The product spec on this page lists the Slovenia eSIM as 4G/LTE. The A1 Slovenia network supports nationwide 5G with the country's fastest measured 5G speeds, but this eSIM may connect at 4G/LTE only depending on the partner roaming arrangement. 4G/LTE in Ljubljana typically delivers 30 to 100 Mbps — fast enough for streaming, video calls, navigation, and remote work without issue. If 5G is essential for your use case, confirm with ETravelSim support before purchase.
