What is VoLTE and WiFi Calling?


What is VoLTE?

VoLTE (Voice over LTE) is the next generation of voice service for your phone. VoLTE will direct your voice calls over to Boost’s newly advanced LTE network instead of our standard wireless voice network. 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!


How do I turn on VoLTE?

VoLTE is a simple toggle switch in Settings. To Enable, Go to Settings > Connections > Mobile Networks. Set the VoLTE toggle to On.


What are the other Benefits of VoLTE?

Make a voice call and surf the web at the same time. Enjoy superior voice quality for enhanced clarity.


Is VoLTE available in Roaming areas?

VoLTE calling may be available in select Roaming areas.


What is WiFi Calling?

WiFi Calling is a service that allows you to make and receive phone calls over a WiFi connection. It's simple to use with no separate application or log-in required. WiFi calling is a free service when calling to a US, US Virgin Islands, or Puerto Rico number. International rates still apply for international numbers.


What is the advantage of WiFi Calling?

WiFi Calling provides the ability to call or message from almost anywhere when a WiFi connection is available. The service provides enhanced coverage in locations that have limited or no mobile network coverage. With WiFi Calling, you can use the internet and apps while on an active call.


Is WiFi Calling available on all devices?

WiFi Calling is only available on the Nationwide Network and not on the Expanded Data Network.


How do I activate/setup WiFi Calling?

WiFi Calling is enabled in Settings.

Android Phones: Go to Settings > Connections > WiFi Calling

WiFi Calling will prompt you to enter a registered location prior to the service being used. This information may be used to route a 9-1-1 call to emergency services personnel.


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.


Will WiFi Calling support in-call handover between WiFi and wireless networks?

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”.
