This past quarter, Sprint recorded a net plus in postpaid subscribers for the first time since the second quarter of 2007, as it added a net 58,000 to its postpaid rolls. The carrier also added a net 1.1 million wireless subscribers in all, although nearly half of those were prepaid wireless customers. This is important for Sprint because postpaid subscribers typically deliver average revenue per user (ARPU) nearly two times as large as prepaid subscribers. Last quarter, for instance, Sprint generated ARPU of $55 for postpaid subscribers and only $28 for prepaid subscribers.
