shutting down and then turning on your phone instead of restarting until an Android update or carrier settings update. be published to resolve the issue.
Switch on your SIM card
Another easy solution to SIM error in newer versions of Android is to see if your SIM card is actually on. To do this, go to “Settings -> Network and Internet -> SIM cards”, then tap the slider next to your SIM card so that it is “On”.
If you have a dual SIM setup, this is also the screen where you can make sure the SIM you want to use is activated.
Change the network mode to Auto
Another method you can try is to change the network mode to automatic mode. You can do this by going to “Settings -> Mobile networks -> Network mode” and choosing the first option, which will be LTE / WCDMA / GSM (automatic connection).
Choose the right network operator
If the network operator you are with is not the one selected in your Android device’s settings, you will definitely get the SIM card error. To make sure you have the correct one, go to “Settings -> Mobile networks -> Network operators -> Search networks”. Once your Android device has finished searching and showing the results, tap on your carrier.
Enter your network’s APN settings manually
If both of the above methods don’t work, your SIM card may have completely lost contact with the network it is supposed to connect to. If so, you may need to manually enter the APN settings from your network operator.
On a modern Android device (from 9.0 Pie), do this by going to “Settings -> Network and Internet -> Mobile network -> Advanced -> Access point names”, then clicking on the icon “+” In the upper right corner.
At this point you will either need to contact your network provider to get the necessary APN settings to enter here, or check online if your network provider is published. It might also be a good idea to take a screenshot and save your APN settings so that you can refer to them quickly if you experience any problems again.
Remove SIM card and battery
Another basic solution that you can try is to remove the battery (if it is removable) and the SIM card from the SIM card tray. Before doing this, make sure you have turned off your Android device. Once you’ve deleted everything, wait about a minute and reinsert everything again.
Dropping your phone is a common practice, but even if it hasn’t suffered any damage, the SIM card may have moved. A unique and inexpensive method that many have tried is to add paper or even duct tape to achieve a tighter fit. This usually makes the SIM card fit properly and fixes the problem.
Try to use your phone in safe mode
Unfortunately, not all of the apps you install perform well. Some apps can do more harm than good and will cause this error. Start your device in 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 apps you installed and uninstall them. Get out of safe mode and see if you continue to have this problem.
Airplane mode solution
If you’ve tried all of the basic fixes above and you’re sure the SIM isn’t to blame, it’s time to try the airplane mode fix. Swipe up from the top of your screen (once or twice depending on where you’ve placed the icon) and activate it.
Depending on the version of Android you have, you may or may not receive a warning message when you turn on airplane mode. Activate it and leave it there for about 30 seconds. When you turn it off, your Android device will start to search for a network and hopefully the SIM card error will be fixed.
Fix SIM card error by clearing cache
Clearing your Android’s cache to try and fix the no SIM card error is extremely easy. Go to “Settings -> Storage -> Internal storage -> Cached data”. When you tap on cached data, you get a pop-up telling you that this will clear the cache of all apps on your device. Just press “Delete” to continue.
If there was only one way to find out what is causing the no sim card error from the start, there would be no need to waste time trying different methods. Unfortunately, until the Android device displays a message telling you the cause, the trial and error method is all you have to do. This SIM card issue can also affect your cellular data. If you are also having an issue with your cellular data, here are the fixes.
