If you are having an issue with the SIM card on your Poco X3 Pro device, you must turn on the Airplane Mode and then turn it off. This method does the trick most of the time, and several users have fixed the problem by applying this method only. This method disconnects your Poco X3 Pro device from the wireless system.

Toggling the Airplane Mode on your Poco X3 Pro device is pretty straightforward. Navigate to the device Settings app > Airplane Mode. Now tap on the toggle next to Airplane Mode to enable it and wait a few seconds. After that, tap the toggle again to turn it off. Alternatively, you can toggle the Airplane Mode directly from the Control Center menu.

Fix 2: Restart your Xiaomi Device

Another powerful solution is to restart your device if you encounter an issue with the SIM card or network-related issues. Restarting the device is the most workable method most of the time. In case you are facing any issues, whether they are related to software or hardware, restarting the device will fix the minor issues and glitches. Therefore, you can try this method to fix the SIM card not detected issue on your Poco X3 Pro phone.

To restart your device, follow the steps below:

Wait for a few seconds. Again, press the power button to turn the device back on.

Once you restart your Poco X3 Pro device, check whether the SIM card is showing on the screen or call your friend to know why. If the issue persists, try the other solutions.

Fix 3: Remove and Re-insert the SIM Card

Your phone can throw errors such as No SIM Card Detected, mainly when the SIM card is not properly placed in the SIM tray. For such a case, you must check whether the SIM card is correctly placed on the SIM tray on your device. Remove the SIM card tray from the left side and check if your card is properly placed. If everything is right, re-insert the SIM card in the tray and check if it’s showing on your Poco X3 Pro device.

Alternatively, you must also check for physical damage on your SIM card. Most of the time, the device will not detect the card due to damaged SIM cards. To diagnose the problem, open the SIM Card, try from the left side, and check if the SIM card has any physical damage on the card. If it’s damaged, you must replace it with the same number.

Fix 4: Re-enable the SIM Card

This has managed to give desirable results in some cases when it comes to rectifying the network settings. Therefore, if you are having an issue with the SIM card, make sure to disable and re-enable it.

Fix 5: Reset Network Settings

Some changes in the network settings might have caused the device to be unable to detect a SIM card. However, there are useful features available on Poco X3 Pro devices that can reset the network settings, which may help you to refresh the network connection and other issues related to SIM cards. By resetting the network settings, you may lose access to Wi-Fi passwords, paired devices, Bluetooth, etc.

To reset the network settings on your Poco X3 Pro device, follow the steps below:

Open Settings app on your device.
Tap on Connection & sharing.
Scroll down and tap on Reset Wi-Fi, mobile networks, and Bluetooth option.
Finally, tap on Reset settings. You will have to enter your device passcode to proceed with the reset process.

Fix 6: Perform a Factory Reset

If you have tried the above solutions and they don’t work, you must perform a factory reset on your Poco X3 Pro device. This method often works with software-related issues, so try this method if you are having an issue with the SIM card on your device. By factory resetting your device, you will lose all your data, including photos, videos, and documents. Therefore, take a complete backup of your phone before using this method. Here’s what you need to do.

Open the Settings app on your device.
Scroll down and tap on Additional Settings.
Scroll to the bottom, and you will see the Factory reset option.
Tap on Factory reset and select Erase all data.
Enter your device passcode to confirm the reset process.

Once you have proceeded with the factory reset process on your Poco X3 Pro device, it will take several minutes to turn it back on. So be patient until your device turns back on. After that, you must set up your device by following the screen instructions. Then, check if the SIM card is showing on your device.
