Airtime is the time of a mobile connection during which usage costs are incurred. During this time, a mobile network operator makes a radio channel available to the customer for the transmission of his call or user data. The costs incurred for radio channel occupancy and radio network usage generally depend on the duration of the connection and the time of day.
In addition, the time that an airtime reseller purchases from the network operator is also referred to as airtime. A calculation model that differs from the airtime concept is that of the flat rate.
