SVLTE
Simultaneous Voice and LTE (Long Term Evolution)
A transitional standard that allowed a phone to simultaneously use a CDMA network for voice and a 4G LTE network for data.
Not all CDMA/LTE phones supported SVLTE.
SVLTE was only designed for 4G LTE networks. A different but related standard — SVDO — applied to 3G CDMA EV-DO data networks.

SVLTE was important because 4G LTE networks were initially only built to handle data, not voice. Without SVLTE, the LTE data network is unavailable during a CDMA voice call.
SVLTE was replaced by VoLTE (voice over LTE), which allowed both voice and data to operate on the LTE network.
