Enabling advanced calling features on your iPhone 6 Plus can significantly enhance your calling experience by allowing HD Voice, Wi-Fi calling, and more. These features improve call clarity, enable calls over Wi-Fi when cellular service is weak, and offer better overall communication quality. Before you start, ensure your carrier supports these features and that your iPhone 6 Plus is running the latest available software version. Since the iPhone 6 Plus is an older device, some advanced calling features may have limited availability, but many can still be enabled with proper setup.
What You’ll Need
- An unlocked or carrier-supported iPhone 6 Plus
- Active SIM card with cellular service
- Stable Wi-Fi connection (for Wi-Fi calling)
- Latest iOS version installed (iOS 12.4.9 or earlier, as supported)
- Carrier support for advanced calling features (check with your provider)
Step-by-Step
- Ensure your iPhone 6 Plus is updated to the latest compatible iOS version. Go to Settings > General > Software Update. If an update is available, follow on-screen instructions to install it.
- Verify that your carrier supports advanced calling features like HD Voice and Wi-Fi calling. Contact your carrier or visit their support website for confirmation.
- Insert your active SIM card into your iPhone 6 Plus if not already inserted. Turn on your device and ensure it connects to the cellular network.
- Navigate to Settings > Cellular > Cellular Data Options. If you see an option for ‘Enable LTE,’ tap it and select ‘Voice & Data’ to activate LTE for voice calls, which is necessary for HD Voice.
- Return to Settings > Phone. Look for the option labeled ‘Wi-Fi Calling.’ If it’s available, toggle the switch to turn it on.
- If prompted, enter your emergency address for Wi-Fi calling, especially if you’re in the United States, to comply with FCC regulations.
- Once enabled, your iPhone may restart or refresh network settings. Afterward, you should see a ‘Wi-Fi’ label next to your carrier name in the status bar when connected to Wi-Fi, indicating Wi-Fi calling is active.
- Test the features by making a call over Wi-Fi or checking if HD Voice is active during a call. You can do this by calling a contact and observing the call quality or the ‘HD’ indicator on your call screen.
