Last week, Microsoft announced its first flagship smartphones for quite a while now, the Windows 10 Mobile-based Lumia 950 and Lumia 950 XL. Although Microsoft did manage to draw some initial interest from potential customers in the US, the company will intentionally limit the availability of its phones in the US.

Just a few hours after Microsoft’s event ended, AT&T announced that it will sell the Microsoft Lumia 950 through its channels, with the announcement failing to mention any details about a possible exclusivity. As days passed, what followed was a mixture of reports, rumors, and unofficial statements from Microsoft executives regarding a possible exclusivity arrangement.

What this means is that the Lumia 950 will be carried exclusively by AT&T at launch, and that broader availability will probably follow at some point in the future. One interesting detail to note is that AT&T did not mention the Lumia 950 XL in its announcement, which probably means that the carrier will only offer the smaller Lumia 950.
