Does the iPhone 6s support LTE Band 12?

The specs posted on Apple.com show that the iPhone 6s does NOT support Band 12. I am a T-Mobile customer, and Band 12 is their main solution to solve coverage issues in rural areas and inside urban buildings.

I am ready to upgrade all of my iPhone 5s phones on 9/12, but ONLY if the iPhone 6s supports Band 12.

Tell me this is NOT so!!!!
