Question regarding Galaxy S7 Edge (Exynos) Unlocked on T-Mobile in the US

[AC Question]

Hello, AC. I am currently considering purchasing a Galaxy S7 Edge (Exynos) unlocked for use on T-Mobile USA. I see that all the bands are supported here on the US, but I'm still worried about how well the phone works on T-Mobile. I recently heard that T-Mobile will block any devices without their own (T-Mo's) VoLTE certification from accessing LTE band 12 outright. Can anyone confirm if this is true? I would hate to purchase this phone and then find out I can't use it on band 12.
I would really appreciate if someone could clear this up for me. Thank you for your time.

Hi, can you please create an account and head on over to our S7 edge forum - I'm sure there will be plenty of people who will be able to assist.

Have you spoken to T-Mobile about this, maybe they could confirm to you?
