One of the most commonly reported issues with Android devices is the dreaded “No SIM card” error message This problem can be quite frustrating since you can’t make calls, send texts, or even access the internet when it’s in that state.

Android No Sim Card Detected [Try These Fixes]

You might have tried restarting your phone and looking for clues in your settings menu, but nothing works. The error message can result from several different causes, but unfortunately, there’s no single solution that’ll fix it for everyone.

In this article, we’re going to take you through the steps to troubleshoot your specific situation so you can get back up and running in no time.

Recommended Solutions when No SIM Card Detected

Solution 1: Reboot Your Device

The first step in attempting to fix the issue is restarting your phone. Android systems are designed to attempt repairs and solve software issues whenever your boot up. To restart your phone:

  1. Press down the power button and then select “Restart” or “Reboot” from the pop-up menu.
  2. Confirm your choice on the pop-up screen.
  3. Give your device time to power back up again.

When you boot up, your phone will attempt to re-establish a connection with your network provider, and this will initiate a new search for your SIM card.

After rebooting, you should also be on the lookout for any messages from your carrier that may have instructions on fixing the issue. It’s not uncommon for carriers to experience technical glitches that culminate in network failure.

Solution 2: If Reboot Fails, Shut Down Your Phone

In most cases, rebooting your device solves the problem. However, it may not. Some Android users have reported that the “No SIM Card” error message persists even after restarting their devices. If this happens to you, don’t fret. Shutting your device and waiting at least 30 seconds before powering it back up can be the solution. To shut down your device:

  1. Press down the power button and then select “Turn off” or “Power off” from the pop-up menu, depending on the type of device you’re using.
  2. Confirm your choice on the pop-up screen.

You may also need to unplug your device from any power source. If you want to be even more thorough, you may want to remove your battery as soon as you power off your device.

When you power off your phone, it terminates all connections with cell towers, and its radios are turned off. When you power back on, your system initiates connection sequences afresh. In the process, any temporary glitches or network errors may be solved.

Solution 3: Adjust the SIM Card

Your phone can only read your SIM card if the SIM card is firmly seated in its slot. If the card is dislodged or misaligned, which can occur after you drop your phone accidentally, you won’t be able to connect to your carrier. Or, if your device is new, you may not have inserted the SIM card correctly. Thus, the next troubleshooting step should be removing the SIM card and inserting it back in.

While you’re doing this, ensure that the SIM card fits securely into your device. If it appears loose, you may want to try placing a piece of tape, cardboard, or paper into the tray to achieve a tighter fit. Although it may appear as an unconventional fix, adjusting the SIM card in this way works for many Android users.

As a rule of thumb, you should avoid applying too much pressure when handling your phone’s interiors. Excessive force can damage your device’s hardware and create new problems.

Solution 4: Remove, Clean, and Re-Insert Your SIM Card

Adjusting your SIM card won’t solve the “No SIM Card” error if the SIM tray is filled with dirt or grime. For best results, here’s how you should clean your SIM card and SIM card slot:

  1. Power off your device.
  2. Find the SIM card tray on the inside of your device.
  3. Open the SIM card tray and pull out your SIM card. While doing so, be careful not to use excessive force. Also, the SIM card tray may not be accessible on some devices. If you’re not sure how your device’s tray works, check the documentation for your device.
  4. You’ll want to clean the Sim card slot with a small brush or tissue swab. If you’re not sure what kind of brush to use, go for a very small and soft microfiber cloth. You can use an airbrush cleaner as well if you have one available. The cleaner works best after the first round of soft scrubbing to remove any dirt and grime that may still be stuck in the SIM card tray. Also, make sure that nothing insertable (like a toothpick or paperclip) blocks your SIM card assembly area.
  5. Clean your SIM card using a soft microfiber cloth. You may soak the cloth in rubbing alcohol or some other non-conductive spray. Once all dirt and grime are cleared, make sure you dry off any excess liquid before sliding the SIM card back in.

After cleaning and re-inserting your SIM card, you should power your device back on and check whether the problem is solved.

Solution 5: Clear the Cache Data

Although clearing cache data is usually recommended when there’s a malfunctioning app, it can also solve SIM card errors. Sometimes cache data gets corrupted, a situation that can cause all manner of performance problems for your device. Clearing your cached data can fix network crash bugs or force your device to reallocate memory resources, leading to a reconnection to your carrier.

Here’s how to clear cache data on Android devices:

  1. Open Settings.
  2. Navigate to “Storage.”
  3. Open “Internal Storage.”
  4. Tap on “Cached Data.”
  5. Confirm that you want to clear cached data in the dialog box that appears.

Solution 6: Switch on Airplane Mode

There’s always a chance that the “No SIM Card” error message has nothing to do with your SIM card. To find out if the SIM card is working, you should try inserting it into a different phone. If it receives signals in the new phone, your signal problem could be miscommunication between the nearby cell towers and your original device. In this situation, Airplane mode can be the solution.

When you activate Airplane mode, you turn off all wireless radios on your device, including cellular radio, Wi-Fi, and Bluetooth. Communication with cell towers is cut off immediately. Your device is forced to re-establish a connection when you leave Airplane mode.

To activate Airplane mode on your device,

  1. Swipe down (or up) to open the notification screen.
  2. Tap on “Airplane mode” or “Flight Mode.”
  3. Confirm that you want to activate Airplane mode in the dialog box that appears.

After a minute or two, you should exit Airplane mode and then check whether your SIM card is now readable.

Solution 7: Choose Network Operator

An undetectable SIM card can be extremely frustrating. You could miss business meetings, appointments, or fall behind on the emerging issues for hours. Before getting a new SIM card, you should try choosing your network manually.

If your device is set to a different network operator than the one you’ve chosen, the “No SIM Card” error is inevitable. Here’s how to make sure you have the correct network settings:

  1. Open Settings.
  2. Navigate to “Mobile Networks.”
  3. Tap “Search Networks.” Your device will take a few moments to search all available networks and then display the results.
  4. Tap the carrier you’re currently with. Your device will then set it as the preferred network.

Solution 8: Replace Your SIM Card

If you’re getting the “No SIM Card” error, physical damage to your SIM card could be the culprit. In this situation, you should get a new SIM card from your preferred carrier. You will still be able to keep your phone number, but you may lose your data.

Solution 9: Reset Device to Factory Settings

If none of the solutions we’ve outlined works for you, consider resetting your device to the factory settings. However, resetting your phone will erase all the data you’ve accumulated over time, and you’ll also lose any customized settings. Thus, you should back up your data before initiating the reset.
