Fix, No Sim Card Detected or Not Recognized error on OnePlus 8 Pro

Check the Error

These days error detecting is getting better day by day. Error codes or messages are usually key to solving problems. If your messaging app displays an error every time it fails to send texts, be sure to take note of it. Then, do a Google search about the exact message or code and see if there’s any available online solution.

Forced reboot

Well, I think you already know how to restart your phone. So just restart the device and see whether it solves the issue or not. Restarting a device is always an ultimate solution for any issue.

Well if you still need to know how to restart then, here is it: Press your phone’s power button. On the screen, tap Restart.

The other way of the reboot is as follows:

  • Press and hold down the Power and Volume down buttons at the same time.
  • Hold the Power button down for 10-15 seconds, or until the phone vibrates and restarts.
  • If the phone turns off let go then press power again for 1-2 seconds to restart the phone.

Remove and Reinsert SIM card

I don’t think you need another tutorial to reinstall a sim card in your device. Just remove the sim tray from the device and restart the device and then reinsert it to the device.

  • Activate the flight mode.
  • Push Sim eject tool into the circular opening on the SIM card tray to remove it.
  • Power off the device.
  • Remove the Sim card from the Sim tray then place it back in.
  • Push the tray back into the slot.
  • Boot the device.

Once you’ve removed the SIM card from the device, wait for a few moments before re-inserting it. This has the effect of refreshing the system without the old cellular settings. Once the SIM card is re-inserted and the phone restarted, your network’s configuration should be added automatically.

If you have another phone that can work with your network, you can also try to insert the SIM card to it. This will help you check if there’s an issue with the SIM card itself. If the problem returns when you use the SIM card in the second device, you either have an issue with the SIM or with the network. Try getting a new SIM card to see if it’s the SIM or the network.

Use another SIM

If nothing changes after reseating the SIM, your next move is to see if the issue is caused by a defective SIM card. There are two ways to do this. One is by getting a new SIM card from your carrier. The other way is to borrow a known working SIM card from someone and see if your S20 detects the card.

Reset Network Settings

  • Open the app drawer and then tap Settings.
  • Then go to System
  • And then Reset Options.
  • Now, tap on Reset Wi-Fi, mobile & Bluetooth.
  • Tap RESET SETTINGS.
  • Enter your PIN or Password, then tap Next.
  • Tap RESET SETTINGS again to confirm.

Troubleshoot apps in Safe Mode

In case you don’t know what is safe mode, in safe mode, the system temporarily disable all third-party applications you installed on your device. By doing this we can figure out which app is occurring the problem. Follow the below step to turn Safe Mode on:

  • Turn OFF the OnePlus device.
  • Press and hold the Power button.
  • On the screen, press and hold Power off.
  • Tap Ok to reboot into Safe mode.

After figuring out the apps which are creating the problem, follow the below steps to uninstall it(if required):

Clear Cache from Recovery Mode

In case you don’t know what is recovery, the first thing the bootloader rings up is the recovery. Recovery Mode refers to a special bootable partition, which contains a recovery application installed in it. And you can fix some problems with your phone. Follow the steps to clear cache from recovery mode:

  • Switch off your OnePlus device.
  • Now press and hold the Power and Volume Down buttons simultaneously until you see the recovery mode options on your device.
  • Once you see the recovery options, you can let go of the two buttons.

  • Use the Volume button to go to Wipe Cache Partition then press the Power button to confirm the selection.
  • Wait until your device wipes out all cache or temporary data from the system partition.
  • Press the Power button again to reboot the device.

This clears all the temporary data from the device. And then it works like new.
