This question is required in order to send SMS (text) messages. We require this question because, though rare, some volunteers may be charged by their phone provider per text message they send or receive. Other volunteers may simply not like to receive text messages.
If a volunteer opts in to this question, they receive texts sent either by an administrator or automatically through an event (if enabled).
If this question is deleted, all options to send text messages through VolunteerHub are removed.
