So I'm just a bit confused on something. There is a 2013 wii only and I guess one with LTE that takes a sim card. You can attached a number to this tablet and receive text messages but not phone call, or so it would seem. Groove ip allows calls with the number attached but its not a real cell radio call. So what does this LTE version do that the wifi does not? Seems like the only advantage is to receive text messages.
