My current cell phone plan includes 200 minutes, and free calling at night (from 6PM to 7AM) and on weekends. Is there a term in the mobile industry to mean the minutes used during time other than weekends or nights? Is "airtime" exactly for that purpose? Similarly, what is the term for used minutes during weekends and nights?
For example, in my latest bill, I used 30 minutes at nights and weekends, and 108 minutes during times other than nights and weekends. Since 108 is less than 200, I don't have to pay extra money other than my basic plan fee. If I had used more than 200 mins during other times, I would have had to pay additional fees for the extra minutes.
