Many Android customers have encountered the problem of Invalid Sim Card android and are curious as to why it occurs and how to resolve it. Don't worry if you've fallen into this problem; I've put together a list of the best solutions to fix the "Invalid SIM card" error in Android. I hope that by following them, you will be able to fix the problem.
What is the meaning of Invalid Sim
The invalid SIM card problem means the device doesn't have a SIM card, the connection isn't working, or the SIM card is loose. As a result of these very common factors, your sim card is not working. It doesn't matter why you're getting this error message; it is because your SIM card and it's tray are connected.
What exactly causes the Invalid Sim Error
Have you ever wondered why an error message appears on your Android screen? Okay, I'd want to point you that there are two locks on your phone that could cause this error message. Few people are aware of the phone's two locks. Network locks and region locks are the two sorts of locks.
Network lock
It implies you'll be unable to use any SIM card other than the one that came bundled with the phone. This lock is implemented by network carriers, not by phone manufacturers or Google. If you like, you can unlock after reading a few words.
Region lock
This security feature is provided by your smartphone's manufacturer. It means that if your SIM card is from a different nation or region than your phone, it will not work.

Now I'll show you a couple different ways to fix the no SIM card issue message on an Android phone. Do not be alarmed if you encounter such an error notice; simply follow the steps outlined below.
10 Surefire ways to fix Invalid Sim Card error in Android
1. Hit the Restart button
To make the sim card work again one of the easiest and simplest solutions to fix the no SIM card issue notification is to restart your Android device. Many annoying faults on phones can be fixed by restarting the system, which completely refreshes the device and cures small errors rapidly. If the network is unavailable, this will allow your device to reconnect, and you may now check to verify if the SIM card is properly identified. Furthermore, this procedure will enable you to resolve the issue where the phone does not recognize the SIM card. If the problem continues, then move on to the next step and try the other remedies.
2. Check the Sim Card tray
One of the most typical causes of the error message is damage or breakage of the SIM tray. If it's broken, fix it with a piece of foam. Remove the back cover and place it over the SIM card, then restore the back cover.
The error "invalid SIM card" implies that your SIM card is having trouble recognizing it. Simply turn off your Android phone and check to determine whether the SIM card is faulty. It is better to use a legitimate SIM card and double-check that everything is operational. This will help you ascertain if the problem is with the SIM card or the tray.
3. Turn on/off Airplane Mode
If you're sure the issue isn't with your SIM card, try switching your phone to Airplane Mode. This is primarily due to the fact that many users have found it useful. Simply follow the procedure outlined below to do so:
To begin, bring down the notification screen on your Android phone. Then search for the icons for Airplane Mode. Just click on it to turn it on. A message of caution will appear; simply click on it. Finally, wait 30 seconds before turning off Airplane mode by clicking on it again. After you make this adjustment, your phone will check for a network again, and if it is successful, your problem will be rectified.
4. Reinsert Sim Card
As I previously stated, this can arise as a result of a faulty or loose link, so I have a better solution. Simply turn off your Android device, disconnect the charger, and insert a new SIM card. Another way to get rid of the no SIM card errors alerts on your phone is to use this method.
5. Select the correct Network Operator
This issue occurs if the network operator selected does not match the settings on your Android phone.
To make sure you're using the correct network operator, click to Settings > Mobile Networks > Network Operators > Search Networks.
After that, your smartphone can look for a network and select a carrier from the list of available options.
6. Get a new Sim Card
Even after reconnecting your Android phone's SIM card, you may obtain the same error message. Check to see if your SIM card is affected if this is the case. So go out and purchase a new SIM card, connect it to your account, and see if your phone can detect it. If a new SIM card detects and works, the old one is defective and should be replaced. Your phone, on the other hand, has an issue if a fresh SIM card does not work. In this instance, you will require technical assistance through your phone's service center.
7. Select Auto Network mode
If your Android phone is set to the wrong network mode, you'll get an error message like this. This happens when your phone fails to connect to the correct network. This is what happens when your phone fails to select the correct network. Set your network mode to auto to get rid of the error message. Follow the steps outlined below to get started:
To begin, go to the Settings menu on your phone. Look for more networks under Connections and click on them. Then, under Mobile Networks, select Network Mode. A pop-up window will spring open with multiple options. Make sure to select the first option. When you make this change, your device will automatically connect to the nearest available network. If you make a mistake, your phone will display No SIM Card problems.
8. Clear Cache in Storage to fix the Invalid Sim Card error
The error message you're getting might also be resolved by clearing the cache on your Android phone. To do so, navigate to Settings > Storage > Internal Storage > Cached Data. After clicking on cached data, you'll see a window that states "clean cache for all apps on your devices." Then press the "Delete" button to continue.
9. Try out the Safe Mode technique
Third-party apps can also cause your Android phone to display the error "No SIM Card." Simply enter Safe Mode on your Android device. If the error is no longer occurring, the problem is most likely with the third-party software you've installed. Simply uninstall any recently installed software to avoid obtaining such an error notice.
10. Final Option - Factory reset or simply put, nuke your phone
If none of the other options work, your device's sole remaining option is to conduct a factory reset. If you reset your phone to factory settings, all of your data and third-party apps will be erased.
As a result, please make a backup of all of your vital data before proceeding, and then follow the procedures below:
- To begin, go to the Settings section of your phone.
- Find Backup and Restore and select it.
Before resetting your app, don't forget to choose Backup, which will save all of your app's settings. Also, make sure that Automatic Restore is selected so that settings are restored automatically after a factory reset. From the drop-down menu, choose Reset Phone. After the system has been reset, it will reboot automatically, and you may check to see if the fault has been resolved.
