Kajeet, a provider of pay-as-you-go cell phone and wireless service geared toward tweens, has team with Nickelodeon to serve kid audiences through wireless content, reports MediaBuyerPlanner. Nickelodeon is the first kid content provider for Kajeet cell phones.

As part of the joint initiative, the Kajeet service will offer customers mobile content from Nickelodeon, including ringtones, wallpapers and games. Kajeet will also sponsor several Nickelodeon television events, starting with the upcoming new SpongeBob SquarePants Friend or Foe episode.

More than one in four U.S. tweens owns a cell phone, and that number is expected to double in the next three years, according to Kajeet.

"Like Nickelodeon, Kajeet is totally kid-centric and was created to bring together the world of communication, information and entertainment that today's technologically agile kids want in the palms of their hands," Daniel Neal, Kajeet founder and CEO said in a statement.
