I am able to use the hotspot function on my iPad Air on T-Mobile's FREE 200mb/mo plan. I've read that this shouldn't be the case, and I called them and asked about it and they said hotspots aren't included in the plan, but it might be the case that my device will allow it. So I'm just confused... can I use it without incurring additional fees or penalties? If my plan shouldn't be allowing it, but my device does it doesn't make sense to me the T-Mobile would just shrug that off without adding some sort of fee. Similar question about the "Free International Roaming" that T-mobile plans are sporting. I've read that this applies only to phones and not tablets, but I've also read conflicting stories. So my question is first, will I be charged an additional rate/fee for using my iPad's data overseas? And then if so, would buying any of the available domestic plans allow me the free Int'l Roaming? There are daily and weekly plans as well as the monthly recurring ones... will any of those do? Or will I need to buy a specific international roaming plan while I'm away?
