Ad-funded mobile MVNO Blyk will launch in Germany, Spain, and Belgium next year, the company said today. Reuters reports that British-Finnish start up is in “late stage” talks with operators over network renting in the three countries. According to Blyk co-founder and chairman Pekka Ala-Pietila Germany and Spain represent some of the continent’s largest ad markets, while Belgium’s ad-spending per capital was among Europe’s highest.

But the three countries are also home to some of the continent’s most competitive mobile markets. Germany’s market has been locked in a fierce price war for several years, spurred by budget carrier E-Plus. Spain is another tough market, already crowded with three main operators and dozens of MVNO’s competing on price.

Blyk, however, remains undeterred and promises these three countries won’t be their last. In the UK, the ad-funded MVNO has amassed 100,000 customers, who receive 217 texts and 43 minutes of voice calls each month for free, in return for receiving six promotional texts a day. According to the company’s unaudited figures, the ad campaigns have an average response rate of 29 percent.
