What are the common causes of no SIM card errors?

“No SIM Card” errors on mobile devices can occur due to various reasons:

  1. Loose or Improper Insertion: A common cause is a poorly seated or loose SIM card. Ensure it’s correctly inserted in the SIM tray.
  2. SIM Card Damage: Physical damage, like scratches or a bent card, can prevent proper contact with the device.
  3. Network Issues: Sometimes, the error may not be due to the SIM card itself but network-related problems. Check network signal and connectivity.
  4. Software Glitches: Software issues, such as a corrupt operating system or a faulty SIM card reader, can lead to errors. A reboot or software update may resolve this.
  5. SIM Card Compatibility: Ensure your SIM card is compatible with your device and network. An old or incompatible SIM may not work.
  6. Account or Carrier Problems: Verify that your mobile account is active and in good standing. Carrier-related issues can trigger this error.
  7. IMSI or ICCID Problems: Issues with the International Mobile Subscriber Identity (IMSI) or Integrated Circuit Card Identifier (ICCID) can lead to errors. Re-entering these details may help.
  8. Hardware Malfunction: In rare cases, hardware damage or a malfunctioning SIM card reader can cause this error.

Symptoms of a Faulty SIM Card

Suppose you experience any of the following symptoms, beware that they are indicators that you might soon get a Sim card failure error:

Sim Card Not Ready

It is usual for an Android phone to show that the Sim card is not ready for a short period when you switch it on. However, if the Sim card is not ready display for an extended time, it might be faulty, and it’s time you replaced it.

Partial sim Contacts Display

Have you ever experienced a scenario whereby the phone book displays only phone numbers without the names you saved them with? This indicates that your Sim card is faulty and might show a failure error soon.

Phone Entering offline Mode by Itself

If your phone goes offline and back to on mode without anyone initiating it, it is a symptom that your Sim card requires a replacement before it starts displaying a Sim card failure error.

Lack of Network Coverage

Sometimes, when the Sim tray detects the Sim card, but you don’t get the network coverage, it might not be the mobile carrier issue, but your Sim card might be faulty.

How To Fix the Issue of Sim Card Failure on Android

It is an embarrassing experience when your phone can’t detect the Sim card, and you need to communicate with your loved ones. In such times, you need to maintain a cool head and try a few hacks, and you might salvage the situation. Here are some of the hacks:

1.     Activate and Deactivate the Airplane Mode

Suppose the Sim card is in good condition; turning on airplane mode and switching it off again can solve the Sim card failure on Android. When you switch the airplane mode on and off, your Android phone will be prompted to search for an available network, and most likely, your issue will be solved.

Switching the airplane mode on and off is as simple as swiping down from your phone’s display, finding the airplane mode icon, and then activating and deactivating it accordingly.

2.     Restart Your Phone

Sometimes, a temporary glitch can cause a Sim card failure. To clear the glitch, you can switch your phone off, wait for a few minutes, and then switch it on. You might be surprised that this simple hack will resolve the Sim card failure on Android.

3.     Remove and Reinsert the Sim Card

So, you have tried the first three tricks, and your Sim card still indicates the failure message? It’s time you removed and reinstalled the Sim card. Removing the Sim card is a straightforward task. However, before reinstalling, ensure it sits properly on its tray slot.

Note: When removing the Sim card, you can use the Sim card removal tool, a thin paperclip, or a pin.

4.     Enter the Network Operator’s APN Settings Manually

Sometimes a Sim card can lose contact with the network. In such an unfortunate scenario, you must manually enter the network operator’s APN settings.

You might be wondering how you should know the operator’s APN. Simple! You can check whether your operator has published its APN settings online or, better still, contact them and request APN settings.

Note: Always take a screenshot of your network operator’s APN and save it. You never know; it might be handy when you’re in trouble.

Here is how to enter the network APN settings on an Android device 9.0 pie and above:

  • Go to settings.
  • Select Sim Cards and Mobile Networks option.
  • Navigate to Access Point Names.
  • Click the “+” icon, and enter the settings.

5.     Clean the Sim Chip and Tray

Dust on the Sim chip or Sim tray might lead to Sim card failure on Android devices. Dust might lead to a loose connection between the tray and the Sim card. Therefore, if you have tried the above hacks in vain, ensure you wipe clean the Sim chip and the tray.

It could be best to use an alcohol-dampened cloth, but ensure that your fabric is soft and clean.

Alternatively, you can opt for a can of compressed air to help you blast any grime that might be hampering your Sim card from functioning as intended.

6.     Change to Auto Network Mode

Switching to auto network mode is another way to fix the Sim card failure on Android. Here is how to switch to auto network mode:

  • Navigate to ‘Settings.’
  • Select ‘Sim Cards and Mobile Network.’
  • Choose LTE/WCMDA/GSM (auto connect) option, and you are done.

7.     Ensure Your Sim Card is Switched On

Check whether your Sim card is switched on whenever you get the Sim card failure error. If you have a dual-Sim device, ensure that the Sim card you intend to use is toggled on. Here is how to switch on the sim card:

  • Navigate to ‘Settings.’
  • Go to ‘Sim Card and Mobile Networks.’
  • Toggle on.

8.     Use Your Android Device in Safe Mode

Sometimes, a third-party app can cause a Sim card failure error. To check whether your issue is app related, use your phone in safe mode for some time. If the problem disappears, you are sure that the Sim card failure error results from the latest apps you installed on your phone.

Uninstall the apps and exit the safe mode to ascertain whether you will experience the same issues.

9.     Clear Your Android’s Cache

If you have tried all the above tricks and still experience the Sim card failure on Android, try clearing your Android cache and see whether you can fix the issue.

Here is how to clear the Android cache:

  • Go to ‘Settings.’
  • Select ‘Storage.’
  • Press ‘Clear Data.’
  • Tap ‘Cached Data.’ – you will receive a pop-up informing you that you are about to clear the cache for all apps.
  • Press ‘Delete,’ and your Android cache will clear.

10. Reset Your Device’s Network Settings

Resetting the network settings should come as a last resort. Sometimes, your problem might be software related, and you cannot identify the responsible software. In such a case, you can resolve to reset your network altogether.

Resetting the network settings sets your network to default but cannot erase any data in your device.

Here is how to reset network settings on an Android device:

Go to Settings > System > Reset Options > then Reset Wi-Fi, Mobile & Bluetooth.
