To turn on and use mobile data, you must have a good mobile signal reception in your area, a mobile data package covering your requirements (Social media, Gaming, General internet browsing, Torrenting, etc.), correctly set up network profile in your device, and smoothly running operating system without bugs and glitches.

If mobile data is not working on your Samsung Galaxy S20, you first need to rule out possible external causes such as insufficient data balance, poor signals, and network outages. Then troubleshoot device settings and other hardware issues that might exist in your phone.

This article will guide you through the step-by-step process to fix if mobile data isn’t working on your Galaxy S20. Start with Fix 01.

Fix 01: Restart Your Phone

By restarting your Samsung Galaxy S20, you can fix temporary software glitches that may be causing the mobile data to not work. To restart your phone, follow the steps below:

1. Press and hold the power button and volume down button to bring the power menu.

2. Tap on the power off button to turn off your phone.

3. Wair for 2 minutes and then power on the phone again.

Fix 02: Contact Your Network Provider

By contacting the network provider, you need to verify these 04 things:

1. You have an activated mobile data package.
2. Your plan covers your requirements. Some plans do not allow certain tasks (ex: downloading torrents).
3. Your mobile data package has not expired or is due.
4. Signal strength is not weak for your network in your area.

These things are crucial for mobile data to work correctly. If there is any issue with one of the 04 things I mentioned above, you need to fix it to resolve your mobile data issue.

Fix 03: Check APN Settings

APN (Access Point Name) settings allow your phone to connect to your carrier and access the internet to send/receive data. If APN settings are not properly configured, you won’t be able to access the internet using your phone.

To check and correctly configure the APN settings, you can contact your network provider and ask them to send you the correct APN settings through a configuration message. 

Once your Galaxy S20 receives the APN settings message, it will automatically update the current settings to match with the carrier’s settings and fix the mobile data not working issue.

Fix 04: Change Mobile Network Mode

Samsung Galaxy S20 supports 2G/3G/4G/ and 5G network modes. You can change the current network mode to a different one available to match the signal reception in your area.

To change the network mode, follow the steps below:

1. Go to Settings.
2. Tap on “Connections”.
3. Tap on “Mobile networks”.

4. Tap on “Network mode”.

5. Change the network mode from the current one to a different one.
6. Restart the phone.

Fix 05: Reset Network Settings

If the network settings on your Galaxy S20 are not configured correctly, it can cause mobile data to not work. By resetting network settings, you can fix such potential issues.

Follow the steps below to reset network settings on your Samsung Galaxy S20:

1. Go to Settings.
2. Scroll down and tap on “General management”.

2. Then tap on “Reset”.

3. Select “Reset network settings”.

4. Read the warning message and confirm the reset.
5. Wait for your phone to restart.

Fix 06: Do a Software Update

1. Open Settings.
2. Scroll down and tap on “Battery and device care”.
