If your mobile data is not working or you purchased a Galaxy Note 5 that is unlocked and belonged to a different carrier, you might have to create an APN (Access Point Name) to configure your mobile internet and be able to access cellular data on your Samsung device. An APN is what allows you to access mobile internet with your Galaxy Note 5.
To add a new APN on any Samsung Galaxy Note 5, follow these steps:
Tap on Settings > Mobile networks
- Tap on Access Point Names
- Once on the APN screen, tap on ADD or New APN by tapping on the menu button.
Enter your APN settings (For APN settings click here)
Press the three dots on the top right of the screen, tap on Save in order to save the APN settings.
NOTE: The created APN will show up in the APNs screen after you have saved it. To activate the APN, tap on the radio button located beside it.
Restart the phone and try browsing the Internet.
