21 Best Ways To Fix The “No SIM Card Detected” Error On Your Smartphone

Are you suffering from the “No SIM Card” or “SIM Card Not Detected” error despite having a SIM card plugged in? If you are, then you’ve come to the right place.

I know how you feel, and it’s frustrating. If your Android phone has any trouble reading your SIM, check the placement of your SIM card. If you’re wondering why: most SIM detection errors in phones are due to improper insertion of the card. Although this isn’t always the case, you might want to check the position of your SIM card first.

Without further ado, here are 21 different ways to fix “No SIM Card Detected” issues on Android phones or tablets.

1. Reboot Your Device

Restart your Android device. If you just inserted a new SIM, many phones won’t recognize it until you restart the device.

This method is probably the simplest way to resolve minor problems of any kind when it comes to your Android device.

2. Remove The Battery. (If possible)

Turn off your phone and unplug it from any power source. Remove the battery and wait 30 seconds or more.

After doing so, put the battery back in place and turn on your device. This method power cycles your device and eliminates many probable causes of errors.

3. Adjust The SIM Card

The SIM card must be seated in your Android properly. Your SIM card is what connects you to your network, so this is crucial to solve the ‘No SIM Card Detected’ error.

If you accidentally dropped your Android, the SIM can become misaligned, or it may not have been installed correctly from the start. Make sure to place the SIM securely into your device.

If the SIM doesn’t fit well in your phone’s slot, you can try placing a tape, cardboard, or paper into the tray for a tighter fit. Although it might seem like a cheap fix to your SIM problems, this method works for many to avoid no sim card detected notifications.

Also, be careful in handling your device. Never use too much force to avoid damaging your Android phone.

4. Manually Select Carrier/Network Operator

Sometimes, your settings will change all of a sudden due to updates. This change can sometimes cause the network to disconnect.
