Soft drink brand Appletiser has launched this month in the UK an on-pack promotion to drive sales and engage consumers in a mobile relationship. Steam and Netsize have created a text to win competition which allows entrants to win diamond jewellery every day for 3 months. All entries then go into the main draw to win £50,000 worth of diamond jewellery designed by Tom McEwan. An online quiz is also part of the effort.
