Following the introduction of Voice-over-LTE technology with the iPhone 6 and 6 Plus, which increases call quality by routing calls through an LTE network opposed to last generation 3G networks, US carriers have experienced a big increase in VoLTE calls. That’s according to a new report from Newfield Wireless that highlights a decrease for calls over 3G by about one-fifth compared to previous generation iPhones and other LTE-capable devices:

The majority of voice calls made on other 4G-enabled devices are currently routed through legacy 2G and 3G networks, due to the fact that not all networks and devices are optimised to deliver next-generation voice services. iPhone 6 devices are VoLTE-compatible and as a result, U.S. networks have experienced a surge in VoLTE calls since the September launch.

The report also shared some other data points from its research noting a few stats for iPhone 6 and 6 Plus uptake compared to previous generations:

Apple has announced several new wireless features for the iPhone 6 and iPhone 6 Plus, including faster Wi-Fi that achieves speeds of up to 3x faster than previous models. New LTE technology is also preset, allowing speeds of up to 150 Mbps.

Perhaps more importantly, Voice over LTE calling has been enabled, and can take advantage of the new Wi-Fi hardware to place calls over a Wi-Fi connection while still using your cellular phone number. T-Mobile is one of the first carriers rolling this out in the United States.

The iPhone 6 will operate on over 200 carriers on 20 different LTE bands.

Verizon Wireless has announced its plans to launch support for Voice over LTE service (or VoLTE) on its cellular network later this year, according to FierceWireless. However, the company says it has moved back its plan to release a VoLTE-only phone until 2016, and will continue releasing CDMA-capable phones until that time. Such a device was originally anticipated for the end of 2014.

The carrier originally announced earlier this year that it would support the new voice service, which provides higher-quality phone calls by utilizing high-speed data connections, but declined at the time to say exactly when it would happen. Other U.S. carriers, including T-Mobile and AT&T, have already started rolling the technology out in select markets.

Following announcements earlier this month from both AT&T and Verizon, T-Mobile announced today it’s introducing Voice over LTE support starting with the Seattle market:

So I’m thrilled to congratulate my team on the launch of Voice over LTE (VoLTE) in the Seattle area for our existing LG G Flex and Samsung Galaxy Note 3 and Galaxy Light customers. Our friends at MetroPCS were the first to launch VoLTE in the U.S. back in 2012, and we’ve been working hard on a LTE Advanced version of VoLTE, which we plan to roll out to more T-Mobile customers throughout the coming year.

T-Mobile’s CTO Neville Ray noted that the new technology, which brings voice calls onto the same LTE radio layer previously reserved for data, will allow “faster call setup times (almost twice as fast as a non-VoLTE call setup) and the ability to enjoy lightening fast LTE data speeds while on a call.” It will also support the HD Voice or wide-band audio feature that Apple already supports. Ray explained how the technology works:

Verizon Wireless is officially joining in on this year’s major new cellular network technology: Voice over LTE, or “VoLTE.” VoLTE allows voice calls on compatible smartphones to be made over the previously-data only LTE network technology. This allows for higher-quality, better sounding (“HD Voice”) phone calls to be placed. The rollout will occur “later this year”, or “in the coming months” depending on which part of the press release you believe:
