"This move is a dream come true for me and I intend to make a big impression here at Wigan," he told the clubs official website.
"Obviously it's a wrench to leave Tranmere having started my career there. Everyone at Rovers has been brilliant to me and I wish them and Brian Little all the best for the future, they deserve success there.
"The chance to play in the Premiership at this stage of my career is almost unbelievable. Everyone in football wants to play in the Premier League and I'm no different, I'm just delighted it's happened for me."
