Default Need to Find Cellular (Voice) & Data Tablets

I've been trying to find a 10 inch (or so) Tablet, or Phablet, that has cell and data capabilities. Also, it seems that the cell companies, T-Mo, Att, etc.,
don't have a plan or will even provision one. I've seen a few on youtube and for sale at eBay and Amazon, but those are International units
and don't have 4g/LTE, and are pretty low spec.

I thought the Samsung Tab models came that way, but they don't. Is there a list or a thread that would help me?
