iRoamly does not provide an unlimited data eSIM plan for Croatia. The provider offers fixed data plans that include caps such as 90 GB for 365 days and 50 GB for 3 or 5 days, all of which are available on 5 G networks. Travelers needing a large amount of data may find the 90 GB/365‑day plan suitable, while those staying only a few days might opt for the 50 GB/3‑day or 50 GB/5‑day plans. Depending on usage, fixed data plans can be more cost‑effective unless the user is a very heavy data consumer.
