How to connect to 3 Wi-Fi in underground?

Connecting to THREE Underground Wi-Fi on Android

Accessing reliable internet connectivity in underground environments can be challenging. However, with THREE’s underground Wi-Fi network, staying connected is now possible. This guide provides a straightforward walkthrough for connecting your Android device to the THREE_WIFI network.

Before you begin:

• Ensure you are within range of the THREE underground Wi-Fi network. The signal strength may vary depending on your location within the underground structure.
• Have a THREE SIM card activated and installed in your Android device. This is crucial for authentication.

Connecting to THREE_WIFI:

1. Enable Wi-Fi: On your Android device, navigate to your settings and ensure Wi-Fi is turned on. You’ll usually find this in the “Connections” or “Network & internet” section.

2. Locate the THREE_WIFI network: Your device will begin scanning for available Wi-Fi networks. Look for a network named “THREE_WIFI” or a similar variation. The exact name might vary slightly depending on the location.

3. Select the THREE_WIFI network: Tap on the “THREE_WIFI” network to select it.

4. Configure the connection settings: This is the most crucial step. You will need to specify the authentication method. Different Android versions may present this slightly differently, but the core settings remain the same. You’ll likely see options to configure the following:

   • Security/Authentication: Select “EAP” (Extensible Authentication Protocol). This is the authentication method used by THREE’s underground Wi-Fi.

   • EAP method: This is where you select the authentication type. Choose “SIM” (Subscriber Identity Module). This uses your THREE SIM card for authentication.

   • Other settings: You might encounter other options such as “CA Certificate” or “Phase 2 Authentication.” In most cases, you can leave these settings at their defaults. If you encounter issues, consult the THREE support documentation or website for further assistance. Forcing incorrect settings here can prevent a connection.

5. Connect: Once you’ve configured the settings correctly, tap the “Connect” button. Your device will attempt to authenticate using your THREE SIM card. This might take a few moments.

6. Troubleshooting: If you experience difficulties connecting, consider the following:

   • Signal strength: Ensure you are within a reasonable range of the THREE_WIFI network. Moving closer to a potential access point might improve the connection.
   • SIM card: Verify that your THREE SIM card is correctly installed and active.
   • Airplane mode: Make sure Airplane mode is turned OFF.
   • Restart: Restart your Android device and try again.
   • THREE support: Contact THREE customer support for assistance if the problem persists.

By following these steps, you should be successfully connected to THREE’s underground Wi-Fi network.
