Astaroam eSIM Data Plans for Croatia

Astaroam does not provide a truly unlimited data eSIM for Croatia.
The plans labeled “Unlimited” give 3 GB of high‑speed data per day; once that limit is reached the speed is throttled to 1000 kbps.

If you need a larger amount of data without a daily cap, Astaroam offers fixed‑data packages such as 20 GB for 30 days, which may be more cost‑effective for heavy users.

Astaroam does not provide a Croatia eSIM that includes a phone number or SMS capability. The only plans available for Croatia from this provider are data‑only eSIMs, so travelers will not receive an existing mobile number or the ability to send or receive text messages directly with the eSIM. However, users can still make and receive voice calls and send messages through popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. Keep in mind that some destinations may block or restrict certain VoIP services, so it is advisable to confirm that the apps you use are accessible in Croatia before purchasing a plan.

Astaroam offers six single‑country plans covering Croatia, and a broader selection of 41 multi‑country plans that include Croatia. The available plans span a price range of roughly $1.98 to $48.54, with data caps varying from 500 MB up to 20 GB. Among the catalog, some plans provide a fixed data amount while others impose a daily data cap, giving travelers flexibility depending on whether they prefer a set total for the validity period or a daily allowance that limits usage throughout the plan’s lifespan.
