OnePlus 12 and 12R No Signal or Network Issue, How to Fix?

Any network or signal issues are common, mainly due to software issues on the device. So, let’s see how you can diagnose the problem and try to solve the network issue using the various troubleshooting methods mentioned below.

Fix 1: Verify Network Strength

The strength of your network or signal is determined by your carrier and the availability of nearby cell towers. If you are in a metropolis, your network may not be detected due to distance from cell towers. If you move farther from the nearest cell tower, the signal strength will decrease owing to a scarcity of cell towers.

You can verify the strength of your network on your device, or on another device that uses the same carrier. If the network strength is weaker on your device, then there might be an issue with your device. However, if the issue persists on the other device as well, then it’s possible that the carrier is experiencing outages in the area or doesn’t have enough cell towers to provide better signal strength.

Fix 2: Enable & Disable Airplane Mode

If you are experiencing network or signal issues on your OnePlus 12 or 12R device, one possible solution is to enable and disable Airplane mode. This function temporarily cuts off the cellular network and can act as a bug fix for network problems. To try this solution, simply turn on Airplane mode and wait a few seconds before turning it off again to restore the network on your device. If this solution does not work, you may need to try other methods to fix the issue.

Fix 3: Restart Your Device

If you’re experiencing network issues on your OnePlus 12 or 12R device, restarting it might help. Sometimes, bugs and glitches can cause temporary signal problems, and restarting your device can fix minor issues. To restart your OnePlus device, follow these steps:

  1. Press and hold the power button for a few seconds until the Restart/Reboot option will pop-up on the screen.
  2. Tap on the Restart/Reboot option.
  3. Your device will automatically turn off and back on after a few minutes.
  4. Try to check if the network strength on your device is resolved.

Fix 4: Verify the Preferred Network Type

The carrier provides a range of network services including 2G, 3G, 4G, and 5G. Every phone is equipped with a SIM card slot that supports different network generations. However, if you’ve selected the wrong preferred network type on your phone, you may not be able to see the network or signal strength. The preferred network modes help your phone to access cellular connectivity in 4G and 5G networks.

In case there are no 4G or 5G networks available, you can switch to 2G and eG networks as a backup. If you’ve chosen the second type, try to access the 4G network. It’s crucial to choose the right preferred network type on your device. If you’re unsure how to select the network mode, follow these steps:

  1. Open the Settings app on your device.
  2. Go to Connections > Mobile Networks.
  3. Tap on “Network Mode” and choose “5G/4G/3G/2G (auto connect).”
  4. Now try to check if the network has been restored or not.

Fix 5: Change the Carrier

If you are experiencing weak signal strength on your OnePlus device, it could be due to an issue with your network provider. In such cases, it is recommended that you switch to a different carrier. You can easily port your existing number to the new carrier and take advantage of their exciting offers.

Fix 6: Wipe Cache Partition

Cache files can speed up the retrieval of applications and websites. However, these files can easily become corrupted and cause issues such as freezing and glitches on your device. If you are experiencing network or signal issues on your OnePlus device, you can perform a wipe cache partition to fix the problem. Here are the steps to do it:

  1. Turn off your OnePlus device completely.
  2. Press and hold the Volume Up + Power Key button simultaneously for a few seconds until the Phone doesn’t vibrate.
  3. Go to the Wipe cache partition by using the Volume up key and select it using the power key button.
  4. Now, you have to confirm it by selecting the Yes option.
  5. Finally, select “Reboot System Now” from the given option, and it’s done.

Fix 7: Reset Network Settings


Reset network settings will erase the temporary networks on your OnePlus device and help you solve network or signal issues on the phone. Here’s what you can do when there’s an issue with the network on your device:

  1. Go to Settings > Additional Settings.
  2. Scroll down and select Backup & Reset > Reset Phone.
  3. Finally, tap on Reset Network Settings and confirm it to proceed.

Fix 8: Try Using Roaming Services

It’s also possible that the roaming service may help you to get back to the network on your OnePlus 12 and 12R device. You might have to enable roaming service if you’re out of the network circle. Go to Settings > Connections and search for “Roaming Services.” Turn it ON, and this should restore the roaming-related network issues.

Fix 9: Re-insert the SIM Card

A lack of signal or network issue on your OnePlus 12/12R device might be caused by a corrupted or improperly inserted SIM Card. To resolve the issue, try re-inserting your device’s SIM Card. Remove the SIM Card from your device, then properly re-insert it and check if the issue is resolved.

Fix 10: Check Your SIM Card for Any Damaged

If you have reinserted the SIM card and are still experiencing network or signal issues on your OnePlus device, it’s recommended to check your SIM card for any hardware damage. If the SIM card is cracked or damaged, it won’t be recognized by your device and no network will be found. In such cases, you will need to replace the SIM card by porting it with the same number.

Fix 11: Contact OnePlus Support Team

If you have followed the solutions mentioned above and continue to experience network issues with your OnePlus 12 and 12R device, it is recommended that you contact the OnePlus customer support team for assistance. There may be an issue with the phone itself, so reaching out to OnePlus support is the best course of action.
