How to fix mobile data not working on Huawei P30 | troubleshoot Huawei P30 network issue

Fixing mobile data not working issue is usually easy. In a lot of cases, the solution is available at an end user’s level so we hope that this is also the case in your particular situation. Follow the suggestions below if your Huawei P30 has a mobile data trouble.

Mobile data not working fix #1: Enable mobile data

Is mobile data not working on your Huawei P30? Check and make sure that you tap on the Mobile data switch. This may sound like a no-brainer but a lot of folks forget to do it. Instead of panicking what to do right away, ensure that you do this one simple step.

Mobile data not working fix #2: Check if network is up

The next basic thing to do in this situation is to verify whether or not there’s any network trouble. It’s fairly easy to do. Simply take a look at the status bar and see if there are signs of network failure. If the signal bars and network mode indicators (2G, 3G, 4G/LTE) are missing, that can mean that there may be an outage, or there’s a problem with your network. If you are not sure, contact your network operator right away to get accurate first hand information. You don’t want to waste your time troubleshooting your Huawei device when the reason for the problem is outside of it.

Mobile data not working fix #3: Be mindful of signal strength

Even if the network appears to be working and its services are present, that doesn’t necessarily mean that mobile data works as expected. Although there’s a lot of factors that might affect mobile data connectivity on your phone, one of the best indicators of its performance that’s available for you is the number of signal bars on the status bar. In general, mobile data connection should work fast if you have excellent coverage, which means the signal bars for 4G LTE are full. If there’s only a couple of signal bars on your device, that can be the reason why mobile data is slow or not working at all. If signal bars appears to come and go and mobile data tends to also disconnect or stop working when the indicators are out, that’s a clear sign of a possible network issue. You can either wait it out or transfer to an area with a more stable network coverage. If you did not have any mobile data problems in the same area before, you can report the problem to your carrier so they can do something about it.

Mobile data not working fix #4: Check account/billing status

In case you’re not aware, mobile data is usually not included in regular call and text plans. If your subscription plan does not include mobile data, you must talk to your carrier to add this extra service to your account. It has separate pricing depending on how much data you want every month. Get information from your carrier if you plan on using mobile data on top of your current basic plan.

If you are already using mobile data before but the service disconnects or stops working all of a sudden, it can be due to an issue with your account. Before you perform any device troubleshooting, you want to make sure that your account is in order and that mobile data service is activated.

Mobile data not working fix #5: Insert SIM to another phone

If you are positive that mobile data should be working and there are no account issues at all, the next troubleshooting step that you can do is to insert your SIM card to another compatible phone and check out mobile data on it. By compatible phone we mean a device that can work with the current network you’re using. For example, if you’re on AT&T, make sure that the second device can run on AT&T network. If mobile data still won’t work on the second device, that’s either due to a network problem or an account issue. However, if mobile data works normally on the other phone, that means that your Huawei P30 is to blame. There may be a problem with its settings, app, or software. Continue your troubleshooting by following our suggestions below.

Mobile data not working fix #6: Reset network settings

A Huawei device can sometimes encounter network troubles if network settings are incorrect. This doesn’t mean that you personally made some incorrect changes. Sometimes, an app or update can lead to changes that’s not optimal for other apps or for the Operating System. Bad network configuration may occur for a lot of reasons. What you can do now is to ensure that you return all network settings to their defaults so the system can use them moving forward. To reset all network settings, follow these steps:

  1. Open the Settings app.
  2. Go to Advanced settings.
  3. Scroll to and tap Backup & reset.
  4. Select Network Settings Reset from the given options.
  5. If prompted, read the warning message and then tap Network Settings Reset twice to confirm.

Allow your device to finish resetting network settings and restore the default values. When it’s done resetting network settings, reboot your phone then reconnect to your Wi-Fi network.

Mobile data not working fix #7: Perform a soft reset

At this point, the next best thing that you can do is to refresh the system. Restarting a device can sometimes do wonders. Make sure that you forced restart your phone if none of the suggestions has worked so far. Try to do a forced reboot by pressing and holding the Power key for 10 to 15 seconds. If your phone works, it should reboot and you should feel a vibration and see the Huawei logo. In case you do not feel the vibration and the screen is still blank, then simply press and hold the Power Key for more time until you see the device restart itself.

If nothing changes after attempting to reboot the device a few times, you can abandon this troubleshooting and proceed to the next ones below.

