Fix Emergency Calls Only Bug on OnePlus 8 Pro

Verify signal strength

In a lot of network issues, poor or weak signal is to blame. If your OnePlus 8 Pro is showing No Service all the time recently, be sure to check how the signal bars are showing on your device. Anything lower than 3 bars is not good and can indicate a network issue.

If you are inside a building, try to go out and see if No Service goes away. If you are traveling by car, it’s possible that you may be transiting a dead spot. What you want to do is to move a known well-covered area. If No service remains, there may be an issue with your OnePlus 8 Pro. Continue troubleshooting it by following the steps below.

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.
