Google Nexus 6 :: LTE Turns Off When WiFi Is On?

their N6 on Sprint where Sprint service essentially turns off whenever Wi-Fi is on. This is the only way I've been able to describe my issues with the N6. Whenever I am at home, I am usually on Wi-Fi because it works more reliably than LTE. So whenever someone calls me, the call goes straight to voicemail. I only receive a missed call notification if someone leaves a voicemail. I've been able to test this out with family members where I turn on Wi-Fi, they call me, and the call goes straight to VM. Then, I turn off Wi-Fi, they call me again, and I get the call.

Keeping LTE on all the time (and Wi-Fi off) would not be an issue but for the fact that Sprint's service notoriously sucks inside any building made of concrete (even in Manhattan). I'm not ready to switch providers because I've been grandfathered into a no-throttle unlimited everything plan where I essentially can use 5GB of data each month and pay a reasonable price. I moved to NYC recently and before lived in the D.C. area, where I lived in a house adjacent to a tower. There, I didn't mind keeping Wi-Fi off because I always had great LTE.

This is quite frustrating and it appears to be documented to some effect on Sprint's website (without a fix, of course). Sprint has now reset my network, PRL, and profile; and the only other option appears to be replacing the phone through my insurance. I'm hesitant, though, because I preordered a 6P.
