How to troubleshoot Sony Xperia L2 with No SIM card detected error

Before you begin troubleshooting, verify and ensure that you are using the right SIM card type. The Xperia L2 supports nano SIM cards. If you just got your phone and are using the same old SIM card, then you may need to contact your carrier for new SIM card replacement.

First solution: Restart your phone (soft reset).

When you restart your device, all running apps are shut down. This therefore can free up memory. Should the error is triggered by some errant apps, a restart or soft reset will fix it. That said, restart your Xperia L2 with these steps:

  1. Press and hold down the Power key for a few seconds until the menu opens.
  2. Tap Restart from the menu options. Doing so will trigger the device to restart automatically.

A soft reset or restart will not affect data saved in the internal memory, therefore there is no need to worry of losing personal information.


Second solution: Remove and reseat the SIM card.

Your device might be telling you that the SIM card is not properly seated, and so it could not detect it. To rule this out, you can remove the SIM card and ensure that it’s properly seated. Here’s how:

  • Turn your phone off.
  • Gently drag out the SIM card tray.
  • Remove the SIM card from the tray and check for any visible signs of damage like scratches or dents. If there’s none, then place it back into the card slot in the correct orientation.
  • Gently push the tray back into the slot until it fits and locks into place.

Your phone has separate slots for the nano SIM card and the memory card (SD card). Your device will definitely not detect the SIM card if you placed it in the wrong slot. Make sure you don’t confuse the two.

Third solution: Reset network settings on your Xperia L2.

Performing a network settings reset will restore network feature to their default configurations. Affected settings are Wi-Fi, Bluetooth and mobile data. This will help fix network-related issues that are inflicted by invalid network options or settings modification on the phone. Should you wish to give it a shot, then proceed with these steps:

  1. Navigate to Settings-> Network & Internet menu.
  2. Tap the three vertical dots or Menu icon.
  3. Select Network settings reset from the given options.
  4. Tap Reset Settings to confirm.

This will clear all connection data. After the network settings reset, your device will reboot. By then you can set up your wireless network and other network features again.

Fourth solution: Update software to the latest version.

To ensure that your device has optimal performance and latest enhancements, update the software to the latest version available. You can check new software update on your Xperia L2 with these steps:

  1. Navigate to Settings.
  2. Tap About phone.
  3. Tap Software Update.

An update notification will let you know if a new software is available for your device. Follow the onscreen instructions to download and install the new software. Otherwise, it will tell you that your device is up to date.

Before you download and install any software update, be sure to back up your important data for safekeeping. Also make sure that your device has ample of storage or memory space to allocate the update file. Lastly, your phone must be connected to the Internet and has enough power left to complete the entire update installation process. Don’t forget to reboot your phone once it’s done installing the new software update. Doing so will ensure that the new changes are properly implemented. If your phone is acting weird after the new update is implemented, wiping cache partition is needed.

Fifth solution: Reset your Xperia L2 to its factory defaults (master reset).

If your Xperia L2 still cannot detect the SIM card after performing the aforementioned procedures, then you may have to resort to a full system reset already. The problem could be due to a complex bugs or malware that might have corrupted the network system. Major software issues like this are usually remedied by wiping the device. This however will result to data loss, hence creating a backup is needed. If you think it’s worth a shot, then you may proceed with these steps:

  1. Create a backup of your important data stored on the internal memory.
  2. Navigate to Settings.
  3. Tap Backup & reset.
  4. Select Factory data reset from the given options.
  5. Tap Factory data reset to continue.
  6. If prompted, enter your lock screen credentials or unlock password or PIN.
  7. Tap Erase everything to confirm and instigate full system reset.

Wait until the reset is finished and your phone reboots. Everything will then be restored to the default configuration. Set up your device as new then. Any previous software issues should be fixed afterwards. But if you’re still getting the same SIM card error, then your phone probably needs service.

Other options

Contact your network service provider/carrier if your Sony Xperia L2 still cannot detect the SIM card and the No SIM card detected error persists after performing all applicable workarounds. If possible, try to request for a new SIM card replacement. There is a higher chance that your current SIM card is damaged and therefore not working. Try to insert your SIM card in another compatible device. If it works on your other device, then it is probably your device that’s causing the problem. Since you’ve already performed all applicable solutions to deal with software errors that might have prevented your device from reading the SIM card, then you may have to consider opting for service this time. In this case, contact the nearest Sony Mobile service center and set up a service appointment.
