To clear up some stuff. Verizon is going to 5G and the "plan" is that in 3-5 years, disconnect the 3G network. All new phones will have 1 single antenna. Thus, you either need to be on a data/HD/VoLTE call (which since you are using data, you can just use more data for internet) or you use the antenna to make the call over the cell signal, 1x, and no data. Once we have all 5G and 4G is the "fall back" signal, there will be much less of an issue. Cell call quality is dramatically better on VoLTE. It sucks. but its the future.
