Nokia Lumia 830 and HTC One (M8) for Windows arrive at AT&T on November 7

AT&T today confirmed that it would launch two new Windows Phone 8.1 handsets later this week, on November 7: the Nokia Lumia 830 and the HTC One (M8) for Windows.

Already available to buy unlocked in the US, the Lumia 830 will be offered by AT&T for $99.99 on contract, $449.99 off-contract, or for free on an AT&T Next plan (in this case, you’ll have to pay $18.75 a month with Next 18, or $22.50 a month with Next 12).

The 830 is the thinnest Lumia smartphone ever, and it’s among the last Windows Phone handsets to bear the Nokia brand. Its features include a 5-inch IPS display with 720 x 1280 pixels, a 10 MP PureView rear camera, quad-core Snapdragon 400 processor, 1 GB of RAM, and 16 GB of expandable internal memory. For a limited time, AT&T will offer a free Fitbit Flex fitness tracking wristband to customers who are buying the Lumia 830.

The HTC One (M8) for Windows will be more expensive than the Lumia smartphone: AT&T will sell it for $199.99 on contract, or $669.99 off-contract. To get it for $0 down, you’ll have to pay $27.92 a month with AT&T Next 18, or $33.60 a month with AT&T Next 12. Verizon is already selling the One (M8) for Windows - which, except for the fact that it runs Windows Phone 8.1, is similar to the HTC One (M8) that runs Android.

Another new smartphone that will be available at AT&T starting November 7 is the Android-based HTC Desire EYE - this features a 13 MP front-facing camera and a 13 MP rear camera, and will cost $149.99 on contract.
