This usually happens when there’s an issue with the phone’s signal receiver, which may stop working due to a wide variety of reasons.

Of course, as soon as signal bars disappear, the first instinct is to visit the service center and get the device repaired. But, before you spend hundreds of dollars on repairs, it would be better to try a few troubleshooting methods to fix the “no signal bars on Android” issue on your own. In this guide, we have penned down 12 different ways to troubleshoot your device when it doesn’t have any signal bars.

Part 1: 5 Quick Fixes to Solve Phone Has No Signal Bars

We’ll start by implementing simple solutions first because in many situations, the error is temporarily caused by a minor bug. Here are five of the quick fixes to resolve no signal bars on your Android device.

Fix 1. Enable and Disable Airplane Mode

First and foremost, swipe down on the home screen to bring down the notification tray and then, tap the “Airplane Mode” icon to put your device in airplane mode. Then, wait for a few seconds and again click the same icon to disable airplane mode. Enabling and disabling the airplane mode will quickly restore the network settings on your phone, which might resolve the “my phone has no signal bars anywhere” problem.

Fix 2. Display Status Bar Network Speed

If you have accidentally turned off the network speed feature on your Android device, it might be the reason why you’re not seeing any signal bars too. In this situation, simply restore the network speed status to resolve the problem.

To do this, go to “Settings>Network and Internet” and then, tap the “Status bar network speed display on” option to display network speed on the notification bar.

Fix 3: Reboot Your Phone

Like many technical errors, you can also resolve no signal on a cell phone by simply rebooting the device. When you restart a smartphone, all the background processes shut down immediately. So, if a third-party application or system process is causing the problem, you won’t see it anymore.

Fix 4. Check Your Sim Card

If you are still not seeing any signal bars, you may want to diagnose the SIM card as well. Check if the SIM card is properly placed in the SIM tray. You can also insert the SIM card in another phone and check for signal bars there. In case a different smartphone doesn’t display signal bars either, contact your network service provider as there’s an issue with the SIM card itself.

Fix 5. Select Carrier by Yourself

Manually selecting the network carrier when your Android/iPhone device fails to do this automatically is another way to resolve the phone has no signal bars error.

To do this, go to “Settings>Network and Connectivity”. Then, click the “Network Operators” option and let the device automatically scan for local network carriers. Finally, select the desired network carrier. This will restore the signal bars on your device instantly.

Part 2: 7 Deep Fixes to Solve Phone Has No Signal Bars

In case performing these simple solutions doesn’t resolve the problem, the next step would be to implement advanced troubleshooting methods to get the job done. These methods include.

Fix 1. Perform Ping Test

Performing Ping Test is a way to check if cellular radio is working on your device or not and enable the radio if it’s been disabled accidentally.

  • Step 1. Open the “Dialer” app on your phone and call “*#*#4636#*#*” to enter service mode.

    enter service mode to perform ping test

  • Step 2. Select the “Device Information” option and then, tap “Run Ping Test”.
  • Step 3. The Radio Data status will appear at the bottom of the screen. In case it’s off, turn the cellular radio back on to bring back the disappeared signal bars.

Fix 2. Check APK and ROM

If your phone has no signal bars yet, it might be due to the third-party applications or your custom ROM. It’s worth understanding that custom ROMs aren’t as stable as the official ROM. They are loaded with bugs and can make your device run into several errors. So, if you’ve also been experimenting with custom ROMs for a while, you may want to stop and flash the original ROM to resolve the problem by restarting the phone into the boot menu and then doing a factory reset.

Fix 3. Nulled IMEI

Sometimes different third-party applications can nullify an Android phone’s IMEI number, which is a common cause behind the phone having no signal bars problem. If that’s the case, you’ll have to manually restore the IMEI number to resolve the problem.

  • Step 1. Dial “ *#06#” from your phone and check if it returns your phone’s IMEI number.
  • Step 2. In case the above call returns “Null” message instead, go ahead and dial “*#*#197328640#*#*”. This will make your device enter the command mode.
  • Step 3. A menu will appear on your screen. Here you have to turn off “Field Test Mode” to restore the IMEI number.

Once the IMEI number gets restored, you’ll see the signal bars on the screen.

Fix 4. Switch to Roaming

If you are visiting a different state, you may want to turn on data roaming to receive network signals properly. Again, go to “Settings” and click on “Network and Connectivity”. Then, click on “Mobile Network” and toggle the switch next to the “Data Roaming” option to turn it on.

Fix 5. Update to the Latest Software

Running an outdated version of mobile OS can also trigger unexpected errors such as “phone recognizes SIM but no signal” error. That’s why it’s always advised to keep your smartphone updated to the latest available OS version. Go to “Settings” and click on “Software Updates”. In case there are any pending software updates, make sure to install them to resolve the error.

Fix 6. Perform Factory Settings

Another effective way to resolve a phone that has no signal bars is to simply perform a factory restore. This will restore all the system settings like a brand new device.

  • Step 1. Open the “Settings” app on your phone and click “Backup and Reset”.
  • Step 2. Then, tap the “Factory Data Reset” option and follow the on-screen instructions to reset your device to the factory settings.
