What is VoLTE?

VoLTE (Voice over LTE) is the next generation of voice service for your phone.

VoLTE will provide superior voice quality and allow you to browse the Internet and use data-driven apps while on a call. VoLTE must be enabled on your device to experience these new benefits and our 5G network where available. Simply put: talk and surf at the same time!

When do I need to update my location information?

You should verify and update the Registered Location information regularly. Be sure to update your registered address each time when accessing a WiFi network with the same name (SSID) that may exist in multiple locations.

Does 9-1-1 work with WiFi Calling?

Yes. A 9-1-1 call may first attempt to route over a wireless carrier network. If a 9-1-1 call doesn't route over a wireless carrier network within approximately 20 seconds, a 9-1-1 call may then attempt to route over WiFi Calling. Always be prepared to provide your precise location information to emergency service personnel and to contact emergency services by alternate means.

International locations: Emergency calling is not supported over WiFi Calling outside of the domestic United States. However, your wireless device may be able to connect to local emergency responders abroad over a local wireless carrier network using GSM or CDMA by dialing the appropriate abbreviated dialing code in that area, such as 1-1-2. If you attempt such a call, WiFi Calling will be disabled while your wireless device attempts to connect to a local wireless carrier network to route your emergency call.

How does VoLTE work with WiFi Calling?

WiFi Calls will transfer to VoLTE when WiFi coverage becomes poor and VoLTE is available. For this automated transfer to take place, VoLTE must be turned “ON” on your device.

Conversely, if WiFi Calling is turned “ON”, calls can transfer from VoLTE to WiFi when the device is connected to a strong WiFi signal capable of supporting a call over WiFi.
