Like HD Voice, Voice-over LTE (VoLTE) and a host of other pioneering wireless innovations, T-Mobile has also long led the way with Wi-Fi Calling. Back in 2007, we were the very first US wireless provider to enable Wi-Fi Calling nationwide on our smartphones.

Now -- with the news coming out of Apple’s keynote today that Wi-Fi Calling will be enabled with iOS 8 – I’m excited to welcome our iPhone customers to the convenience and ease of T-Mobile Wi-Fi Calling as well.

When that happens, over 90 percent of all T-Mobile smartphones will feature Wi-Fi Calling.

Already today, T-Mobile provides Wi-Fi Calling capabilities to far more customers than any other major U.S. wireless provider. Already, there are 17 million Wi-Fi Calling-enabled customer devices on our network. Already, nearly 5 million customers use Wi-Fi Calling during any given month. And, these numbers are growing by the day.

Since we launched Wi-Fi Calling over seven years ago, our engineers have continued to deliver quality and user experience enhancements. As a result, our service is one of the most advanced natively-integrated Wi-Fi Calling products in the U.S. We have the deep technical knowledge and the close partnerships with device manufacturers to deliver the Wi-Fi call quality wireless consumers have come to expect from the Un-carrier.

One of the best things about T-Mobile Wi-Fi Calling is that it’s so simple to use. You don’t need to activate anything or download a special app. Just connect to any available Wi-Fi network, check that Wi-Fi Calling is turned on on your capable smartphone, and make a call (or send a text, email, etc.) as you normally would. That’s it.

And, like I said, we’ve been innovating on behalf of wireless customers in a bunch of other exciting ways as well.

In January 2013, we were the first U.S. carrier to roll out nationwide HD Voice more than a year ahead of the competition, marking a big step forward in dramatically enhancing in-call audio performance on many of the latest smartphones. With HD Voice, you hear a far more true-to-life voice quality that’s much fuller and more natural-sounding – and with a lot less background noise from street traffic, wind or crowd noise.

T-Mobile currently carries over 30 HD Voice-capable devices and – to date – T-Mobile customers have made over 5 billion HD Voice calls and have enjoyed over 12 billion minutes of HD Voice since launch.

We also recently launched Voice over LTE (VoLTE) in Seattle, a big, important step toward a host of rich communication services and additional innovations around Wi-Fi Calling that we’re looking to deliver to our customers over the coming months.

This is just the beginning. Stay tuned for what’s to come!
