The Big Red has quietly debuted its Voice over LTE (VoLTE) service for its prepaid customers. Verizon Wireless is branding the service as HD Voice, and basically it allows prepaid customers of the biggest mobile operator in the United States to utilize data while on a voice call, to complete one or two way video calls, and to enjoy access to to six way conference calls. Verizon’s HD Voice promises better audio reception and is capable of being accessed over Wi-Fi calling.
Prepaid customers of Verizon Wireless who currently mobile devices enabled with VoLTE can now incorporate the HD Voice service to their accounts by way of their My Verizon portal, absolutely free of charge. With regards to billing, calls are charged per minute, similar to how standard calls are billed.
In order to successfully make VoLTE calls, both the devices of the caller and the recipient of the call must have the HD Voice service activated. Moreover, the feature will need LTE connections on both ends to work. However, it bears noting that there are a number of VoLTE enabled handsets that do not have support for video calling. As for Wi-Fi calling, it only works if the device being used has support for this kind of wireless tech.
One advantage of VoLTE technology is that it has the ability to deliver triple the voice and data capacity compared to current 3G technologies. The result is an improved quality overall in terms of call connections. Furthermore, VoLTE technology also lets various mobile operators to expand their bandwidth.
Among today’s providers, major US wireless carrier T-Mobile appears to be the more aggressive in taking full advantage of VoLTE technology. As a matter of fact, the wireless carrier routes more than half of all its voice call minutes via VoLTE. Industry leaders Verizon Wireless and AT&T are currently in the midst of deploying their respective VoLTE offerings. Earlier this year, both operators started making VoLTE widely available. The original plan was to kick things off before the start of 2016, but some significant progress has been made this year. Back in December of last year, AT&T completed its first VoLTE calls between its subscribers and another wireless carrier.
As for Sprint, the fourth biggest wireless carrier in the US has decided to put most of its attention to other technologies such as carrier aggregation and beamforming.
