3G Network

Slovak Telekom launched its 3G network in Slovakia on August 22, 2006. The network initially provided 21 Mbps HSPA+ services, which were later upgraded to 42 Mbps DC-HSPA+ on October 19, 2011. The company planned trials for 84 Mbps but focused on enhancing its existing services. The 3G network played a crucial role in expanding mobile internet access across Slovakia. However, in line with global trends towards newer technologies, Slovak Telekom began the phased shutdown of its 3G network in October 2023. The shutdown was planned to conclude before Christmas 2023, with the spectrum being repurposed for 4G and 5G services. This transition aimed to improve network capacity and performance, focusing on modern technologies.
