How to fix Huawei P30 mobile network not available | not detecting network

Fixing Huawei P30 mobile network not available is easy. It’s usually fixable on an user’s level. Learn what you can do to fix this problem below.

Huawei P30 mobile network not available fix #1: Check signal

Mobile network not available error on Huawei P30 may mean that the problem is signal-related. This occurs if the device is in a poorly covered area, or when the signal can’t reach it consistently. Try checking if the signal fluctuates between excellent (maximum signal bars to poor). If this is true, then the problem is on quality of service rather than something within the device. To fix the error, simply relocate to an area with better signal. If you’re inside a building when mobile network not available error shows up, moving in a more open space should fix the issue.

Huawei P30 mobile network not available fix #2: Check voice calling

Texting and voice calling often works in the same network mode. If you are having an issue with one, the other will most likely not work as well. If both, texting and voice calling, are not working when mobile network not available error occurs, there may be a network or device issue at hand. Continue with the troubleshooting steps below. 

Huawei P30 mobile network not available fix #3: Reseat SIM card

One of the basic factors that you also need to check at this point is the SIM card. You can do so by turning off your phone and removing the SIM card temporarily. After that, wait for a few seconds before inserting the SIM card again. If it helps, make sure to also clean the SIM card by wiping its copper contacts before you re-insert it. SIM cards rarely go bad but total failure is not unheard of. In most cases, an account issue can be the reason why a SIM card may not work properly. At other times, it can be physical damage or dirt that sticks on the copper contacts. Either way, the best way to check if the SIM card works fine is by getting a new one. If possible, try visiting your local carrier store and see if you can get a SIM card replacement. Make sure to ask for directions how to keep your number to avoid causing account problems. If getting a new SIM card is a bit too much, try to insert your current SIM to another compatible phone and see if it works. If it does, proceed to the next troubleshooting step.

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.

Huawei P30 mobile network not available fix #7: Check for rogue apps

If the Huawei P30 mobile network not available error happened after you installed a new app, that app may be to blame. Uninstall it and see if it fixes the issue.

If you can’t remember which app you installed, or if you suspect that a bad app is in the system, try to return the device to safe mode. 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.

Huawei P30 mobile network not available fix #10: Return software to defaults

Though not necessary at all times, factory reset may help in this situation. If the cause of the problem is an unknown software bug, wiping the device with factory reset might help.

There are two methods to perform a factory reset on your Huawei P30. You want to do the first one first if there’s no problem going under Settings menu.

Method 1: Hard reset on Huawei P30 via Settings

Wiping your phone with factory reset will automatically erase information from your device’s internal storage. The software environment on your device is basically returned to its original form, just like when it left the factory. This means that everything you added to the device like files, photos, videos, and apps will all be deleted. If you don’t want to lose irreplaceable data, make sure to create a backup ahead of time.

There can be many different reasons why a user may want to factory reset a device. If your situation calls for a Hard reset on Huawei P30  and you are able to access your device’s settings menu, then this first method is for you. It’s easier to do compared to the second one below so this is a go-to method for you.

To perform a Hard reset on Huawei P30 via Settings:

  1. Create a backup of your personal data.
  2. Turn on the device.
  3. Tap Settings.
  4. Tap System.
  5. Choose Reset.
  6. Tap Reset all settings.
  7. Tap Reset all settings.
  8. Confirm the action by tapping on Reset all settings.
  9. Wait for factory reset to finish.

Method 2: Hard reset on Huawei P30 via Recovery Mode

This method is useful in one particular situation: when Settings menu is not accessible. There may be a variety of reasons why Settings menu may become unreachable. In some cases, the device may have simply frozen or unresponsive. At other times, it can be due to a problem that you are currently trying to troubleshoot. In any case, you must do Hard reset on Huawei P30 via Recovery Mode when the situation forces you to. We still recommend that you use the first method as your primary option for convenience reasons. Effects-wise, the two methods don’t have any difference at all. The device will be completely sanitized and all user data deleted after doing any of them.

To perform a Hard reset on Huawei P30 via Recovery Mode:

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