SO I ordered a bunch of iPhone 6's and 6+'s for work. We received a few of both versions on release day. I had read there was an option to enable DATA AND VOICE by going to Settings>Cellular. I did this on those phones. Fast forward to yesterday when I received my 6+, did the 8.0.2 update and went to do the same on mine and it is not there now, just a slider for ENABLE LTE. So I grabbed one of the phones that I did it to last week, and theirs still has the option. Was it removed in the last minor update? See below (first his, then mine).
