1. Verify you have an active data plan

Start by ruling out the most basic cause. Check if you have an active mobile data plan with your carrier and haven’t exceeded your monthly allowance.

This information is usually accessible through your carrier’s app, website, or by contacting their customer support.

2. Check the cellular signal strength indicator

Look for the signal bars in the top right corner of your phone’s screen. Fewer bars indicate weaker reception, which can hinder data connectivity.

Try moving to an open area or an elevated location where the signal might be stronger.

3. Toggle Airplane Mode on and off

This simple action quickly refreshes your network connection, potentially resolving temporary glitches.

  1. Access Quick Settings by swiping down from the top of your screen.
  2. Tap the Airplane Mode icon to enable it.
  3. Wait for a few seconds, then tap the Airplane Mode icon again to disable it.

4. Restart your device

A system reboot clears temporary software issues that can affect many functions, including mobile data.

  1. Press and hold the Power and Volume Down buttons together.
  2. Select Restart.

5. Confirm that mobile data is enabled

Ensure that mobile data is actually switched on in your device settings.

  1. Go to Settings.
  2. Navigate to Connections or Mobile Networks.
  3. Make sure the toggle next to Mobile Data is enabled.

6. Remove and reinsert your SIM card

A loose or damaged SIM card can lead to connectivity problems. Carefully remove your SIM card and reinsert it firmly, ensuring it’s correctly seated in the SIM tray.

7. Update your device software

Software updates often contain bug fixes and performance improvements. Keeping your Samsung Galaxy A25 up-to-date might resolve underlying data connectivity problems.

  1. Open Settings.
  2. Go to Software Update.
  3. Tap Download and Install if an update is available.

8. Check for carrier outages

Sometimes, outages or maintenance on your carrier’s network can cause disruptions in mobile data service. Check your carrier’s website or social media pages for any announcements about known issues.

9. Enable Data Roaming (if traveling)

If you’re traveling outside your usual network coverage area, check that data roaming is enabled.

  1. Open Settings.
  2. Go to Connections.
  3. Enable the Data Roaming toggle.

10. Reset mobile network settings

Resetting your network settings reverts them to defaults, which can solve issues caused by misconfigurations. Note that this will erase saved Wi-Fi networks and Bluetooth connections.

  1. Access Settings.
  2. Go to General Management.
  3. Select Reset.
  4. Tap Reset mobile network settings.

11. Manually select your network carrier

Occasionally, automatic network selection may fail.

  1. Open Settings.
  2. Go to Connections or Mobile Networks.
  3. Tap Network operators.
  4. Disable Select automatically and manually choose your carrier.

12. Verify correct APN Settings

Access Point Names (APNs) contain configuration details for connecting your phone to your carrier’s mobile data network. Incorrect APN settings can prevent your phone from utilizing cellular data.

  1. Contact your carrier for the correct APN settings.
  2. Go to Settings on your phone.
  3. Choose Connections or Network & internet.
  4. Navigate to Mobile Networks.
  5. Select Access Point Names.
  6. Verify the existing APN settings or edit them if necessary.

13. Test with a different SIM card

This solution helps in isolating whether the SIM card itself is defective. If a different SIM card works in your phone and connects to data, the issue likely lies with your original SIM.

  1. Borrow a compatible SIM card from someone with a different carrier, or even one from your carrier, if possible.
  2. Ensure the borrowed SIM card functions on another device that can accept it.
  3. Once verified, carefully remove your current SIM and insert the borrowed SIM into your Samsung Galaxy A25.
  4. Follow the same steps previously indicated to attempt connecting to mobile data.

14. Boot into Safe Mode

Safe Mode temporarily disables third-party apps on your phone. This can help determine if a downloaded app is interfering with your mobile data connectivity.

  1. Press and hold the power button on your phone.
  2. Tap and hold the Power Off option.
  3. When the Safe Mode prompt appears, tap it.

15. Remove your phone case

While uncommon, some bulky phone cases may partially obstruct your phone’s cellular antenna, potentially weakening signal reception and affecting mobile data reliability.

  1. Temporarily remove your phone case.
  2. Test your mobile data connection in an area with a known good signal.

16. Consult a Samsung Repair Center or your cell carrier

If all else fails, visiting a Samsung Repair Center or contacting your carrier’s support can uncover advanced diagnostic tests, and identify whether there’s a hardware issue underlying your cellular data trouble.

17. Factory reset your device

A factory reset restores your phone to its original software state, wiping all data. Do this as a last resort if previously listed solutions failed, and you believe a comprehensive software problem is the root cause.

  1. Back up all important data on your phone, as a factory reset erases everything.
  2. Navigate to Settings.
  3. Find General Management or similar.
  4. Select Reset and then Factory data reset.
  5. Follow the on-screen instructions to complete the reset.
