The PLS8 does not support VoLTE, voice over LTE. It falls back (CSFB) on 3G (or less) to send and receive voice calls. Which is fine since that's how most carriers work anyway: it seems very few actually support VoLTE.Voice Support (HR, FR, EFR, AMR narrowband & AMR wideband) (PLS8-US/-E)
Handsfree speaking (PLS8-US/-E)
Voice Support for LTE via CSFB (circuit-switched fallback) (PLS8-US/-E)
The PLS8-V, with only LTE support definitely cannot do voice for anyone, it is strictly LTE data only and not very useful.
