Slovakia: Mobile Coverage & Carriers
ESIMBYCOUNTRY at checkout · See all codes →Slovakia has four mobile network operators: Orange, Telekom, O2, and 4ka. The country supports 3G, 4G/LTE, and 5G services. Roaming travelers using an eSIM should expect coverage on LTE bands B20 (800 MHz), B3 (1800 MHz), and B7 (2600 MHz), with 5G available on band n78 (3.5 GHz) in areas where deployed.
Some of Slovakia's local carriers offer eSIM services, though availability and support may vary by operator. A roaming eSIM user will likely connect to one of the four national operators depending on location and roaming agreements.
