The campaign was staged for a big Shopping Centre in the run up to Christmas last year. An interactive SMS campaign that enabled shoppers to decorate an interactive Christmas Tree in the centre was created.To take part, shoppers sent a free SMS to a shortcode with the name of a gift. There were 100 gifts to choose from, with each one lighting the corresponding gift on the Tree.In addition, everyone who texted in received a return SMS inviting them to visit the shopping centre’s mobile site to find out more about the campaign, download free content and send Christmas Voice Messages recorded by Santa Claus.
