The new flat rates have attracted tens of thousands of people so far. O2 launched an ad campaign yesterday that will be more expensive than the 70m CZK it has spent on its Christmas campaigns. O2 also said that it will meet with companies on an individual basis in the coming weeks and months. (2,22 EUR, -0,09%) said that it will announce new calling programs in mid-May for self-employed people. GTS plans to launch rates as a virtual mobile operator this summer, working with T-Mobile, that are competitive with the new flat rates. / We expect continuing „price-war“ of operators during coming weeks/month. New tariffs may make it harder for PPF or any other fourth operator to enter the mobile market, but on the other hand it is a sign of a price competition and this step should lead to lower margins and EBITDA, consequently lower dividends in the future.
