You do not get a new phone number with this eSIM.
Setting up your eSIM? The installation and activation guide walks through it step by step, and the full FAQ covers device compatibility, hotspot, dual SIM and topping up.
One plan covers Croatia end to end - Dubrovnik, Split, Zagreb and the islands - so the same eSIM works across the whole Adriatic trip. Install it before you travel, switch off airplane mode on arrival, and you are online straight away.
The eSIM connects when you turn off airplane mode at Dubrovnik (DBV), Split (SPU) or Zagreb (ZAG). Your transfer, ferry booking and maps are ready before you reach the bus or the old-town walls.
Croatia's networks (Hrvatski Telekom, A1 and Telemach) cover the Dalmatian coast, the cities and the popular islands - Hvar, Brac, Korcula - with strong 4G and 5G in the main towns. Coverage holds near the coast on most ferry routes, with occasional dips on longer crossings.
Yes - the Croatia plan covers the mainland coast plus the popular Dalmatian islands, so the same eSIM works on the islands and in Dubrovnik or Split.
Generally yes near the coast and on shorter routes; longer open-water crossings can briefly drop signal.
