VoLTE: Make Calls and Use Data at the Same Time
VoLTE (Voice over LTE) allows both call and data services to be carried on the same 4G network, which
means you can use the Internet even while making calls. VoLTE also provides you with shorter call
connection times and higher quality voice and video calls.
Both of your Phone's SIM card slots support 4G, VoLTE, and VoWiFi, so there is no need to switch
SIMs back and forth.
l
Dual 4G: Both of your Phone's SIM card slots support 4G.
l
Dual VoLTE: Both of your Phone's SIM card slots support VoLTE, allowing you to use the Internet

l
Dual VoWiFi: Both of your Phone's SIM card slots support VoWiFi, which allows calls to be made
using Wi-Fi. You can use VoWiFi to make calls even in Airplane mode.
