Coverage in Slovenia

Mountainous terrain and forested areas cause significant coverage gaps in rural Alpine regions; some remote valleys have no service on any network.

Common Questions

The details worth knowing about your Slovenia eSIM

The eSIM connects to Telekom Slovenije, A1 Slovenija and Telemach Slovenija. All three cover major cities and highways with 4G and 5G. In rural Alpine areas and remote valleys, coverage gaps are common regardless of operator, so expect no service in some mountain locations.

All three Slovenian operators use 5G bands n28 and n78. If your phone lacks these bands, you will fall back to 4G. Most US phones sold after 2020 include n78, but older models and some Chinese phones may miss one or both bands, reducing high-speed coverage.

No. The eSIM only connects to Slovenian networks. Once you cross the border into Italy, Austria, Hungary or Croatia, the service stops. Roaming into neighbouring countries is not included. Plan a separate eSIM or local SIM before leaving Slovenia.

Data is not filtered or throttled by the eSIM or the local operators. You get full speed up to the plan limit. Median download speed across Slovenia is 55.82 Mbps. No content blocks or VPN restrictions apply on any of the three networks.

Coverage is unreliable in mountainous terrain and forested Alpine areas. Telekom, A1 and Telemach all have significant gaps in rural valleys and high elevations. Some remote valleys have no service on any network. Expect no signal for extended stretches while hiking or driving off main roads.
