This article outlines effective solutions for fixing “no mobile data” and “no network connection” issues on Samsung smartphones. From software and operating system tips to hardware fixes, these steps aim to restore mobile data functionality on your device.

Why Is Mobile Data Not Working on Samsung?

Mobile data issues on Samsung smartphones often arise from specific settings, like Airplane Mode being enabled or incorrect preferences set after changing mobile carriers.

Problems can also stem from a damaged SIM card or cellular network outages.

How to Fix No Mobile Data on a Samsung

Follow these steps in order from easiest and fastest to more complex and time-consuming:

1. Turn off Airplane Mode. When enabled, Airplane Mode disables mobile, Bluetooth, and Wi-Fi connections.

2. Toggle Airplane Mode. Enable it for about 30 seconds, then disable it to reset your wireless connections and potentially fix the problem.

3. Disable Wi-Fi. Smartphones often prioritize Wi-Fi over mobile data, even with poor Wi-Fi connections.

4. Restart your Samsung device. A simple restart can resolve many connectivity issues.

5. Update your Samsung phone’s operating system. An important update may be required for network connectivity. Connect to Wi-Fi before updating.

6. Check if your service provider is down. Your provider’s social media or website often provides information on major outages.

7. Review your mobile account. Log in to your provider’s website to ensure there are no warnings or notifications affecting connectivity.

8. Verify network coverage. Ensure you are within your provider’s service area.

9. Switch network connections. If 5G is problematic, try connecting to 4G LTE or 3G.

10. Reinsert your SIM card. Remove, inspect for damage, and firmly reinsert your SIM card.

11. Test with another SIM card. Using a friend’s SIM can help determine if your SIM is faulty.

12. Reset network settings. Resetting removes records of used networks and passwords, often fixing errors.

13. Reset the APNs. Reset if you’ve changed carriers to ensure correct settings.

14. Unlock your Samsung phone. Ensure your phone is unlocked if switching providers.

15. Factory reset your Samsung phone. As a last resort, returning to factory settings removes all data and settings to potentially resolve issues.
