Quite right, poor choice of phrase on my part. My point was that there are people who are e.g. legitimately surprised when their high-speed data connection drops and it prevents them from using Google Maps on their smartphone. To them, it's functionally a GPS, not Internet-based at all. Similarly for certain messaging apps, which integrate with the phone's OS so tightly that it's not apparent that they're using Internet-based communication vs. SMS. My larger point was that to then expect all respondents to a phone survey (on a measurement significantly linked to technical literacy, no less) to make similar distinctions unprompted is perhaps a bit of reach.
