How to fix Galaxy Note10+ mobile data not working | mobile data won’t connect

There are a lot of factors that can result to why your Galaxy Note10+ mobile data is not working. In this post, we’ll show you the things that you must check as well as the specific troubleshooting steps to do to fix this issue.

Before you proceed, make sure that you check these two basic things:

  • Mobile data is ON
  • Mobile data subscription is active

If both items are positively determined to be good, then proceed to the rest of the troubleshooting steps below.

Galaxy Note10+ mobile data not working fix #1: Confirm signal strength is good

If you’ve confirmed that the basic things are in place, the next good thing that you can do is to ensure that the signal on your Galaxy Note10+ is excellent. Many users often forgot this step. The signal bars icon on your phone is a good indicator whether or not network services such as calls, texts, and mobile data work normally. 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.

Galaxy Note10+ mobile data not working fix #2: Check voice calling or texting

Most of the time, mobile data issues are caused by a fault in the network- or server-side and not on the device. If mobile data is not working, make sure to check if voice calling or texting on your Galaxy Note10+ are having issues as well. If they do, you can assume that there might be a problem coming your carrier. What you need to do next is to continue troubleshooting a few more steps like doing a network settings reset and device reboot. If these things won’t help, skip the rest of the suggestions below and get help from your network operator.

Galaxy Note10+ mobile data not working fix #3: Reset network settings

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.

Galaxy Note10+ mobile data not working fix #4: Perform forced reboot

Doing simple solutions 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.

Galaxy Note10+ mobile data not working fix #5: Keep software and apps updated

Some network problems may require fixes to a device’s modem firmware, network settings, or software. In this situation, solutions are often implemented via over-the-air updates. Make sure to install any available update. If you blocked your device from automatically downloading software update (some carrier-branded devices don’t have this option), you can manually check under Settings > Software update.

In the same vein, you want to keep your apps up to date as well. Some poorly coded apps may require their most recent update in order to start working again. As a general rule, be sure to allow Play Store to auto-update apps. This is the default setting but if change it, 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.

Galaxy Note10+ mobile data not working fix #6: 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.

Galaxy Note10+ mobile data not working fix #7: Change network mode

Sometimes, changing a device’s network mode from, say, 4G LTE to 3G can get rid of network problems. 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.

Galaxy Note10+ mobile data not working fix #8: Disconnect from network

If your Galaxy Note10+ mobile data is still not working at this time, consider temporarily disconnecting from your network operator. 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 and fix the EMERGENCY CALLS ONLY bug.

Galaxy Note10+ mobile data not working fix #9: Reseat SIM

In some network-related cases, temporarily disconnecting your Galaxy Note10+ SIM card may fix problems. If you haven’t tried this yet, follow these steps to safely proceed:

  1. Turn off your Galaxy Note10+. This is important. Inserting a SIM while the device is on may result to corrupted data.
  2. With your phone’s screen facing you, remove the card tray. You can use the insertion/removal tool (or a paperclip) to unlock the tray by inserting it into the provided slot. This small hole should be visible on the top part of your device.  
  3. Remove the SIM card from the tray. You can lift the card up from the bottom. To assist, use the opening on the opposite side of the tray to dislodge (using a fingernail or similar tool).
  4. Reinsert the card tray.
  5. Press in on the tray to lock it into place.

After a few moments, with the device still off, reinsert the SIM card and check for the problem.

Galaxy Note10+ mobile data not working fix #10: Check issue on Safe Mode

Third party apps may sometimes cause problems. If mobile data on your Galaxy Note10+ started not working after a new was installed, deleting that might might help. 

If you can’t recall which of the apps may be causing the problem though, consider restarting the device to safe mode instead. 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.

Keep in mind that there’s no shortcut to knowing which app is bad or buggy. Just be patient and keep repeating the cycle above if the problem returns after removing one app. Once the issue stops, the most recent app you deleted must be the culprit. Be sure not to re-install the bad app. You can add the rest of the apps you deleted previously afterwards.

Galaxy Note10+ mobile data not working fix #11: Refresh system cache

In some cases, problems may arise after installing a system update. This may suggests that the cause may be related to a bad system cache. Try to clear the cache partition so the system cache is refreshed. Here’s how to do that:

  1. Turn off the device. This is important as your device won’t boot to Recovery Mode when it’s on.
  2. Press and hold the Volume Up key and the Bixby / Power key.
  3. Once the Android Recovery screen comes up, release the buttons.
  4. Use the Volume Down button until you are highlighting ‘Wipe cache partition.’
  5. Press the Power button to select ‘Wipe cache partition.’
  6. Use Volume Down to highlight Yes.
  7. Press the Power button to confirm the action to clear the cache.
  8. Wait for a second as the system wipes the cache.
  9. Press the Power button again to reboot the device. This will return the device to the normal interface.
  10. That’s it!

Galaxy Note10+ mobile data not working fix #12: Erase the device (factory reset)

The final troubleshooting step that you can do on your device is to factory reset it. If the cause of the problem lies in the software, this may help. Just be sure to create a backup of your files first to avoid losing them.

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.

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 key and the Bixby / Power key.
  5. When the green Android logo displays, release both keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
