The No SIM card error usually occurs when your SIM card is not inserted properly. This is the most common reason for the error but it is not the only reason why your phone may show this error. No SIM card can mean problems with your device’s software too. There is a chance that the SIM card is inserted properly but your device is not reading it because of software corruption. It may also point towards your device’s inability to check for a network.
While we can continue to explore more reasons for the problem, let us see how we can resolve the issue so that you can use your phone as usual. A phone showing this error shows that you don’t have the connectivity on your phone completely. In other words, no phone calls, no mobile data, and no messages. A smartphone may not be smart any longer with the no SIM card installed error.

Ways to resolve the No SIM card error in Android
Solution 1: Restart your device
Let us begin with the quickest and easiest way to solve the problem. When your phone restarts, it refreshes most of the software which in turn ensures that minor errors can be resolved by it. So restart your device and allow it to connect to the network once again and check if your Android device is reading the SIM. If your problem is solved then you may not have to worry about the next solutions unless restarting the device has been a temporary fix and you have had the problem return on your device very frequently.
Solution 2: Check the SIM tray
Power off your device and remove the SIM card from your Android device. There is a chance that dust built up on your phone and it is creating a problem where the SIM comes in contact with your device’s internal circuit. Blow out dust from the SIM tray and wipe your SIM gently without damaging any of its parts. Return the SIM to the tray and power on your device. Check if it is working now.
If the problem persists, try using a different SIM card on your device if you have an unlocked Android smartphone. In doing so, you will be able to confirm whether it is the SIM that is at fault or if your device needs further troubleshooting. If other SIM cards work fine on your device then your SIM is the problem. Your device is completely capable of reading SIM cards but a damaged SIM card may be causing the problem.
In this case, you must take the SIM card to your carrier.
Solution 3: Place the SIM securely on the tray
When the SIM card is not placed securely, it may end up causing this error. This is happening because every time your phone tries to connect to the network, the SIM card loses its connection with the rest of the device and causes an error. To fix this, you must apply pressure of some kind to the card slot so that the SIM can stay put.
Some users have found it easy to use tape to fix the SIM card to its position. Others have used a piece of paper to apply pressure on the SIM card so it does not move from its position.

Solution 7: Reset your device to factory settings
When nothing else works, resetting your device to factory settings can help resolve most of the problems on your device that arise from problematic software. Once your device is reset to factory settings, you will lose all forms of data and it will also delete all the third-party apps on your device. This is why it is peremptory that you back up all the data on your device before you proceed with resetting your device to factory settings.
- Head to the Settings menu of your device
- Look for Backup and Restore and tap on it

What do I do if my phone got wet and now it shows no SIM card error?
If you happened to drop your device in water and now it shows no SIM card error, there is a chance that one of the circuits may have been damaged because of the water. It is best to allow your phone to dry completely before you use it. Remove the back cover of your device, provided it is removable, take out the battery and the SIM and put the parts in a bag or bowl of rice.
Allow it to dry in the bag of rice for 24 hours before you put together all the parts of your device once again and check if the problem is fixed. If the issue persists then you must take it to a professional to check for physical damage.
What do I do if my phone shows this error after an update?
Software updates are always meant to ensure that your device works better and that it is using the most advanced technology available for the hardware. This is why it is always advised to keep your phone updated.
The updates bring many new things. You can expect new features, security patches, but that’s not all. The software updates also bring bug fixes. But sometimes, the issues may show up right after the update.
If an update ends up causing a problem, there is a chance that the old data may be creating the issue.
- Restart your device to check if the problem is gone.
- Reinsert your SIM card after wiping the SIM card and the SIM tray to ensure there are no dust particles on them. Also, make sure that the SIM does not move in the tray.
- Reset your device to factory settings after backing up the data and check if the problem is gone.
If the problem continues then take your device to a repair shop, or if it is under warranty, visit the store in which you’ve purchased it or your carrier.
