Solutions to Samsung Galaxy Note10 mobile data problems after an Android 10 update

Mobile data problems can have many possible causes so you’ll have to perform a number of troubleshooting steps to isolate its cause. This guide will show you what you must do to find out the best solution that will work on your case.

Find out if there’s network service in your area

Before you do any troubleshooting on your Note10, it’s important for you to know if the issue is network-related or not. You’ll need to confirm if the issue is bad or weak signal strength by checking the signal bar indicators on the status bar.

In general, if the signal bars keep disappearing or if the bars are only playing between 0 and 2 bars, that can mean that you’re in a poorly covered area. If you are in a location with poor signal coverage, signal bars would show as weak or constantly fluctuating. If there are only 2 less bars, you can’t expect mobile data to be fast.

Try to move to another area and see if that will improve the signal bars before testing mobile data again. If you’re inside a building, go to a more open area, taking cue from the signal bars on your phone.

Weather conditions can also affect how network services work. You can expect poor network or low signal bars when there’s a storm, rain, or heavy or windy conditions. If your area has already poor network coverage and the weather is bad, mobile data on your Galaxy Note10 may not work properly.

Are other network services affected?

If texting, and voice calling are also not working at this time, you can assume that it’s either a poor signal situation or there’s an on-going network outage. Try moving to a more open area with known high quality network coverage, such as areas in city centers and see if your data problems disappear.

Verify your mobile data subscription is active

In most cases, mobile data is not free for subscribers so a sudden stop for this service can mean that you will have to settle your bills first.

If you think that this factor can play a role in your situation, make sure to get advice from your carrier on what to do.

In most instances, paying the outstanding service will automatically restore the service.

Refresh the system by rebooting it

Doing a simple solution such as rebooting can sometimes fix network bugs as well. If you haven’t tried it yet, be sure to restart your Note10.

Try restarting it normally first by pressing the Power button to access the boot menu. Then, select Restart option and see if that works.

Another way to restart the device is by pressing and holding the Volume Down button and the Bixby/Power key at the same time for 10 seconds or until the device’s screen turns on. This simulates the effect of having disconnected the battery from the device. If this works, this may unlock the device.

If doing the regular restart won’t help, then try this:

  1. Press and hold the Volume Down button first and don’t release it.
  2. While holding it down, press and hold the Power key.
  3. Keep both keys held down for 10 seconds or more.

The second restart procedure tries to simulate the effects of removing the battery pack. On older devices, disconnecting the battery is often an effective way in fixing unresponsive devices. If nothing changed though, proceed to the next suggestions.

Rebooting your device regularly at least once every week can be beneficial. If you tend to forget things, we suggest that you configure your phone to reboot on its own. You can schedule it to do this task by doing these steps:

  1. Open Settings app.
  2. Tap Device Care.
  3. Tap the 3-dot at the top.
  4. Select Auto restart.

Clear current network configuration

One of the basic troubleshooting steps in this situation is to clear the current network configuration. This is because sometimes, system-wide changes may affect network settings such as cellular configuration. Fortunately, the solution is easy when this occurs. One simply needs to reset the network settings of the device to everything network-related are returned to their last known working configuration. If you haven’t tried this one yet, be sure to do so. Here’s how:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset network settings.
  5. Tap Reset settings to confirm.

Troubleshoot the SIM card (SIMtoolkit or SimMobilityKit)

If your data problems remain on your Galaxy Note10 after an Android 10 update and won’t go away, you can also check the SIM card.

After doing some software troubleshooting, it may sometimes boil down to a poor SIM card condition or unknown SIM hardware malfunction.

There are three things that you want to do about the SIM card and its corresponding app:

  • Physically check the card
  • Force quit the SIM card app (SIMtoolkit or SimMobilityKit)
  • Clear SIM card app cache
  • Return SIM card app to defaults

Physically check the SIM

One of the basic things that you can do when dealing with network problems such as mobile data not working issue is to ensure that the SIM card is in good condition. This is important especially if you tend to remove and insert SIM card back and forth.

