What is APN and Why is it Important?
An Access Point Name (APN) is a network configuration setting that allows your Samsung Galaxy device to communicate with your carrier’s mobile data network. Without the correct APN, you may experience:
- No internet connection, even with an active data plan.
- MMS (Multimedia Messaging Service) messages failing to send or receive.
- VoLTE (Voice over LTE) and Wi-Fi Calling not working.
If you reset your phone and find that your APN settings are missing or greyed out, follow this guide on fixing greyed-out APN settings.
