How Do I Set Up WiFi Calling on My iPhone 15?

Step 1: Ensure Compatibility and Requirements

Check Carrier Support: Verify that your mobile carrier supports WiFi calling. Most major carriers do, but it’s always best to confirm.
Update to the Latest iOS: Make sure your iPhone 15 is running the latest version of iOS. Go to Settings > General > Software Update to check for updates.
Connect to a WiFi Network: Ensure you’re connected to a stable and reliable WiFi network.

Step 2: Enable WiFi Calling in Settings

Open the Settings app on your iPhone 15.
Scroll down and tap on Phone.
Tap on WiFi Calling.
Toggle the WiFi Calling on This iPhone switch to the On position (green).
A pop-up may appear asking you to confirm your emergency address. Tap Update Emergency Address and follow the instructions to provide your current location. This is crucial for emergency services to locate you accurately if you make a 911 call over WiFi.

Step 3: Verify WiFi Calling is Active

Once enabled, you should see “WiFi” displayed in the status bar at the top of your screen when you’re connected to a WiFi network. This indicates that WiFi calling is active.

Step 4: Make a WiFi Call

Open the Phone app.
Dial the phone number you want to call.
Tap the Call button. Your iPhone will automatically use WiFi calling if it’s available.

Step 5: Troubleshooting Common Issues

WiFi Calling Not Available: If you don’t see the WiFi calling option in your settings, contact your carrier to ensure it’s enabled on your account.
Poor Call Quality: Ensure you have a strong and stable WiFi connection. Try moving closer to your router or restarting your router.
Emergency Address Issues: Make sure your emergency address is accurate and up-to-date. You can update it in Settings > Phone > WiFi Calling > Update Emergency Address.

Tips For Optimal WiFi Calling

Prioritize WiFi: When possible, connect to WiFi networks to conserve cellular data and improve call quality.
Monitor Battery Life: WiFi calling can consume more battery life than regular cellular calls. Keep an eye on your battery level and charge your phone as needed.
Use a Strong WiFi Signal: The stronger your WiFi signal, the better your call quality will be. Avoid making calls in areas with weak or unstable WiFi.
