Nielsen Mobile (formerly Telephia) provides market research and service quality data on the wireless telecommunications industry. It primarily serves more than 100 device makers, retailers, and service operators in the US, Canada, and Europe, providing insight into the competitive landscape and areas of customer needs. Nielsen Mobile measures such areas as subscriber share, network quality, device share, customer satisfaction, and application usage.

Nielsen acquired Telephia in 2007 to crack into the wireless telecommunications market research sector. With its vast network of resources, Nielsen significantly strengthened the former Telephia's product scope and broadened its geographic reach. Nielsen Mobile tracks various consumer behavior of mobile device users such as the purchase of games, music, and ring tones. It also measures share of mobile Internet, TV, and video audiences.
