How To Fix Samsung Galaxy J3 APN Setting Is Greyed Out

Problem: I am really hoping someone can help me, I have been reading forums all day with no clear answers. I purchased a Samsung J3 from Costco, I was using it on the telus network previously and I have currently changed my provider to Rogers. Phone is working for calls and texts but no data I was advised to go in and change my APN, but when I get to the settings>network connections>Mobile networks >> access points. My option to change it is greyed out. I swear I had this issue prior to when I set up with Telus and they were able to get it working. Now however I have spoken to Rogers several times and even gone to the Rogers store and they can’t help me. I’m feeling very stressed out so if anyone has an answer to this or knows if I can be rectified please let me know.

Solution: Before performing any troubleshooting steps on the phone it’s best to make sure that it is running on the latest software version. If an update is available then I suggest that you download and install it first.


One of the reasons why the APN setting is greyed out is due to a restriction in the phone software which could just be a glitch. To fix this follow the troubleshooting steps listed below.

Perform a Soft Reset

The first thing you should do in this case is a soft reset. This is usually done when the phone is unresponsive or when it suffers from a minor software glitch as its software will be refreshed.

  • Press and hold the Power and Volume down key for up to 15 seconds.
  • Wait as the device restarts.

In case your phone model has a removable battery then  just remove the battery then press and hold the power button for at least a minute. Reinsert the battery then turn on the phone.

Try to check if you are now able to change the APN settings.

Wipe the cache partition of the phone

If the soft reset you performed does not fix the problem then the next step is to wipe the cache partition of the phone. This will delete the temporary data stored by the phone software which if corrupted can cause this problem.

  • Turn off the phone.
  • Press and hold the Volume Up and Home keys.
  • Press and hold the Power key until the device vibrates, then release it. Keep pressing the Volume Up and Home keys the entire time.
  • When you see the Android Recovery screen, release the Volume Up and Home keys.
  • Use the Volume keys to scroll down to Wipe cache partition, then use the Power key to select it.
  • Use the Volume keys to scroll down to Yes, then use the Power key to select it.
  • Use the Volume keys to scroll down to Reboot system now, then use the Power key to select it.

Perform a factory reset

One last troubleshooting step to consider is a factory reset. This will revert the phone back to its original factory condition and will usually fix the problem in case is is caused by a software glitch.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only the Power key
  • When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

Once the reset is complete immediately check if you can change the phone APN settings. If it still can’t be accessed then this might be blocked by the phone’s current firmware version. You can try flashing a different stock firmware file to the phone to fix the problem. You can download the firmware file from the Sammobile website. Instructions on how to flash your phone can also be found at this website.
