But don’t worry, you’re not alone! Many Samsung Galaxy users experience this issue, and fortunately, there are several troubleshooting steps you can take to regain a strong and stable connection.

Check Your Surroundings and Account

Before diving into your phone’s settings, it’s essential to consider external factors that might be affecting your signal. External factors can sometimes affect your signal strength.

Check your account: Ensure your account is active and in good standing with your service provider. Verify that you haven’t exceeded your data limit or have any outstanding bills that might be affecting your service.
Check for outages: Visit your carrier’s website or social media channels to see if there are any reported network outages in your area. Outages can cause widespread signal loss, and if there’s one in your region, all you can do is wait for your carrier to resolve it.
Check your cellular service provider’s status: It’s also a good idea to check if your cellular service provider is experiencing any temporary disruptions or technical difficulties. Their official website or customer support channels can provide information about potential service interruptions.
Check your coverage: Even without an outage, your location might have inherently weak cellular coverage. Areas with limited cell tower infrastructure, such as rural settings or places with natural obstructions like mountains or valleys, can experience poor signal strength. If you’re indoors, try moving closer to a window or going outside to see if your signal improves.
Consider physical obstructions: Buildings, especially those with metal or concrete structures, can significantly interfere with cellular signals. If you’re inside a building, try moving to a higher floor or a location with fewer obstructions.

Contact Your Carrier

If you’ve tried some basic troubleshooting steps and are still experiencing signal issues, it’s a good idea to contact your carrier. They can help you determine if there’s a problem with your account, SIM card, or network coverage in your area. They might also be able to provide further assistance or suggest solutions specific to your device and plan.

Basic Troubleshooting Steps

If your surroundings, account, and carrier aren’t the issue, it’s time to start troubleshooting your Samsung Galaxy phone itself. Here are some basic steps to try:

Restart your phone: This classic troubleshooting step can often resolve minor software glitches that might be causing signal loss. To restart your phone, press and hold the power button, then tap “Restart.”
Toggle Airplane mode: Turning Airplane mode on and off can reset your phone’s network connections and help it re-establish a connection with the nearest cell tower. To do this, swipe down from the top of the screen to open the Quick Settings panel and tap the Airplane mode icon to turn it on, then tap it again to turn it off.
Inspect the SIM card: Before removing and reinserting your SIM card, visually inspect it for any signs of damage, such as scratches or bent connectors. A damaged SIM card can cause signal problems. If you notice any damage, contact your carrier for a replacement.
Remove and reinsert your SIM card: If your SIM card appears to be in good condition, a loose or improperly seated SIM card can also cause signal problems. To reinsert your SIM card, power off your phone, use a SIM ejector tool (or a small paperclip) to remove the SIM tray, ensure the SIM card is correctly placed in the tray, and reinsert the tray.
Restart your router/modem: If you’re experiencing signal issues specifically when connected to Wi-Fi, restarting your router or modem can often resolve the problem. This helps refresh the network connection and eliminate any temporary glitches.
Check for software updates: Outdated software can sometimes lead to signal issues. To check for updates, go to Settings > Software update > Download and install.

Advanced Troubleshooting Steps

If the basic steps haven’t resolved the issue, you can try these more advanced troubleshooting methods:

Reset network settings: This will erase all your saved Wi-Fi networks, Bluetooth connections, and cellular network settings. To reset network settings, go to Settings > General management > Reset > Reset network settings.
Check your mobile network settings: Go to Settings > Connections > Mobile networks and verify the following:

Network mode: Ensure it’s set to a suitable option for your area, such as 5G/LTE/3G/2G (auto connect) or LTE/3G/2G.
Network operators: Make sure your phone is connected to the correct network operator. If not, select it manually.
Reset the Access Point Name (APN): The APN is a set of settings that allows your phone to connect to your carrier’s mobile network. Incorrect APN settings can cause signal problems. To reset your APN settings, go to Settings > Connections > Mobile networks > Access Point Names > More options > Reset to default.

Check your mobile data usage: If you’ve exceeded your monthly data allowance, your carrier might have throttled your data speeds. While data throttling primarily affects data speeds and not signal strength, it can still impact your ability to make calls or use data-intensive apps. Contact your carrier to check your data usage and consider upgrading your plan if needed.
Change the network mode: If you’re in an area with weak 5G coverage, switching to 4G/LTE might improve your signal and data speeds. To change the network mode, go to Settings > Connections > Mobile networks > Network mode and select 4G/LTE or 3G/2G (auto connect).
Clear the cache from network-related apps: Clearing the cache from apps that use mobile data, such as Google Play Services, can sometimes resolve connectivity issues⁸. To clear an app’s cache, go to Settings > Apps > Select the app > Storage > Clear cache.
Use the Samsung Members app for diagnostics: The Samsung Members app includes diagnostic tools to test your SIM card and network connectivity. This can help you identify potential problems and find solutions.

Other troubleshooting steps

Try a different SIM card: If you have another SIM card from the same carrier or a different carrier, try inserting it into your phone. This helps determine if the issue lies with your SIM card or your phone.
Factory reset your phone: This is the most drastic step and should only be used as a last resort. It will erase all data on your phone, so make sure to back up your important files before proceeding. To factory reset your phone, go to Settings > General management > Reset > Factory data reset.

Troubleshooting for Specific Issues

Android 14 and One UI 6.1

If you’re using a Samsung Galaxy device with Android 14 and One UI 6.1, you might encounter specific issues related to mobile data. Here are some troubleshooting steps to try:

Exit Maintenance mode: If your phone is stuck in Maintenance mode, you can exit it through the Notification panel or the search bar in the Apps screen.

Notification panel: Swipe down from the top of the screen, tap the “Your phone/tablet is in Maintenance mode” notification, tap “Exit,” and then tap “Restart.”
Search bar: Go to the Apps screen, enter “Maintenance mode” in the search bar, tap “Maintenance mode” in the results, tap “Maintenance mode” again, tap “Exit,” and then tap “Restart.”

Key Insights from Research

Here are some key insights from the research that can help you understand and address signal loss on your Samsung Galaxy phone:

Recent security updates might be a cause for signal loss. If you recently updated your phone’s software and started experiencing signal problems, the update might be the culprit. Consider delaying future updates or checking for bug fixes from Samsung.
Hardware issues could be the underlying cause of persistent signal loss. If software troubleshooting doesn’t resolve the issue, there might be a problem with your phone’s antenna, motherboard, or other hardware components. In such cases, it’s best to contact Samsung support or visit an authorized service center for professional repair.
The type of phone case being used can affect signal strength. Some phone cases, particularly those made of carbon fiber, can interfere with cellular reception. If you’re using a carbon fiber case, try removing it to see if it improves your signal.

Conclusion

A Samsung Galaxy phone that keeps losing signal can be a major inconvenience, but with the right troubleshooting steps, you can often resolve the issue and enjoy a stable connection. By checking your surroundings, trying basic and advanced troubleshooting methods, and contacting your carrier if needed, you can regain control of your phone’s signal and stay connected. Remember to be patient and persistent, and with a little effort, you’ll likely find the solution that works best for your Samsung Galaxy phone.
