How to Fix No SIM Card Installed Error On Android Phone


SIM Card Installed


If you encounter this problem, the following are some of the steps you can take to resolve it:

Step 1: Activate The Airplane Mode

When your phone shows no SIM card installed error, you should first try to fix it by switching on your phone’s airplane mode and then switch it off again. Most times, this simple act is enough to resolve the issue.

Step 2: Reboot Your Phone

When the error occurs, the first thing you should do is reboot your phone since this resolves the issue oftentimes. This is because rebooting your phone will relaunch the phone programs and then the phone software can easily detect the SIM card once again.

It is more like your phone software trying to search for your SIM card connection afresh when it is rebooted.  If after rebooting your phone, the SIM card is still not showing, then you can move on to step 3.

Step 3: Reinsert Your SIM Card And Clean The SIM Slot

In most cases where step 2 does not work, it is usually because the SIM card was not inserted correctly, or the SIM slot has some dirt in it. And that is what step 3 will be addressing. To fix this issue, turn off your phone and remove the phone lid and battery.

In cases where the battery does not cover the SIM area, you really don’t have to remove the battery then.  Afterward, remove the SIM card, clean the SIM slot with a neat soft cloth, and fix the SIM card properly. You can then switch on your phone to see if the error has been fixed.

Step 4: Check Your Network Operator Setup

If the error persists after taking all the steps listed above, I highly recommend that you check the set up of your network operator because a wrong set up can also cause the error of a phone not detecting SIM card.

To check and probably reset the network operator setup, go to ‘settings’ on your phone, and click on ‘mobile networks.’ From there, click on ‘network operator’. After the last click, you will see an option for searching networks, click on it and wait till the search is completed, and then click on the network carrier you are currently using. That is all, go back and see if the SIM card has been detected.

If at any time your phone encounters this error, I am certain that one of the steps listed above will certainly work for you in resolving the problem.

How do you reboot your phone?

You reboot your phone by holding down the power button of that particular phone until it brings the reboot option on the phone screen.  This reboot option can read either ‘reboot or restart,’ and by clicking the option, your phone goes off and power on afterward.

How do you activate your phone’s airplane mode?

  • On your home screen, go to the notification screen and pull it down.
  • There is an airplane mode option among the options on the notification screen, click on it.
  • Then wait for a few minutes and click on it again to switch it off.
  • You can then check the SIM log to see if the SIM is now detected.

Does the SIM card installed error occur only when I get a new phone?

Although, it is common knowledge that it is only new phone users that encounter this problem, which is not exactly true. Old phones can also show no SIM card installed error especially when the SIM card has been removed and reinstalled.

How do I know when my phone encounters SIM card Error?

It is quite easy to detect when your phone develops such a problem. You will see messages on your phone saying “No SIM card”, “No Service”, “SIM Card Not Detected” and so on.