Mobile data not working fix #8: Install updates

Some network problems can only be fixed by changing software codes. If your device is still showing No Signal issue at this point, make sure that you install whatever available software update there is at the moment. If there’s no any available update at all, then simply ignore this suggestion. Some network problems can only be fixed by changing software codes. If your device is still showing No Signal issue at this point, make sure that you install whatever available software update there is at the moment. If there’s no any available update at all, then simply ignore this suggestion. Here’s how to manually check for software updates on the P30:

  1. Go to Settings.
  2. Tap System.
  3. Select System Update.
  4. Tap the option to Check for Updates.

To check for any pending app updates you’ve downloaded through the Google Play Store app, launch Play Store then navigate to the Updates section. You will then see a list of apps with pending updates. Just tap on Update to install individual app updates or tap Update All to update apps simultaneously.

Don’t forget to reboot/soft reset your P30 after installing updates to ensure all new software changes are properly implemented and to prevent any app from going rogue.

Mobile data not working fix #9: Wipe cache partition

Android devices like your Huawei P30 uses a special cache called system cache to open and load apps faster. The system cache includes items like website links, images, videos, ads, among others. It’s stored in a portion of the internal storage called cache partition. Sometimes, the system cache may get outdated or corrupted causing performance problems or bugs. To ensure that you phone runs efficiently and the cache in top shape, you want to regularly clear the cache partition (about once every few months). When dealing with any app issue, this can also be one of the troubleshooting steps. Here’s how to do it:

  1. With your phone turned off, press and hold both the Volume Up and Power buttons simultaneously for at least 10 seconds.
  2. Let go of the buttons when the Honor logo appears.
  3. Shortly after seeing the logo, the EMUI screen shows up with the recovery mode options.
  4. Press the Volume Down button to scroll to and highlight Wipe cache partition option.
  5. Then press the Power button to confirm selection.
  6. Use the Volume buttons to scroll to and highlight the next options and Power button to confirm selection.

Mobile data not working fix #10: Check for bad apps

Sometimes, a third party app may cause problems or interfere with the Operating System. Having network troubles due to a bad app is not unheard of in Huawei devices. Restart the phone to safe mode and see if that’s the case. In safe mode, no third party app should be able to run. So, if wifi works normally on safe mode, you can bet a bad third party app is to blame. Here’s how to boot it to safe mode:

  1. Power off the device.
  2. Power it back on.
  3. Once you see the Huawei animation on the screen press and hold Volume Down button.
  4. You can see safe mode at the bottom left corner once the device finishes booting.
  5. Now that the device has started on safe mode, charge it and see if there’s a difference.

Don’t forget: safe mode blocks third party apps but it won’t tell you which of them is the real cause. If you think that there’s a rogue third party app in the system, you must identify it. Here’s what you need to do exactly:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Huawei P30 is still problematic, repeat steps 1-4.

Mobile data not working fix #11: Factory reset

If there’s no change at all and mobile data is still not working at this time, the final drastic solution that you should try is factory reset. This will return all software settings to their defaults, delete all apps you downloaded and personal data, and basically cleans up the phone. If the reason for the problem is unknown software bug, factory reset will likely be of help. Before you perform this troubleshooting step, be sure to create a backup of your personal data to avoid losing them.

To factory reset your Huawei P30:

  1. Turn off the mobile by pressing the Power key for a few moments.
  2. Press and hold Volume Up and Power buttons for a couple of seconds.
  3. When Recovery Mode appears let go of all keys​​​​​​.
  4. Now choose “wipe data/factory reset”. Use Volume buttons to navigate and the Power key to accept it.
  5. Confirm the operation by typing in “yes” and select “wipe data/factory reset”.
  6. When you see the Google Verification info confirm the operation by selecting “wipe data/factory reset”.
  7. Finally choose “reboot system now” by using the Power key.

Mobile data not working fix #12: Get help from carrier

It’s rare to see mobile data issues not resolved by a factory reset but if your case continues even after wiping the phone, you can bet a bad hardware or a coding glitch is to blame. It’s also possible that there may be an issue with your account that the previous representative was not able to detect. Try to get hold of your carrier’s technical team again so they can do further troubleshooting. If they’ll say that your account is perfect (this can be validated by inserting your SIM to another phone and checking mobile data using it), then your device may be defective. In this situation, you may want to get help from Huawei itself.
