Slovakia’s newest cellco, Telefonica O2 Slovensko, has announced that it is ready to launch its own GSM network, with an initial 400 base stations to be in operation by the end of this month. It plans to double the number of base stations within a year, and roll out services to each of the country’s regions, including mountainous areas, in phases. Telefonica O2 won a combined GSM/UMTS licence in August 2006 and launched commercial services in February 2007 with an offer of unlimited on-network calls for SKK2 (USD0.08) a minute. The GSM service is initially relying on a national roaming deal with rival T-Mobile Slovensko, which will be maintained whilst the young operator builds out its own network. Telefonica O2 reported that it had over 400,000 active customers as of 19 April, out of a total of over 600,000 that registered for its pre-paid packages.