When removing a SIM card, you want to make sure that your Note10 is off to avoid corrupting some data. Once you’ve taken the SIM out, be sure that you wipe the copper contacts with clean, soft cloth to remove dirt that might cause poor connection.

You also want to inspect if the card has obvious signs of damage. Although the SIM is pretty tough and can withstand even long water exposure, it can still break. If you notice any sign of physical damage, get a new one from your carrier.

Force quit the SIM card app (SIMtoolkit or SimMobilityKit)

Before you start troubleshooting the SIM app, which can be SIMtoolkit, SimMobilityKit, or any other similar names, make sure that you insert the physical card properly.

Once you’ve done that, you can then begin to troubleshoot the app. You can begin by rebooting it. This is usually effective in fixing specific types of minor app bugs.

To force quit any app:

Method 1: Close an app using Recent Apps key

  1. On your screen, tap the Recent Apps soft key (the one with three vertical lines on the left of the Home button).
  2. Once the Recent Apps screen is shown, swipe left or right to look for the app. It should be here if you managed to run it previously.
  3. Then, swipe up on the app to close it. This should force close it. If it’s not there, simply tap the Close All app to also restart all apps.

Method 2: Close an app using App Info menu

Another way to force close an app is by going within the app’s settings itself. It’s a longer way compared to the first method above but it’s equally effective. You want to use this method if you plan on doing other troubleshooting for the said app like clearing its cache or data. Here’s how it’s done:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the app.
  6. Tap Force Stop at the bottom.

Clear SIM card app cache

If force closing the SIM app won’t help, it’s a good idea to continue troubleshooting the app by wiping its cache. Apps keep a certain set of temporary files in order to do tasks more efficiently. Sometimes, an app cache may become corrupted causing the app to misbehave.

To clear an app cache:
  1. Go to the Home screen.
  2. Tap Apps icon.
  3. Open Settings app.
  4. Tap Apps.
  5. If you’re looking for a system or default app, tap on More settings at the upper right (three-dot icon).
  6. Select Show system apps.
  7. Find and tap the appropriate app.
  8. Tap Storage.
  9. Tap Clear Cache button at the bottom.

Return SIM card app to defaults

If the first two SIM app troubleshooting has not helped so far, we recommend that you clear the data of the app. This has the effect of a mini factory reset for the app as all its settings are returned to the original, factory state. This may sometimes work if the app in question has a problem with the new app update.

To clear an app’s data:

  1. Go to the Home screen.
  2. Tap Apps icon.
  3. Open Settings app.
  4. Tap Apps.
  5. If you’re looking for a system or default app, tap on More settings at the upper right (three-dot icon).
  6. Select Show system apps.
  7. Find and tap the appropriate app.
  8. Tap Storage.
  9. Tap Clear Data button.

Keep apps updated

As a general rule, be sure to allow Play Store to auto-update apps. This is the default setting but if you change it before, make sure that you manually check for app updates from time to time.

To check for Play Store app updates on your Galaxy Note10:

  1. Open Play Store app.
  2. Tap More settings icon at the upper left (three-horizontal lines).
  3. Tap Settings.
  4. Tap download preference.
  5. Select Over wifi only (select Over any network if you don’t have wifi).
  6. Tap Done.
  7. Tap Auto-update apps.
  8. Tap Over wifi only (select Over any network if you don’t have wifi).
  9. Tap Done.

Turn Roaming off

If you are not in your home country and mobile data not working on your Galaxy Note10, Roaming may be to blame. You usually need to enable Roaming feature in your account first before leaving your home country so you can continue using network services normally abroad. Exact procedures on how Roaming is activated varies by carrier so be sure to contact your network operator for accurate information.

On the other hand, if you just returned from a trip abroad, the reason for your problem right now may be that Roaming is not turned off. To do that, follow these steps:

  1. Open Settings app.
  2. Tap Connections.
  3. Tap Mobile networks.
  4. Move slider of Data roaming to the left to turn it OFF.

