It's also possible that the family could pay for a data plan for their kid to use but don't do it because they don't believe their middle school kid needs a data plan. Another possibility the users could have a data plan but prefer not to use it/ are out of data for the month. My much younger siblings on my father's plan are limited to a portion of the data plan (enforced by verizon plan options) and once they go over that they can't get data anymore.
