(279,9 CZK, 0,25%) announced a CZK 749/month flat-rate calling plan, including unlimited SMSes and 1GB of data per month. Without a two-year contract, the rate rises by CZK 150. O2 also has a new flat rate of CZK 249/month for calls and SMSes within its own network. (2,2 EUR, 0,00%) responded by announcing plans for a flat-rate calling program in May for less than CZK 700/month. It will include 600MB of data. /O2’s new tariff is to 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 (that has not been visible in czech retail market so far) and this step should lead to lower margins and EBITDA as all the current operators will most probably to follow such a lowering of prices. Slightly NEGATIVE.
