Orange will launch a multimillion-pound advertising campaign across radio, TV and print media to raise awareness of the prepay animals on 17 May.
Dolphin is designed for social networkers, offering free mobile access to Facebook, Bebo and Myspace, which reflects the changes in the way people use their phones. It also offers unlimited free texts to any network at any time when customers spend over £30 per month.
Canary offers free evening and weekend calls to any network and landline, and Racoon gives customers a flat rate of 15p calls to any network, any time.
Camel, meanwhile, allows customers to call over 50 countries from as little as 5p per minute, and the tariff gives customers the best rates to countries where Orange
operates such as France, Spain, Poland and Romania.
