Adoption of non-text mobile data services has exceeded 40% of the more than 70 million U.S. broadband households with a mobile phone service, according to Parks Associates’ new consumer study Mobile Convergence: Platforms, Applications, and Services.

Over one-fourth of mobile service users have adopted mobile Internet and e-mail services, eclipsing other mobile data ARPU drivers like mobile TV and music, indicating that carriers will have to win subscribers through more “practical” services first. The fast adoption of mobile social networking and navigation services, which have both exceeded 10%, also indicates carriers can be successful in deploying popular Web activities as revenue-generating data services on the mobile platform.

Non-text mobile data services are central to wireless carriers’ long-term plans for revenue growth. The strong growth in usage of mobile Internet, e-mail, social networking, and navigation during the past two years shows consumers are eager for mobile applications that offer convenience and rich features. Use of multipurpose devices like smartphones is another driver. Smartphone penetration will exceed 30% of broadband households in 2009. These 20 million households will be a perfect target for carriers to market their mobile data services.
