1. Restart your device and confirm active account status, an enabled SIM/eSIM and a compatible, carrier-unlocked phone. Wi-Fi calling must be supported and enabled for your line; do not assume every phone supports it.
2. Connect to reliable Wi-Fi and enable Wi-Fi calling in the device’s phone or cellular settings if available. Menu names vary.
3. Keep the registered emergency address current. Contact Customer Service to confirm or update it; do not guess an address.
4. If calls fail, try another trusted Wi-Fi network and check service notices. Contact Customer Service if the setting is missing or cannot be enabled.
5. For emergencies, dial 911 directly. Always be ready to state your location. Wi-Fi calling and emergency location have limitations; do not use website support for an emergency.
