Best eSIM for Split in 2026
— Ranked by Real Performance

Split sits on the Dalmatian Coast with surprisingly strong LTE and growing 5G coverage, anchored primarily by Hrvatski Telekom (HT) — the Deutsche Telekom subsidiary that dominates with roughly 97% population coverage across Croatia. It's a solid destination for remote workers and island-hopping travellers alike, though the ferry routes to Hvar and Brač expose the one real weakness: maritime coverage drops sharply beyond 2km offshore, something no eSIM provider can fix regardless of their marketing claims. Most consumer eSIMs route through HT or Tele2 Croatia at the wholesale level, making carrier selection more important than brand here.

• →Hrvatski Telekom holds approximately 97% population coverage in Croatia and is the dominant wholesale partner for most eSIM MVNOs operating in Split — meaning your actual signal depends heavily on whether your eSIM provider has a direct HT agreement or is rerouting via a regional hub.
• →Split's city centre and Diocletian's Palace area consistently achieves LTE Category 6 speeds (theoretical 300Mbps downlink), with real-world measured averages typically in the 40–80Mbps range — fast enough for 4K streaming and video calls without interruption.
• →5G in Split is available but limited to select urban corridors along Domovinskog rata street and the waterfront Riva promenade as of 2024; HT and A1 Croatia are the two operators with active 5G NR deployments, but most eSIMs will fall back to LTE unless specifically provisioned on an A1 or HT 5G-capable profile.
• →Croatia has been in the EU roaming zone since 2023 full integration, but eSIM MVNOs operating under non-EU wholesale licences (some Middle East or Asia-headquartered providers) may still apply fair-use data caps that differ from EU roaming regulation guarantees — check the provider's registered jurisdiction, not just their marketing.
