Fix: Samsung Galaxy Z Flip 5 / Z Fold 5 No Internet or Slow Data Connection 

The Samsung Galaxy Z Flip 5 and Z Fold 5 are great devices that show how far we have reached regarding smartphone innovation. Both are great phones; however, these foldables are not without issues like any other smartphone. Since the initial release, many users have gotten their hands on the Samsung Galaxy Z Flip 5 and Z Fold 5 handsets.

However, many users are frustrated due to the lack of internet and slow data connection issues. Many users on Reddit and the Samsung Community have raised this issue with their Galaxy Z Flip 5 and Z Fold 5. Internet issues, especially when there is no internet or slow data connection, are extremely frustrating.

If you are facing the same issue on your Galaxy Z Flip 5 or Z Fold 5, you are in the right place. Here, we will show you how to fix this issue and get back to using the internet on your Galaxy Z Flip 5 or Z Fold 5. This is an extensive guide, so you should be able to find the right solution for you.

Test Your Network Speed

Testing your network speed is an important first step in troubleshooting data connection difficulties with the Samsung Galaxy Z Flip 5 or Z Fold 5. Checking this can help narrow down the cause of the problem to either your device or the app’s server.

In other words, this will check if the app you are trying to use is having server issues. Follow the steps below:

1. Launch a web browser or a speed test app if you have one installed.
2. Start the speed test website or app by typing “speed test” into your search bar.
3. Click the “Start” button to begin the test.
4. Hold off until the test is over. Ping, latency, and download/upload rates are all common metrics to check during this procedure.
5. Keep an eye on your ping in milliseconds (ms) and download and upload rates in megabits per second (Mbps).

Evaluate your test results in light of your average network speed. If your data transfer rates are noticeably lower than usual, there may be an issue with the network itself rather than with your device. Otherwise, there is an issue with the app you’re trying to use.

20 Ways to Fix Samsung Galaxy Z Flip 5 / Z Fold 5 No Internet or Slow Data Connection

Now that you have concluded that you have an issue with the internet on your Samsung Galaxy Z Flip 5 or Z Fold 5, we can start fixing the issue. This is an extensive list of fixes, so be sure to try all of them, and you will be able to fix the data connection issue on your Galaxy Z Flip 5 or Z Fold 5.

Fix 1: Turn ON and Turn OFF Airplane Mode

The first step to resolving any issues with the slow data connection on your Galaxy Z Flip 5 or Z Fold 5 is to turn on and off the Airplane mode. This will help reset the data connection and resolve any temporary or minor glitches that could be the culprits. Follow the steps below to do this:

1. Swipe down from the top to access the Quick Settings panel.
2. Tap on the Airplane mode icon (an airplane silhouette). This should turn it on.
3. Wait for a few seconds and tap on the icon again to turn it off. The icon should turn gray now.

Fix 2: Check your Signal Strength

Next up, you should check your signal strength. Your data connection speed greatly depends on your signal strength. If the signal strength is low or unreliable, then your Samsung Galaxy Z Flip 5 or Z Fold 5 might have slow data or no data at all.

Check your status bar and the number of signal bars. The greater the number of bars, the stronger the connection. Make a note of the signal strength and evaluate it against what you usually receive where you are.

If your signal is extremely weak or nonexistent, you may be in a place with poor network coverage. If the signal is poor, you may want to try switching locations.

Contact your mobile service provider if your signal is regularly weak in regions where you should have adequate coverage. They’ll know about any network faults in your area and how to fix them.

Fix 3: Select the Right SIM Card

We often forget things, especially when we are frustrated. Many users tend to select the wrong SIM card when using mobile data. Just make sure you are using the SIM card that you usually use for data connection. Follow the steps below:

1. Open the Settings app on your Galaxy Z Flip 5 or Z Fold 5.
2. Tap on Connections.
3. Now, tap on the SIM manager option.
4. Finally, tap on Mobile data and select the right SIM card (SIM 1 / SIM 2).

