Working Fixes for When Your Samsung Phone Keeps Losing Network Connection

If your Samsung phone keeps losing network connection, you can try out some of the working fixes we’ve provided below.

  1. Restart your phone: The first and most basic fix for this issue is to restart your phone. If it is a minor issue, it is almost certain that restarting your phone will do the trick.

After all, restarting a phone helps reboot and reset any processes that may be interfering with its general performance. For example, when you reboot the phone, the reboot process will force close all running apps and help your phone to re-establish its network connection.

  1. Verify the account and services: If your Samsung phone keeps losing network connection, one of the things you can do is to make sure your carrier network is active.

While at it, you should also confirm if you haven’t reached your data usage limits. If you haven’t reached your data usage limit, consider contacting your carrier network to ensure the issue is not from their end.

  1. If you use an external network device, restart it: Sometimes, the problem may not originate from your phone. If you use an external network device such as a modem or router to get network access, the problem may originate from it.

Here are the fixes you can try if you make use of a modem or a router:

  • First, unplug your modem or router from its power source. If you make use of a MiFi, you can turn it off.
  • Leave the device(s) off for 1 or 2 minutes.
  • You can reboot your phone while you keep the external network device off.
  • Plug your external network device back into a power source or turn on your MiFi if that is what you use.
  • Try reconnecting.
  1. Turn Airplane Mode ON and OFF: You can also try to fix the issue by turning Airplane Mode ON and then back OFF. This can help your phone re-establish a connection.

To turn Airplane mode ON and OFF:

  • STEP 1: Pull your phone’s notification panel by swiping down from the top of your Home screen.
  • STEP 2: In some cases, you may be able to locate the Airplane mode icon in the panel tray quickly. For informational purposes, the Airplane mode icon is always in the shape of an airplane.

If you can locate the Airplane mode icon on the tray, tap on it to turn it ON. After turning it ON, tap ON it again to turn it OFF.

If you couldn’t locate the Airplane mode icon in the tray, tap on the “Settings” icon. Then go to “Network & Internet.” You will be able to find the Airplane mode feature there.

  1. Reset your phone’s network settings: When you reset your phone’s network settings, the process will check all your phone’s services to ensure they are running correctly.

Here’s how to reset your Samsung phone’s network settings:

  • STEP 1: Go to your phone’s “Settings
  • STEP 2: Select the “General management” option from the settings page.
  • STEP 3: Tap on “Reset
  • STEP 4: Tap on “Reset network settings.”
  • STEP 5: Tap “Reset settings.”
  • STEP 6: Tap “Reset.”
  1. Manually select your network providers: Your phone may have difficulties finding your network. In that case, you will need to select it manually.

To manually select your network providers:

  • STEP 1: Go to “Settings
  • STEP 2: Select “Connections” from the options.
  • STEP 3: Tap on “Mobile networks
  • STEP 4: Tap on “Network operators.” You will see a list of network providers. Select your network provider.
  1. Check if your SIM card is still in its proper position: Your SIM card is like an address memory that allows a network to find your phone and vice versa. If your phone doesn’t recognize your SIM card, you may experience network issues.

To prevent that, you should check to see if your SIM is making correct contact with your phone’s SIM panel. You can follow the guide below when you want to check to see if your SIM is making correct contact:

  • STEP 1: Turn your phone OFF.
  • STEP 2: Use an ejector tool to take out the SIM card. Try using a paper clip to wipe out any dirt that could be interfering with your SIM’s contact.
  • STEP 3: Re-insert your SIM. Make sure the contact is intact.
  • STEP 4: Turn your Samsung phone back ON to see if it no longer keeps losing network connection.

What Is the Samsung Signal Strength Code?

Your Samsung signal strength code is *#*#197328640#*#* or *#0011#. This code will activate a Field Test Mode on your phone so that you can see your signal strength.

The Field Test Mode will display your phone’s signal strength in dBm (decibels below 1 milliwatt). If the code doesn’t work for you, try using the general signal strength code for Android, which is *#*#7262626#*#*.

Lastly, you can also access your signal strength by following the process below:

  • STEP 1: Open your phone’s “Settings” app.
  • STEP 2: Tap on the “About device” option on the Settings page.
  • STEP 3: When your phone opens a new Setting page, tap on the “Status” option.
  • STEP 4: Tap on “SIM Card status.”
  • STEP 5: Look for the “Check the Signal strength” tab. Inside this tab, you can see your signal strength in dBm.

Note that signal strengths are always negative values. Therefore, (-51) dBm will be a stronger signal than, for example, (-83) dBm.

Top Tips to Improve the Quality of The Internet on Your Samsung Phones

The following tips are useful for improving the quality of the internet on your Samsung phone.

  1. Restart your phone: The first thing you can always try is to restart your phone. Restarting your phone will help reboot most of the ongoing processes.
  2. Close the background apps you aren’t using: When multiple applications run on your internet, those apps will share your network’s bandwidth. The result of this is that your data speed will reduce.

So, close all apps you’re not actively using to optimize your internet speed.

  1. Disable or Uninstall apps you no longer use: It is important that you delete apps you no longer use. This is because these apps consume RAM and storage space even though you don’t use them.
  2. Install an Ad Blocker: You should consider installing an ad blocker because pop-up ads can affect your internet browsing speed.
  3. Update your phone’s operating system: Running outdated software can affect your phone’s functions.

  • STEP 2: Click on “System
  • STEP 3: Then go to “System Update
  1. Switch between 3G, 4G, or 5G network modes: Some network modes may be weak in some areas. Normally, your phone should switch network modes when the signal reception of one mode is weak.

However, your phone is more likely to keep the network mode you have prioritized. Due to this reason, you should try switching between the network modes manually.

To switch your network mode:

  • STEP 1: Go to your “Settings
  • STEP 2: Select “Network & Internet
  • STEP 3: Click on “Mobile network
  • STEP 4: Find the “Preferred network type” option and click on it.
