Telefonica Digital announced operator billing support for apps bought from Google’s Play Store, RIM’s BlackBerry App World, and Microsoft’s Windows Phone Marketplace, enabling it to offer subscribers seamless payment for content.

In addition, it said that the deals with Google and Microsoft will allow it to create dedicated “stores within stores” for its various operating markets, as part of the Play Store and Marketplace respectively.

Telefonica Digital has also inked a deal with Facebook, to offer operator billing for virtual or digital goods purchased via the social network.

In a statement issued today, the operator group said that it is starting to rollout the capabilities in Europe, with plans to go live in “14 of its operating businesses globally by year-end.”

Telefonica noted that while more than one third of European smartphone users have paid for apps via operator billing, there is also a “particularly significant” opportunity in Latin America, where 60 percent of the population does not have a credit card.