Fix 4: Check your Internet / Data Plan

If you’re still having problems with your Samsung Galaxy Z Flip 5 or Z Fold 5’s internet or slow data connection, make sure you have an active data plan. If you have an active data plan, you can consider upgrading your data plan.

Check if you have exhausted your daily data quota. Also, check if you have used all of your monthly data quota. You may experience slower download speeds or incur additional costs if you go over your data limit.

If you have questions about your plan or how much data you are using, contact your carrier or go to their website. If you often have slow speeds or use up all your data, you may need to update your plan. You might want to get a plan that costs more but gives you more data.

Fix 5: Turn ON Data Roaming

If your Samsung Galaxy Z Flip 5 or Z Fold 5 has trouble staying connected, especially when you’re going abroad, turning on Data Roaming can help. With Data Roaming, your phone can connect to cellular networks in countries other than your own. Follow the steps below:

Note: Data roaming can cause additional charges. Contact your carrier for more information.

1. Make sure to turn on Mobile data first.
2. Now, open the Settings app.
3. Tap on Connections.
4. Then, tap on Mobile networks.
5. Finally, turn on the toggle next to Data roaming.

Depending on your device and provider, you may get a warning about possible roaming charges. Before you move on, make sure you know how much traveling costs with your plan.

Once Data Roaming is turned on, your device will look for networks when you’re in a place where your home carrier’s signal is weak or doesn’t work at all. This way, the data connection speed issue should be resolved.

Fix 6: Force Restart your Phone

Now, if you are still having problems with the Samsung Galaxy Z Flip 5 or Z Fold 5’s internet or slow data connection, you can try a force restart. This is also called a hard reset, but this will not delete any of your data. Make sure you try this solution, as it will help fix any minor issues with the software. Follow the steps below:

1. Press and hold the Volume Down and Power buttons on your phone. This will bring up the Power off menu.
2. Tap on Power off and wait for your device to shut down completely.
3. Now, press and hold the Volume Down and Power buttons again to turn your phone back on.
4. Release the buttons once the Samsung logo appears.
5. On the following startup, check to see if the no internet and slow data connection issue has been resolved.

Fix 7: Don’t Use 5G

5G is still rather new and is developing quickly. Although 5G has been shown to significantly increase data transfer rates and connections, it is still being rolled out and optimized in many areas. While 5G may be available in major cities, it may not reach more rural or outlying places.

Signal strength and reliability can vary even within covered areas. Moreover, because 5G uses higher frequency bands, it is more likely to be disrupted by things like buildings and trees. This disruption can weaken the reliability of the connection.

Therefore, if you’re having trouble connecting to 5G, switching to a different network mode, such as 4G LTE or 3G, may help you maintain a more stable connection. Here’s how to switch to LTE:

1. Open the Settings app on your Galaxy Z Flip 5 or Z Fold 5.
2. Tap on Connections.
3. Now, tap on Mobile networks.
4. Here, tap on Network mode SIM 1 or Network mode SIM 2.
5. Select LTE/3G/2G (auto connect) from the options.
6. The setting will give preference to 4G LTE connections over 5G.

Fix 8: Turn OFF Data Saver

Data Saver is a feature available on your Galaxy phone that helps save data by preventing apps from accessing it in the background. However, it may affect the functionality of some of your apps, especially those that rely on the internet or data. Consider disabling Data Saver for individual apps or disabling it altogether. Follow the steps below:

1. Open the Settings app on your Galaxy Z Flip 5 or Z Fold 5.
2. Tap on Connections.
3. Then, tap on Data usage.
4. Select Data saver.
5. Toggle the switch next to “Turn on now” to the off position.

