Slovenia: Mobile Coverage & Carriers
ESIMBYCOUNTRY at checkout · See all codes →Slovenia has three major mobile network operators: Telekom Slovenije, A1, and Telemach. All three networks support 4G/LTE and 5G services. The country has 3G infrastructure in place as well, though 5G deployment continues to expand. Roaming users and local subscribers typically connect via LTE bands B20 (800 MHz), B3 (1800 MHz), and B7 (2600 MHz), with 5G services primarily using the n78 band at 3.5 GHz.
Some local carriers in Slovenia offer eSIM services, though availability may vary by provider. For travelers or those seeking mobile connectivity, both traditional SIM cards and eSIMs represent potential options depending on the carrier selected. Network coverage and technology support are generally well-established across the country's three major operators.
