Phonevalley, the mobile marketing agency owned by Publicis Groupe, says that it has opened offices in Singapore, China and India to be able to offer regional brands and advertisers local mobile campaigns, according to cellular-news.com. Devashish Sarkar will be Phonevalley’s Regional Director for the APAC region.
