We want to provide our customers with the best experience at the lowest cost. Boost phones let you talk on the Boost network while also using data on a Wi-Fi connection.
This phone configuration provides the best battery life and the highest LTE data speeds at the lowest cost to you.
We apologize for the inconvenience.
Best option I have found since Sprint/Boost has not fully deployed Voice Over LTE (VoLTE) is that I use Google Hangouts (Google Voice) for outbound calling... this forces the call to go over a data connection (WiFi or LTE) thereby preserving your ability to use data at the same time as you talk.