You can do that if you want to turn off the data saver only for certain apps. This is a great feature for apps like web browsers and media players that depend on a constant data connection. Just follow the steps below:

1. Open the Settings app on your Galaxy Z Flip 5 or Z Fold 5.
2. Tap on Connections.
3. Then, tap on Data usage.
4. Select Data saver.
5. Select “Allowed to use data while Data saver is on” at the bottom of the screen.
6. Then, tap on the three dots and select either “Show system apps” or “Show allowed apps first” to filter the results.
7. Finally, turn on the toggle next to the app you want to enable data usage for when Data Saver is on.
8. After you have turned off the data saver, check to see if the issue has been resolved.

Fix 9: Turn OFF Data Limits

We often get carried away and use too much data. Perhaps this is the reason why you are unable to use any more data. If you’ve hit your data limit on your Samsung Galaxy Z Flip 5 or Z Fold 5, you may be able to resolve issues with mobile data by changing your data limitation settings.

Ideally, you should receive a notification saying that you have reached your data limit. Tap on it and skip to Step 3. If you didn’t receive any such notification or if you have cleared it, follow the steps below.

1. Open the Settings app on your Galaxy Z Flip 5 or Z Fold 5.
2. Tap on Connections.
3. Then, tap on Data usage.
4. Tap on Mobile data usage.
5. Now tap on the three dots in the upper right corner of the screen and select Data limit.
6. Make sure to turn off the “Set data limit” toggle.

Limiting your data usage might help you keep track of your consumption and prevent costly overages. Turning off data limits, however, can fix the problem if you notice that your mobile data stops working after you’ve reached it. Now, even if you’ve maxed up your monthly data limit, your smartphone can still access the internet via mobile data.

After removing data restrictions, it’s important to make sure your mobile data connection is back up and running smoothly on your smartphone. If your data limit setting was preventing you from using mobile data after you hit your limit, this should be it.

Fix 10: Turn OFF and Turn ON Your SIM Card

If your Samsung Galaxy Z Flip 5 or Z Fold 5 is still having problems connecting to mobile data, try turning it off and then turning it back on your SIM card. Doing so can fix your mobile network connection. Follow the steps below:

1. Open the Settings app on your Galaxy Z Flip 5 or Z Fold 5.
2. Tap on Connections.
3. Now, tap on the SIM manager option.
4. Turn off the toggle next to SIM 1 or SIM 2 to disable your SIM card.
5. Turn on the toggle back again to enable your SIM card.
6. Your phone will reconnect to the mobile network automatically.

Fix 11: Reset the APN

Resetting the APN settings to their factory defaults restores the original configuration from your carrier. If you’re having data or internet connectivity troubles, it could be because your APN settings are incorrect or corrupt. Follow these steps to reset the APN settings:

1. Open the Settings app on your Galaxy Z Flip 5 or Z Fold 5.
2. Tap on Connections.
3. Now, tap on Mobile networks.
4. Locate Access point names (or APN) and click it.
5. Now, tap on the three dots in the upper right corner of the screen and select Reset to default.
6. Restart your phone.

Test your data and internet connection after resetting the APN to see whether it has improved. It could take a few seconds for your device to reconnect after you change the APN settings.

Fix 12: Check for Software Updates

Maintaining peak performance and fixing any connectivity issues with your Samsung Galaxy Z Flip 5 or Z Fold 5 requires keeping the software up to date. Many concerns, such as those involving lost data or a sluggish internet connection, can be fixed by simply updating the software’s latest version. Follow the steps below:

5. Once the update is installed, restart your phone for it to take effect.

After installing the update, test your data and internet connections to see whether they have improved.

Fix 13: Reset your Network Settings

If you are still having trouble, it’s time to reset your network settings. This procedure resets your network settings to their factory defaults and fixes any configuration errors. The steps to reset your network settings are as follows:

Note: All your saved network configurations, including Wi-Fi networks, Bluetooth devices, and VPNs, will be erased.

1. Open the Settings app on your Galaxy Z Flip 5 or Z Fold 5.
2. Tap on General management.

Check your data and internet connection after resetting your network settings to determine if the problems persist. If the problems still persist, move on to the next solution.

