4ka

What 4ka does

4ka is the consumer telecommunications brand of SWAN, a.s. (a private Slovak joint-stock company within the DanubiaTel holding group), operating as the fourth mobile network operator in Slovakia since its October 2015 launch. It provides mobile voice, SMS, and data services under both prepaid (credit-based) and postpaid (SLOBODA) tariff structures, alongside fixed home internet (optical fiber and fixed wireless), digital television (4KA TV), and add-on services including eSIM, VoLTE/ViLTE, VoWiFi, HBO/Max content bundles, and the Whalebone-powered 4KA OCHRANA cybersecurity product. Underlying technology comprises its own nationwide 4G/LTE network with 97% population coverage (via both owned infrastructure and an Orange Slovakia network-sharing agreement), a 5G network exceeding 53.5% population coverage as of mid-2026, and owned optical/fiber infrastructure reaching over 2 million Slovak households.

The business model combines recurring subscription revenue (postpaid mobile, fixed internet/TV bundles, family tariffs priced at €15.75/person/30 days for 4 sharers), usage-based prepaid revenue (€0.051/min/SMS, €0.0144/MB), hardware sales (smartphones, watches, consoles), and emerging subscription revenue from cybersecurity (4KA OCHRANA). It serves primarily individual Slovak consumers (with sub-segments for youth/students under "SLOBODA pre mladých" and families under the family tariff) and residential households, plus a smaller SMB/enterprise tier. Go-to-market is hybrid: direct-to-consumer via its own e-shop and Moja 4ka self-serve app, complemented by a 1,700+ point-of-sale physical network that includes every Slovak Post office and a 50+ store Smartshop franchise operation.

The company scales distribution heavily through the Slovak Post partnership and a growing Smartshop franchise program (partners earning approximately €50K annually on average), while running its own nationwide radio and fiber infrastructure. As of 2025 the customer base exceeds 700,000 (some sources citing 760,000-800,000 paid services, up from 603,000 in 2022), and 4ka has been named the most popular Slovak operator in KPMG's customer experience survey for three consecutive years. It is notable as the only major Slovak telecom with majority Slovak capital.
