Why Is Mobile Data Not Working On Samsung Galaxy S20?

With a premium smartphone like Samsung Galaxy S20, you should not worry much about running into serious technical problems. But lately, some users are reporting that mobile data is not working on their Samsung Galaxy S20.

There can be various reasons for this issue.

  1.   Android 11 update
  2.   Core service failure or crash
  3.   Lack of proper network reception
  4.   Minor firmware issues
  5.   Faulty APN settings

The good news is that it can be fixed without breaking any sweat.

How To Fix Mobile Data Not Working On My Samsung Galaxy S20?

Let’s start with the simplest fix to the problem.

1.Force Restart Your Phone

Almost all the technical issues in your smartphone can be fixed with a simple force restart. It is as simple as that.

Oftentimes, the mobile data stops working due to a system crash or failure. In this case, a forced restart will refresh the memory and reload the system. Here’s how you force restart your phone.

  1.   Press and hold the Volume Down and the Power Button simultaneously for 10 seconds. This combination triggers the forced restart in almost all Android smartphones today.
  2.   Your phone will turn off and power back on automatically.
  3.   Release the buttons once you see the Samsung S20 logo on the screen. The reboot is complete.

Voila! Your mobile data should be working now.

2.Reset your APNs

A faulty Access Point Names (APNs) setting can prevent mobile data access in your phone. APNs provides your phone with necessary settings like IP address and gateways to get you online.

Try resetting your APNs with the information provided by your respective mobile service provider. Here’s how you do it:

  1.   Go to Settings > Network & Internet > Mobile Network > Advanced > Access Point Names
  2.   Find the APN that you use for your mobile data.
  3.   Tap the menu icon and “Reset to default”

In most cases, your network service provider will provide you with the required settings by default. However, after an Android software update, you might need to enter your APN settings manually to fix the problem.

  1.   Tap the “+” icon that you can see in the APN list screen as mentioned above
  2.   Enter the required APN details for your mobile data network. Please refer to your respective service provider’s website for the authentic APN settings.
  3.   Save the newly created APN, and activate it by selecting it from the list.

3.Rebooting the Right Way

Yes, there is a right way to reboot your phone when you are facing network issues. Consider the following sequence the next time you reboot your Samsung Galaxy S20.

  1.   Turn on the Airplane Mode before rebooting.
  2.   Turn off your phone (Do not restart)
  3.   Wait for a minute before you power on your phone.
  4.   Turn off the Airplane Mode. Enable the mobile data after 30 seconds.

Enabling and disabling the Airplane Mode before and after the reboot allows the phone to refresh the network scan rather than loading with the same network setting.

The mobile data problem should be resolved by now. If you can still not connect to the internet, you might need to reset network settings or even reset your data, which is explained later in this article.
