From today (15 February), the mobile giant is ramping up its Top-up Surprises programme by guaranteeing every customer a 'gold' surprise until 31 March.
Gold surprises include the chance to be a popstar for the day with Rihanna or fly on the official Arsenal plane to a 2010/2011 season Uefa game, for a limited period.
Using the new strapline 'We've upped the game' the campaign will again feature the signature yellow ducks but makes them twice the size. The drive will initially break tomorrow with a TV ad during the Brits and will be followed by print and online activity.
An online game called 'Quacky Races' will also be launched to engage potential customers who choose a duck character and then race it around the world. The player who gets there in the fastest time wins an around the world trip.
O2 Top-up Surprises launched in November 2008 and includes free texts, picture messages and minutes through to race days and a car.
The site attracts more than 2.4 million every month according to O2.