Fix 14: Clean and Re-insert Your SIM Card

Your Samsung Galaxy Z Flip 5 or Z Fold 5’s SIM card could be at fault if you still have no internet or slow data connection. The SIM card’s ability to function can be impaired if dust or debris has settled on its contacts. Here’s how to remove your SIM card, clean it, and reinsert it:

1. Find the slot for the SIM card. It’s probably on the side of your device, and you can probably access it with a paperclip or SIM card ejector tool.
2. Remove the SIM card tray carefully.
3. Take out your SIM card from its slot.
4. Make sure the SIM card is clean and undamaged. Using a lint-free cloth or an alcohol wipe, carefully remove any debris from the SIM card’s contacts, if necessary.
5. Now, slot it back into the SIM card tray.
6. Restart your phone.

Fix 15: Check Your SIM Card on Another Phone

If your Samsung Galaxy Z Flip 5 or Z Fold 5 still has no internet or slow data connection after you’ve tried the aforementioned solutions, you should check your SIM card on another phone. This can help you figure out if the SIM card is malfunctioning or if the phone is at fault. Follow these steps:

1. Find the slot for the SIM card. It’s probably on the side of your device, and you can probably access it with a paperclip or SIM card ejector tool.
2. Remove the SIM card tray carefully.
3. Take out your SIM card from its slot.
4. Put the SIM card in a different phone.

Turn on that phone and check if it can connect to the network and use mobile data with your SIM card. If the second phone also has connectivity troubles, the SIM card or your carrier’s service is likely to blame.

However, if the other phone can use your SIM card without any problems, the problem may be with your Samsung Galaxy Z Flip 5 or Z Fold 5 itself. Move on to the next solution.

Fix 16: Use Safe Mode

Using Safe Mode on your Samsung Galaxy Z Flip 5 or Z Fold 5 can help you determine if a third-party app is the source of persistent connectivity troubles. By switching to Safe Mode, you can temporarily disable all third-party programs to see if one of them is causing the connection issues. Follow these steps:

1. Hold the Power button down until you see the Power off menu.
2. Once you see the power off the menu, tap on Power off.
3. Now, press and hold the Power button and the Volume Down buttons simultaneously for a few seconds.
4. Release only the Power button once you see the Samsung logo. Don’t let go of the Volume Down button.
5. Your phone should now boot up in safe mode. The words “Safe Mode” should appear in the screen’s lower left corner.

Check your internet or data connection while in Safe Mode to see if the problems still exist. If the issues disappear when switching to Safe Mode, it’s probably a malicious third-party app that’s causing the issue.

You can get out of Safe Mode by performing a normal restart. Hold the power button down and choose “Restart.”

Once you’ve determined which program is causing the connectivity problems, you can delete or update it. If you’re having problems with your device and you’re not sure if it’s because of a third-party app, Safe Mode can help you figure it out.

Fix 17: Reset your Phone (Optional)

If you’ve tried everything else and are still unable to resolve the no internet or slow data connection issue, resetting your Samsung Galaxy Z Flip 5 or Z Fold 5 to factory settings should be your last resort.

Performing a factory reset will restore your device to its default settings and delete all of your personal data. Follow the steps below:

1. Open the Settings app on your Galaxy Z Flip 5 or Z Fold 5.
2. Tap on General management.
3. Then, tap on Reset > Factory data reset.
4. Read the on-screen warnings about the apps, data, and settings that will be removed before proceeding.
5. If you are sure you want to continue, then select Reset.
6. You may be prompted to enter your PIN, password, or pattern. Do so to proceed.
7. Finally, tap on Delete all.
8. The process of resetting your smartphone will begin. This could take a few minutes. As soon as it finishes, your phone will restart.
9. Set up your device again and see if the issue has been resolved.

Although it may seem extreme, sometimes the only way to fix an issue that won’t go away is to reset the device to its factory settings. Back up your data first, and only try this if you’ve tried everything else and still can’t get things to work. As soon as the reset is complete, you should check the network connection.
