6s Cellular Data Usage not counting

[wchangch]

Since my 6s arrived yesterday I've noticed my Cellular Data Usage not counting at all and stays at 0 kb. Has anyone one seen the same issue? I made sure the wifi was turned off and I was surfing and also watched a couple of YouTube clips on LTE, but it still stays at 0. Could this be hardware, iOS bug, or just my new 6s being defective? I'm running iOS 9.0.1 on 6s, T Mobile. Thanks!

Ya that would suck if it were not counting how much data you are using.
Better sell that phone to me.