Change network mode

If you still have data problems on your Note10 after Android 10 update, try changing a device’s network mode. If you’ve been using 4G LTE for your data needs, try switching to, say, 3G, and see if that will make a difference. If you haven’t tried doing this as of this point, here are the steps to follow:

  1. Open Settings app.
  2. Tap Connections.
  3. Tap Mobile networks.
  4. Tap Network mode and select 3G or 2G.
  5. Restart device and repeat steps 1-3.
  6. Tap 4G or LTE or auto-connect to return to the original configuration.

Manually disconnect from your home network

Another possible solution that you can do in this situation is to force your phone to disconnect from your carrier’s network. This can sometimes clear up network bugs.

Here’s how to do it:

  1. Open Settings app.
  2. Tap Connections.
  3. Tap Mobile networks.
  4. Tap Network operators.
  5. Tap Select manually.
  6. Wait for your device to search for networks.
  7. Once it’s done searching, select another network to connect to. For example, if you’re on T-Mobile, pick AT&T or any other network.
  8. Your phone will be forced to return with an error because it won’t be able to register successfully.
  9. Afterwards, select your own network again and see if your device will now be able to re-register.

Run device on Safe Mode

Safe Mode is an important utility tool for technicians and average users alike to diagnose bad third party app in a system. If you continue to have data problems on your Note10 that’s running the latest Android 10 update, you must consider checking if a bad third party app is to blame.

To restart your Samsung Galaxy Note10 to safe mode:

  1. With your device turned on, press and hold the Power button until the Power off menu appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” should appear in the lower-left of the home screen.
  6. Check for the problem.

Safe Mode may be a useful trick in checking for a problem but it won’t pinpoint the exact app. In order to identify which of your apps may be behind the problem, you’ll have to do a process of elimination. Here’s what you need to do exactly:

  1. Boot Galaxy Note10 to safe mode.
  2. Check for the problem.
  3. If the issue returns or once you’ve confirmed that a third party app is to blame, you can start uninstalling apps one by one. You’ll need to do spend some time doing this if you have plenty of apps installed. We suggest that you begin with the most recent ones you added.
  4. It’s important that you only uninstall a single app at a time. After removing an app, restart the phone to normal mode and check for the problem again.
  5. If your Galaxy Note10 is still problematic, repeat steps 1-4 until the rogue app has been identified.

Wipe the phone and return software to defaults (Factory reset)

This is a drastic solution that can cause a lot of hassle for a user if he or she is not fully into it. Factory reset will erase your personal data such as documents, images, videos, contacts, etc., so be sure that you back them up ahead of time.

Factory reset can be effective though if the main cause of the problem is software-related. If performing all our suggestions above has come to this point and your Note10 still has data problems when Android 10 update was installed, don’t hesitate to wipe your device.

Below are the two ways to factory reset your Note10:

Method 1: How to hard reset on Samsung Galaxy Note10 via Settings Menu

This is the easiest way to wipe your Galaxy Note10. all you have to do is to go under Settings menu and follow the steps below. We recommend this method if you have no trouble going under Settings.

  1. Create a backup of your personal data and remove your Google account.
  2. Open Settings app.
  3. Scroll to and tap General management.
  4. Tap Reset.
  5. Select Factory data reset from the given options.
  6. Read the information then tap Reset to continue.
  7. Tap Delete All to confirm action.

Method 2: How to hard reset on Samsung Galaxy Note10 using hardware buttons

If your case is that the phone is not booting up, or it boots but Settings menu is inaccessible, this method can be helpful. First, you need to boot the device to Recovery Mode. Once you successfully access Recovery, that’s the time that you begin proper master reset procedure. It may take some tries for you before you can access Recovery so be patient and simply try again.

  1. If possible, create a backup of your personal data ahead of time. If your problem prevents you from doing that, then simply skip this step.
  2. Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
  3. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  4. Press and hold the Volume Up button and the Bixby button at the same time.
  5. While still holding the Volume Up and Bixby keys, press and hold the Power button.
  6. The Recovery screen menu will now appear. When you see this, release the buttons.
