AT&T customers with the new iPhone 6S and 6S Plus, as well as last year's iPhone 6 and 6 Plus, can now make calls over Wi-Fi.
The Lumia 950 and Lumia 950 XL, which arrive in November, are headed down a sales path that has largely fallen out of favor.
The carriers will use their sections at Best Buy to better promote their smartphones, tablets and various services.
One number to rule them all: AT&T's latest service uses your digits across multiple connected devices.
That's the only way they'll solve real problems, says Glenn Lurie, speaking at the Code Mobile conference. He also notes that the iPhone 6S has sold well.
Verizon Wireless, T-Mobile and Sprint are expected pass on the Lumia 950 and Lumia 950 XL in the United States.
The FCC is dragging its feet on granting AT&T a waiver to offer a Wi-Fi calling feature, while letting competitors go ahead, says the company. The feature fails to meet accessibility rules for the disabled.
AT&T customers, rejoice; Wi-Fi calling is available on your iPhone with iOS 9. Here's how to enable it.
The 10.1-inch tablet will be the first to come preloaded with the DirecTV Everywhere app, providing access to live television broadcasts.
It marks the first time a company has been able to offer a bundle of television and wireless service throughout the nation.
