Q: Some of us in the boonies must rely entirely on cellular Wi-Fi hot spots. As a result, data usage is a very important consideration, as each gigabyte must be paid for. Fortunately, we have 4G speed, but how much data do services like Instagram or Spotify use? How can one tell how much a YouTube video will consume? Obviously, one can go to a free Wi-Fi locale to see some content, but there are the security issues.
