Is Microsoft refusing to send the Dual SIM Lumia 950 & Lumia 950 XL to T-Mobile for testing?

REDMOND, Wash. — By now, the Americans know that Microsoft’s Lumia 950 and Lumia 950 XL are dual SIM, which means they are not supported by any of the fifteen nationwide carriers in the States (Verizon, Page Plus, AT&T, Cricket, Sprint, Virgin, Boost, CREDO, T-Mobile, MetroPCS, Wal-Mart Family Mobile, SIMPLE Mobile, Tracfone, Straight Talk or Net10).

What that means that on GSM Networks, the phones will not have Voice on LTE or Voice Over Wi-Fi – not even on T-Mobile’s network.

Some would say that Big Pink is being sour grapes because Microsoft passed them over, but Google passed over T-Mob as well and their new Nexus line of phones are VoWi-Fi and VOLTE compatible.  Also, Acer will very likely give its Liquid Jade Primo (the first announced Windows 10 phone) the same compatibility as the Nexus 5X and 6P even though the Liquid Jade Primo is expected to be dual SIM, just like the Lumia flagships.

However, I still haven’t read where T-Mobile, located just seven miles from Microsoft in Bellevue, had received any of the five phones – the RM-1085 Lumia 950 XL, the RM-1116 Lumia 950 XL Dual SIM, the RM-1104 Lumia 950, the RM-1105 AT&T Lumia 950, or the RM-1118 Lumia 950 Dual SIM – for testing.

Which leads me to one of two questions.

The first is this: is Microsoft refusing to send their phones to their local Seattle-area carrier for testing?

Or the second: is T-Mobile just sour grapes after MSFT passed them over in round one of the #Windows10Devices?

I’m betting that it is the first, considering the fact that Microsoft still has these ambiguous links on their site:

Can I use Voice over LTE services with my Lumia?

Does my Lumia support VoWiFi?

With that said, though, I still have not seen – on social media or elsewhere – where the RM-1085 and RM-1104 models were tested on T-Mobile US’s network for VOLTE or VoWi-Fi.  However, given that United Kingdom carrier (before a firmware update) EE had both services, I am confident that the single SIM Lumia flagships will have VoLTE and VOWi-Fi, however, the same cannot be said of the US versions of the flagships.

However, the ball is in the court of the Seattle-area mobile corporations and their CEOs – Satya Nadella and John Legere – to sit down together like grown men, test the devices on T-Mobile’s network, and answer the questions that both Windows and T-Mobile fans alike want – and deserve – answers to.
