If you go to Microsoft Lumia 950 Specifications - Microsoft - USA on microsoft.com, it now lists Band 13 (700 MHz) as supported. This is the band that requires Verizon to allow the phone on it's system per FCC regulations and pending network certification. We need to start hitting up Verizon and Microsoft to see what's up.
I would point out that if you look at the specs listed at the Microsoft Store webpage, Band 13 is not listed. Is it a typo?
