Why is my phone not reading my SIM card? There are various reasons for not recognizing the SIM card in Android. Sometimes this is due to a malfunction of the SIM card or it may even be due to software malfunctions. Whatever the reason for this, we have found a solution for it in Wironal. So if your phone is having this problem recently, you are in the right place. In the continuation of this article, join us to guide you step by step in solving the problem of not recognizing the SIM card in Android.
Reboot or turn off the phone
If the problem of not recognizing the SIM card in Android is due to a software glitch, sometimes a simple reboot will completely fix it. All you have to do is hold down the phone’s power button until a pop-up window appears on the screen with the “Restart” option. Now click on this option to restart your smartphone.

Doing a simple reboot will fix many errors and disturbances in your phone, but recently users have reported that just doing a reboot is not enough to solve the problem of not recognizing the SIM card in Android, and you may even get an error message “No SIM card detected” Face. If you encounter this problem, just turn off your smartphone for 30 seconds and turn it on again.
If this method solves the problem, you should always use the method of turning off the phone instead of rebooting when facing telecommunication problems or Android updates.
Turn on your SIM card
Another simple way you can solve the error of not recognizing the SIM card in Android is to check to make sure your SIM card is turned on. To use this method, just go to “Settings -> Network & Internet -> SIM cards” and then turn on the slider next to your SIM card to make sure it is enabled.
If you use the dual SIM settings of your Android device, this method will make sure that the SIM card you want is also turned on.

Change network mode automatically
Changing the network mode automatically is another method that you can use when dealing with the problem of not recognizing the SIM card in Android. To use this method, you can first go to the phone’s Settings section and select Mobile Networks from the menu. Then click on Network Mode and select the first option or LTE / WCDMA / GSM (automatic connection) to complete this step.

Select the network operator correctly
If the network operator of your SIM card is not the same as the operator you selected in the settings of your device, you will definitely encounter the error of not recognizing the SIM card in Android. To ensure that this option is selected correctly, you must go to “Settings -> Mobile Networks -> Network Operators -> Search Networks” and after completing the search of your Android device and displaying the results, select the desired telecommunication network correctly.

Manually enter your network APN settings
If the above methods do not solve the problem of not recognizing the SIM card in Android, it is likely that your SIM card has completely lost its connection to the network to which it must be connected. If this happens to you, you must enter your network operator APN settings manually.
On modern Android devices (Android 9 and above) do this by going to “Settings -> Network & Internet -> Mobile network -> Advanced -> Access point names” and clicking on the “+” icon in the upper right corner It will be done right.

Remove the battery and SIM card
Another simple way to fix the error of not recognizing the SIM card in Android is to remove the battery (if it can be removed) and your SIM card from the SIM card slot. Before doing this step, you must make sure that your Android device is turned off. After removing everything, wait a minute and reinsert the battery and SIM card.
Losing your phone is a common occurrence that every user experiences at least once, but you should be aware that if there is no damage to your phone, the SIM card may come out of its case or move it. One simple and inexpensive way to prevent this from happening is to use a piece of paper or duct tape to secure the SIM card in place, which you can use. This will allow the SIM card to adhere to the entire compartment and fit snugly in place and you will no longer have this problem.
Try Safe Mode
Unfortunately, not every app you install on your Android phone works well. Some applications can cause the problem of not recognizing the SIM card in Android. If one of these programs is installed on the device, putting the phone in Safe Mode can help solve this problem.
It is best to keep your phone in this state for a few hours to see if the problem of not recognizing the SIM card will continue or not. If the phone problem is solved, remember some apps that you have recently installed on your device and delete them. Finally, you can take the phone out of Safe Mode to see if the problem persists.
Solution to use Airplane Mode
If you have tried all the above methods and of course, you are sure that there is no malfunction of your SIM card and the SIM card is completely healthy, it is time to use Airplane mode. To do this, simply drag the screen of your phone from top to bottom and click on the aircraft icon (as shown below) and activate it.

Depending on the version of Android you are currently using, you may receive a warning message when you turn on Airplane Mode. We recommend that you turn your phone on for 30 seconds or more after activating this feature. After disabling Airplane Mode, your Android device will search for a network. We hope that using this method will solve the problem of not recognizing the SIM card in Android.
Fix SIM card error by clearing the cache
Clearing the Android cache is a very simple but practical way to fix the error of not recognizing the SIM card in Android. All you have to do is go to “Settings -> Storage -> Internal Storage -> Cached Data” and after clicking on the Cached Data option, a pop-up will appear telling us that this is the cache of all applications. The content on your phone will be deleted. Just click on the “Delete” option to complete this step.

If there was a way to tell us from the beginning where the error of not recognizing the SIM card in Android comes from, we would not have to waste our time trying any possible method. Unfortunately, until technology advances so much that Android phones can tell us exactly where the problem is, we have to try and find the root of the error ourselves using trial and error.
