How to fix Galaxy Note10+ 4G LTE not working | no signal issue

If your Galaxy Note10+ 4G LTE is not working, you want to check a set of possible factors that might cause the problem. Learn what you can do by doing the steps below.

Galaxy Note10+ 4G LTE not working fix #1: Check signal strength

If 4G LTE appears to be not working on your Galaxy Note10+, the first thing that you want to do is check the signal bars. If your device only shows 2 bars at most, weak signal must be the reason for the issue. The speed and quality of your 4G LTE connection largely depends on strength of the signal in your location. If you’re inside a building and there’s barely enough cellular connectivity, mobile data, even on 4G LTE network mode may suffer. Try to see if you have poor signal issue by relocating to a more open area. If the issue disappears, then you know that there’s nothing wrong with your device.

Galaxy Note10+ 4G LTE not working fix #2: Check if voice calling works

Some carriers may have 4G LTE issues which can also affect other network services. Try checking if texting or voice calling are intermittent or having random issues. If they do have a problem even if there’s excellent signal bars, there may be an issue with your network. You must contact your network operator for help.

Galaxy Note10+ 4G LTE not working fix #3: Perform device reboot

Restarting a system like a phone when it has network issues sometimes helps. If you are yet to reboot your Note10+, now is the time to do that. 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+ 4G LTE not working fix #4: Reseat SIM card

Poor SIM card connectivity or SIM card issues may also cause 4G LTE not working on your Galaxy Note10+. Make sure to check if there’s damage to the SIM, or if temporarily disconnecting it can help.

First, make sure to disconnect the SIM card from the phone properly. Here’s how:

  1. Turn off your Galaxy Note10+. This is important. Removing 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.
  6. That’s it!

Once the SIM card has been removed, try to do a quick check if there’s any visible damage to it. Try to also wipe the connectors with dry cloth to ensure that the card is communicating well with the phone. After that, insert the SIM card back with the phone still off and check for the problem.

Galaxy Note10+ 4G LTE not working fix #5: Clear network configuration

Improper network configuration may cause network issues. Make sure that you reset your Galaxy Note10+ network settings if 4G LTE is still not working. Here’s how:

  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+ 4G LTE not working fix #6: Update software and apps

Updating the software and apps can sometimes be a good way to get rid of problems. If your Galaxy Note10+ 4G LTE is still not working at this time, your next move is to keep the software environment up to date. Be default, carrier-branded Note10 and Note10+ should automatically notify owners of available system update. If you got your device as part of your subscription plan, then all you need to do is to tap on notification for update. For global or international versions, you’ll have an option to manually check for system updates. All you have to do is go under Settings > Software update.

To keep apps updated, follow these steps:

  1. Open Play Store app.
  2. Tap More settings icon at the upper left (three-horizontal lines).
  3. Tap My apps & games.
  4. Tap Update or Update All.

Galaxy Note10+ 4G LTE not working fix #7: Disable Roaming

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+ 4G LTE not working fix #8: Manually 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+ 4G LTE not working fix #9: Disconnect from network

If your Galaxy Note10+ 4G LTE 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+ 4G LTE not working fix #10: Run device on Safe Mode

A bad third party app may interfere with Android. To check if you have installed this kind of app, restart your device to safe mode. While running on safe mode, apps you downloaded and not part of the original software can’t run. They’ll be greyed out in your home screen. Only apps that come with the original software can be launched. So, if 4G LTE works normally on safe mode only, a bad app must be 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.

Galaxy Note10+ 4G LTE not working fix #11: Clear cache partition

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+ 4G LTE not working fix #12: Erase the device (factory reset)

Some network issues may require erasing the device or factory reset. If none of the solutions above has worked so far, this potential solution might help. Factory reset is often effective in resolving issues coming from software problems. 

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 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).
  6. The Recovery screen menu will now appear. When you see this, release the buttons.
  7. Use the Volume Down button until you are highlighting ‘Wipe data/factory reset.’
  8. Press the Power button to select ‘Wipe data/factory reset.’
  9. Use Volume Down to highlight Yes.
  10. Press the Power button to confirm the action to clear your phone data.

Galaxy Note10+ 4G LTE not working fix #13: Get help from carrier

The final troubleshooting step to do if your Galaxy Note10+ 4G LTE network is still not working is to seek help from your carrier. By doing a factory reset, you’ve basically returned the software to its original, known working state. If nothing changes after a factory reset though, you can assume that the cause is deeper, probably hardware-related. To get support, contact your network operator.
