What to do if your Samsung Galaxy 20/S20+ is not detecting SIM card

When the phone is not detecting a SIM card, one of the issues could be that the card is damaged. But, sometimes, it is just some network bug or a software issue. Here is what to do:

  • We always suggest the simplest workarounds first. In this case, that’s enabling the Airplane mode. Open the Quick Settings, tap on Airplane mode, and leave it on for a minute or two. Disable it.
  • The next thing to do is a soft reset. It is super simple, and yet, it can fix so many issues without any effort. To perform it, press and hold the Power key and the Volume down key simultaneously. Hold the keys for about 5 seconds, and the phone will restart. In the ideal case scenario, no sim card error will disappear when the phone boots up.
  • Remove the SIM card and put it back in its place. When you remove the sim, make sure to check whether the card is damaged. If that’s the case, you will have to replace it by visiting the carrier. If everything is fine and the card doesn’t show any signs of wear and tear, put it back in, but make sure it is placed properly.
  • Reset network settings. By doing this, you will reset all network-related settings to factory defaults, as the name suggests. In other words, you will have to add Wi-Fi passwords all over again, pair the phone with other devices, etc. But, this simple step can fix the sim card problem on your Galaxy S20/s20+, so give it a shot. Here is what you need to do. Go to Settings > General Management > Reset > Reset network settings, tap Reset settings.
  • The issue should be resolved by now. But, if that’s not the case, another option you have is to perform a factory data reset. Make sure that you create the backup of the files first, and you’ll be ready to go. It is a process that requires a bit of time, but it can fix the issue and give your phone a new start. Navigate to Settings and then tap General Management. Next, tap Reset > Factory Data Reset. Finally, tap Reset. Wait for the process to complete. It may take a few minutes. When it is all done, you will have to set up your device as a new one.
