The Greek mobile market where only 3 mobile network operators (3-MNOs) are present, was once again, ranked as the most expensive mobile market in EU and as one of the most expensive markets in the world. Even after excluding the mobile telephony tax Greek minimum monthly prices of smartphone plans with 1, 3 or 5 gigabytes were the highest in EU. And while telecom regulators in EU’s remaining 3-MNO tight oligopoly markets are taking steps to remedy effective competition – see recent 4th MNO entry in Portugal and ANACOM’s social tariff (30 gigabytes for 6 EUR) decision – the Greek telecom regulator EETT is in denial and has done little to remedy the apparent market failures in Greece.
