Understanding the SIM Card and Its Function
Before diving into troubleshooting, it’s essential to understand what a SIM card does and how it plays a crucial role in the functionality of your smartphone.
What is a SIM Card?
A Subscriber Identity Module (SIM) card is a small plastic card inserted into mobile devices. It connects your phone to a mobile network and stores important data like your phone number, carrier information, and contacts. Without a properly functioning SIM card, your phone cannot connect to the network, resulting in issues such as calls not going through, messages failing to send, or your device not recognizing the network.
Common Symptoms of a Faulty SIM Card
The symptoms of a malfunctioning SIM card can vary, and recognizing these issues can help you address them quickly. Here are a few signs that your Samsung S23 Ultra’s SIM card might be the culprit:
1. No Signal or Weak Signal
One of the most apparent signs that your SIM card is not working correctly is when you notice no service or weak signal bars. You may see “No SIM” or “Searching for network” displayed on your screen.
2. Error Messages
You might encounter error notifications such as “Invalid SIM” or “SIM Card not detected” when you attempt to use mobile data or make calls.

Scroll down and select “General management,” then tap on “Reset.” Here, you will find the option for “Reset network settings.” Once selected, confirm your choice, and the device will reset all settings related to Wi-Fi, mobile data, and Bluetooth.
It’s important to note that resetting network settings will erase all previously saved networks, passwords, and VPN settings. Therefore, ensure that you have any necessary credentials handy to reconnect afterward. This process may help resolve connectivity issues related to your SIM card and restore normal functionality.
Why is my Samsung S23 Ultra showing “No SIM card” even with a SIM inserted?

How to check if my SIM card is faulty on the Samsung S23 Ultra?
To determine if your SIM card is faulty, you can try using it in another phone. Insert the SIM into a different compatible device and check if the SIM card works. If it functions properly in another phone, the SIM card is likely fine, and the issue may reside with your Samsung S23 Ultra. If it doesn’t work elsewhere, the SIM card may be damaged or deactivated.
Another way to check for faults is to inspect the SIM card for visible damage, such as scratches or bends. Also, reach out to your mobile carrier to verify if the SIM card is active and if there are any reported issues in your area. They can also replace the SIM card if needed, which often resolves ongoing connectivity issues.
What if my Samsung S23 Ultra SIM card works intermittently?
If your SIM card is working intermittently, this could indicate issues with either the SIM card or the device itself. Begin by checking the SIM card for any signs of physical damage, as even minor scratches can affect connectivity. Removing the SIM card, cleaning the metal contacts gently with a soft cloth, and reinserting it can sometimes help restore stable connectivity.
If the problem persists, consider updating your phone’s software to the latest version. Manufacturers often release updates that resolve bugs affecting hardware performance, including SIM card functionality. If updates do not resolve the intermittent issue, seek assistance either from Samsung support or your mobile carrier for more thorough diagnostics and support.

Yes, a software update can often resolve issues related to SIM card functionality. Manufacturers regularly release updates that come with bug fixes and improvements, which may address specific problems affecting connectivity. To check for updates, go to “Settings,” then “Software update,” and select “Download and install.” If an update is available, ensure your device is charged or plugged in before proceeding.
After updating, restart your device to apply changes fully. This process not only refreshes your device but also allows it to recalibrate its connections, potentially resolving any persisting SIM issues. If problems remain even after the software update, further troubleshooting or professional support may be necessary to determine the root cause.
Is it possible to fix a SIM card not working issue on my Samsung S23 Ultra myself?
Yes, many SIM card issues can be diagnosed and sometimes resolved by users. Start by troubleshooting common problems such as checking that the SIM card is properly seated, making sure there’s no debris in the SIM slot, or trying a different SIM card to see if the problem lies with the card itself or the phone.
