VoLTE stands for “voice over LTE.” What it means is that, when you make a call, your voice goes over your carrier’s high-speed data network instead of its voice network.
Big advantages:
First, better sound quality — if you and your calling partner both have VoLTE and VoLTE-compatible phones. In today’s “Ask Pogue” video, I conducted a rock-solid experiment, so that you can hear the difference. (The improved quality is what the carriers are calling HD Voice.)
Second, your call connects faster after you’ve dialed.
Third, there’s no more big difference between the two competing cellphone networks in this country: CDMA and GSM. Verizon and Sprint have CDMA; AT&T and T-Mobile have GSM.
Fourth, if you have Verizon or Sprint, right now you can’t be on the phone and on the Internet at the same time. Once you’re on VoLTE, you’ll be able to.
Right now, only two networks have VoLTE nationwide: T-Mobile and Verizon.
