When we are traveling, we routinely use 15-20GB of data each (two people). Streaming music a reasonable amount (no streaming video), email, social media, blog updates, etc seem to take up a surprising amount! Those who are stationary with decent campground WiFi probably don?t need the same thing as those of us in the boonies far away from WiFi. Oh, and I have an Apple. I enjoy the seamless integration of their products, and iTunes is a wonderful invention LOL! I am happy with my unlimited Verizon on two lines. We haven?t ever hit the throttled amount, but we have come close a few times. They seem to have good service where we travel which is almost exclusively West with a few trips to the Midwest.
