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 does VoLTE work with Wi-Fi Calling?

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

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

When do I need to update my location information?

Does 9-1-1 work with Wi-Fi 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 Wi-Fi 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 Wi-Fi 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, Wi-Fi Calling will be disabled while your wireless device attempts to connect to a local wireless carrier network to route your emergency call.
