Understanding 3 (Three) APN Settings
How APN Works
APN settings act as a gateway between your phone and 3’s mobile network. The correct APN ensures your device can:
✔ Connect to the internet using mobile data.

✔ Use VoLTE (Voice over LTE) and Wi-Fi Calling.
Why Your Device May Require Manual APN Setup
- SIM card change or switching to a new phone.
- Factory reset or software update that resets network settings.
- Imported devices that do not auto-configure APN settings.
- Incorrect default APN type settings causing slow speeds or connection drops.
Benefits of Configuring the Correct APN
✅ Faster and more stable internet speeds.
✅ Fixing VoLTE, Wi-Fi Calling, and MMS issues.
✅ Seamless online gaming and HD streaming without buffering.
