Supplies of Microsoft's Lumia line of handsets are dwindling across the board. It started a couple weeks ago, when Microsoft removed the Lumia 650 and 735 listings from its online Store. Next to go was the AT&T-locked Lumia 640 XL, and then Cricket Wireless took down its listing for the Lumia 650.
AT&T suddenly went out of stock on all variants of the Lumia 950 nine days ago, but then it removed the listing for the white model, and the black model was in stock again. Well, the carrier is once again out of stock.
The only official channel that you can use to get an AT&T-locked Lumia 950 right now is the Microsoft Store, which is only selling the white variant. Sadly, the unlocked model is sold out, despite being in stock just five days ago.
The Lumia line of Windows handsets is clearly coming to an end soon. The Lumia 650 is the newest model, turning a year old in a few weeks, and that has been removed from both the Microsoft Store and Cricket Wireless.
For now, there are only a few first-party places that you can go for one. The Microsoft Store still has the Lumia 550 and AT&T Lumia 950, Cricket is still selling the Lumia 640 and Nokia Lumia 635, and Verizon is still offering the Lumia 735 on its website.
