Hello all. I have a question about FaceTime. I have an iPhone 4 and we recently purchased an iPad 2 for my mom. My mom thought it would be cool to be able to do a FaceTime call from her iPad to my iPhone, say, if she's in the basement and I'm upstairs in my room, and we could talk to each other if she needed something (one of those totally unnecessary but cool things . The problem is, we have satellite Internet which is terribly slow and has a very low download limit accompanied by a terrible latency. So, video calling from our house to an outside network is out of the question for those reasons. My question is, if we were to do FaceTime calls only on our home network, would that still use up data towards our monthly limit? I did a test call for just a few seconds, and the latency was not there; the call seemed to be in real time. So if it doesn't use up our monthly download/upload limits, then I think we should be good to go. Any thoughts?
