That's great! I am just wondering about TEP covering the Nexus 6P. I was told that it would not cover the 6P by a few Sprint reps. Although, I have to admit, ditching the $11/mo for an upfront Nexus Care plan ($89) was nice as it'll more than pay for itself in the long run. Albeit you only get 2 device replacements per the plan and have to pay a moderate fee for the deductible, which isn't bad compared to TEP deductible.
I had a great amount of difficulty finding a SIM card for my 6p in my town. I was told that sprint retail locations do not carry the micro sim used by the 6p. Make sure you have made arrangements to have a sim shipped to you before your phone arrives, or you're in for a frustrating experience. I was also told that the SIM card for the HTC m9 will work for the 6p as well as the SIM card for the iPhone 6 or 6s. Have your local sprint store look up which SIM cards fit your 6p device.
all the info needed to see which sim card is needed is in the link i posted above.
