Hello. My dad is a Verizon customer and I'm considering switching him to TMobile for the iPhone5. What I would like to do is get him on an unlimited plan and tether an iPad. He does not have an internet connection in his home. He is not technically inclined so I'm trying to stay away from buying a laptop and home internet connection. The thing he would use this set up the most for would be viewing pictures/video I send him and doing video calls - either FaceTime or Skype. 1. Can he tether the iPad? Is there an additional charge? 2. If he can tether, can he take advantage of the unlimited data? 3. If the iPad is tethered, could he make FaceTime calls from it?
