Uncomplicated mobile calls at border-busting prices: That’s the simple message from yallo – an affiliated brand from Sunrise – which is directed particularly at customers in Switzerland who also want to make international calls cheaply from their mobile telephone.

Four years following the launch of the yallo brand, the company has become very popular with mobile phone users in many European countries thanks to its flat rate of 25 centimes per minute. yallo also launched its new yallo subscription service on 8 June 2009. With this unprecedented offer in Switzerland, mobile phone calls to fixed networks in six European countries cost merely 10 centimes per minute.
