Yes, I am on 3G. I have thought about upgrading. But I have read so many conflicting comments about it. Some say it helps a lot. Some say no real change. From what I understand, the browser is so basic that the real issue is that Tesla needs to fix that. Posts below yours comment on this in this thread. I do live in an area with not the greatest cell reception, regardless of 3- or 4G, due to all the damn tree huggers who don't want more cell towers. Now, I am actually a tree hugger. But I also want decent reception where my calls aren't dropped every couple of miles!!!
