Wi-Fi Calling and Voice over LTE

Phones are now coming equipped with a feature called Voice over LTE or VoLTE for short. This feature uses the LTE signal to send and receive calls, whereas before this feature, calls would use the 3G signal. 

The benefits of this feature are

  • Improved call clarity
  • Being able to use data while on a call
  • Place and connect a call faster

Another major benefit of using VoLTE is that a call will not drop if you disconnect from a Wi-Fi signal should you have Wi-Fi Calling enabled. In the past, when you started a call on a Wi-Fi network, the call would drop when you left the range of that Wi-Fi network. Now, because the call would be using the data signal of Wi-Fi to place the call, VoLTE offers the ability to utilize the data signal of the cell network to continue the call.

Note: This feature is only available on the GSM network at this time. Furthermore, the use of this feature depends on whether or not your device supports this feature. Not all phones are able to use VoLTE (sometimes called HD Voice). For more information on which devices are compatible, you can check question ten in this article.
