Cosmote’s 4G network will be available in northern Bucharest, Otopeni, in the cities of Ploiesti, Cluj, Iasi and in mountain resorts Sinaia, Busteni and Predeal.

The new 4G network allows customers to download and upload data, at first, via two modems, Huawei E3276 and ZTE MF823, respectively, and via the Samsung Galaxy Note LTE 10.1 tablet, which may be purchased along with the Connect XXL two-year subscription, the operator said in a statement.

Cosmote’s Chief Technical Officer Lampros Iskos said the gradual development of the 4G network and the portfolio of products is continuous and in line with the company’s strategy aimed at extending the broadband network.
