A player being able to deposit via their phone bill (PSMS) is important though not a particulary new development in the world of mobile content (think Crazy Frog,no dont) and gambling.Its a quick and easy method for the casual player to get cash in their account.
Mobile will not replace the online casino but it does give a player the flexibilty to play pretty much where they want.It then comes down to the user experience of each particular casino that will determine how much revenue an affiliate makes.Its Defintely worth playing a few casinos first to see which you consider to offer the best games,speed of play etc.
