Samsung Galaxy Phone Not Detecting Sim Card, How to Fix?
There could be various reasons why your Samsung device cannot read or detect SIM cards. It could b just a technical glitch or a hardware case, or you didn’t insert the SIM card correctly.
Method 1: Restart Phone
Oftentimes, the issue of SIM not registering or your device not detecting the SIM card is purely due to a technical glitch. Such glitches may happen from time to time. The easiest solution to fix this is to restart your Samsung smartphone and check if the SIM is working after you restart the device.
Method 2: Enable and Disable Airplane Mode
All major smartphones come with Airplane mode, which gives you the ability to enable or disable the SIM card slot at will. Due to multiple reasons, the device might not search for networks even if the network is available. In such cases, you can first disable the airplane mode and then enable it again. This will force the device to search for nearby SIM networks and connect with them.
Method 3: Ensure You Have a Valid IMEI Number
IMEI stands for International Mobile Equipment Identity and is a 15-17-digit code on which your SIM card works. It’s important to know that your device cannot register a SIM card without a valid IMEI number.
Many users face this issue after any firmware update because the IMEI numbers get wiped off during a software upgrade or firmware upgrade. So please ensure that your device has a valid IMEI number. You can check this by dialing *#06#* on the phone dialer.
Method 4: Configure Network Mode
In our modern works, we have multiple SIM networks, including 2G, 3G, 4G, and 5G. All of this network works on different bands, and not every SIM supports all the network bands. Few SIM cards only work on 4G networks, while others can work on both 4G, 3G, and 5G services. It’s important to configure your device to enable all the network modes, so it can connect to the best available network. Follow the below steps to do so:
- Open settings and navigate to Connections > Mobil networks.
- Here tap on Mobile networks and then network mode.
- Make sure to choose the Auto to connect option along with 5G.
- This will make sure your device is connected to the best possible network available.
Method 5: Clean SIM Card
SIM cards are electronic chips with different contact surfaces your smartphone can read and communicate with. But if you often swap SIM cards on your smartphone, the SIM card may get dirty or even corroded. Please make sure you clean the card with cotton cloth with some cleaning solution. Also, inspect if the card has any physical damage or tear or wear signs.
Method 6: Enable the SIM card (Settings)
Even if you have enabled airplane mode, there is still a chance that the SIM card slot is disabled. By default, all Samsung devices are enabled access on both dual SIM slots. But due to many reasons, these SIM slows may get disabled by accident. So you can enable these SIM slots and see if it helps. Steps to enable SIM card slot on Samsung smartphone:
- Open settings and navigate to Connections > Mobile networks.
- Here tap on SIM card manager.
- Here, make sure the SIM card is enabled. If you have a dual sim mobile, you can enable both SIM cards to avoid any confusion.
Method 7: Check if the SIM direction is Correct
As our smartphones are upgrading, the SIM card size is decreasing over time. Long gone are the days when you can easily tell the direction and orientation of a SIM card. Now, most users use Nano, or Micro SIM, which are small is size and are difficult to check for orientation.
Please make sure to remove the SIM tray and see if the SIM direction is correct. If you are facing difficulty deducing the same, it could be that the SIM direction is not correct. In such a case, please connect with your SIM provider for accurate SIM instructions.
Method 8: SIM Tray is properly inserted
Gone are the days when you can pop off your Samsung smartphone’s cover to plug in the SIM card. Modern smartphones come with a SIM tray, which you can use to setup the SIM card. But due to miss handling, the SIM tray may get damaged from time to time, and this can result in multiple hardware failures. This includes multiple occasions where the SIM card is not readable.
So make sure you remove the SIM card tray, clean it properly, and ensure it is slightly without any bumps or dents. If you find any deformity in the SIM tray, please connect with Samsung care to get a new SIM tray for your respective device model.
Method 9: Test if the SIM card is Active
Whenever you buy a new SIM card, you have to activate it first in order to use it for calling and other purposes. If the SIM card is not activated, then the device will not be able to search for a network. In some devices, SIM cards are locked, and if you switch the SIM card to a new Samsung device, then you have to re-active the SIM card again. To activate the SIM, please connect with your SIM card provider.
Method 10: Examine the SIM connector
If you switch SIM cards frequently, then the SIM card connected inside the phone may get damaged or faulty. It is best practice not to switch SIM card frequency, as the inside connectors are very delicate and easy to break. To fix the connector, you can take help from a local smartphone technician, and he will fix it for you for a fraction of the price.
Method 11: Update Firmware
Another possible reason for Samsung phones not detecting Sim Card issues is a software problem. Your Samsung phone’s software may have become corrupted or outdated, which can prevent it from detecting your SIM card. In this case, updating your phone’s software or performing a factory reset may help resolve the issue.
Method 12: Reset Network Settings
If none of the above methods works for you, then you can try resetting the network settings of your smartphone. This will reset all network related settings and will hopefully fix the Samsung phone not detecting the Sim Card issue.
Method 13: Test Hardware Problem

If this is the case, you may need to take your phone to a professional repair shop to have it fixed. You can also download any hardware testing app to check for any hardware defects.
Method 14: Contact SIM Provider
If none of the above methods works for you, then the problem might be with your SIM card itself. It is possible that the SIM card is geo-blocked or needs to be activated first via the network channel. Please connect with the SIM card customer support channel; they will be able to help you further.
