Orange will now include the channels as part of the Orange World sports package, which already contains programmes from Sky Sports.
The deal means subscribers can now watch every televised Premiership game live on their mobiles. Setanta will also screen matches from the SPL and Blue Square Premier, as well as a variety of other sports including golf and rugby league.
The Orange World Setanta sports package costs £5 per month and is available to customers with 3G handsets.
Orange head of sports partnerships and services Steve Wallage said: “The addition of the Setanta Sports package to our existing football portfolio was essential to ensure our customers didn’t miss any of this season’s action – we’re now the true home for football on your mobile.”
