Virgin Mobile USA entered the US market in 2002 through a joint venture with Sprint. It aimed to target the underserved youth market aged 15-29. Virgin launched an innovative prepaid service plan without contracts or hidden fees. Customers could buy minutes in advance and recharge their phones flexibly. This differentiated Virgin and allowed lower prices. Virgin's analysis showed its prepaid model could break even faster than competitors' regular plans. Its focus on extras and entertainment also appealed to youth preferences.
