The rumored Nokia Lumia 830 has made the news again, this time with claims that it will be exclusively available from AT&T in the U.S.

The rumor mill has been buzzing recently in regards to a new Nokia Lumia 830 that may make its debut soon, and now a new report claims that AT&T grabbed the exclusive on this upcoming handset.

As the name itself suggests, the Nokia Lumia 830 will arrive as the successor to the Nokia Lumia 820 that launched back in November 2012 as a mid-range Windows Phone offering. Its successor is expected to come with mid-range specs as well, but should nonetheless pack some notable improvements.

According to a new report from Neowin, citing "a reliable source," a new smartphone with the codename "Train" will make its way to AT&T's network sometime this year. Not too long ago, some leaked images surfaced online allegedly showing the upcoming Nokia Lumia 830, and it is now believed that it is one and the same with this purported AT&T "Train" smartphone.

Adding a new Windows Phone exclusive to its portfolio would make sense for AT&T, especially since other neat exclusives are on the horizon for its rivals. More specifically, Verizon is rumored to be getting the Windows Phone version of the popular HTC One M8. If this turns out to be accurate and Big Red will be the only one to sell the One M8 for Windows, AT&T will need some big guns to stay competitive in the Windows Phone space.

The Nokia Lumia 830 may not boast the high-end specs and features of the HTC One M8 for Windows, but its mid-range specifications should allow for an affordable price tag. It remains unclear at this point just what specs it will have to offer, but its predecessor did a pretty good job in the mid-range department.

As a reminder, the Nokia Lumia 820 launched with a 4.3-inch AMOLED display with a 800 x 480 resolution, a 1.5GHz dual-core Snapdragon S4 processor, 1GB of RAM, and 8GB of internal storage capacity, expandable up to 64GB via MicroSD. Other specs of the Lumia 820 include an 8-megapixel rear camera with auto focus and a VGA front shooter, as well as a decent 1,650 mAh battery. Its successor, the Nokia Lumia 830, is expected to boast some upgraded specifications, but little is known so far in this regards. On the software side, the handset should launch rocking the very latest Windows Phone 8.1 version out of the box.
