Astaroam eSIM Data Plans for Croatia

Astaroam does not provide a truly unlimited data eSIM for Croatia. The plans that carry the word “Unlimited” in their name actually offer a fixed amount of high‑speed data—3 GB per day for the duration of the plan—after which the speed is throttled to 1000 kbps. For travelers who need more data without a hard cap, Astaroam offers fixed data plans such as the 20 GB 30‑day option, which delivers 20 GB of high‑speed data for a month. These fixed plans can be more cost‑effective for most users, while the “Unlimited” plans provide a larger daily allowance at a higher price.

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 lists 6 single‑country plans and 37 multi‑country plans that cover Croatia. The single‑country options range from about $0.93 to $48.21, with data caps between 1 GB and 20 GB and validity periods from 1 to 30 days. The multi‑country bundle offers a similar price and data range, but users can travel to other countries included in the bundle while retaining the same data allocation. Both sets of plans include a mix of fixed‑data packages—where a set amount of data is available for the plan’s entire validity—and daily‑cap packages, which refresh the data allowance each day. Overall, users can choose from a broad range of price points and data limits to suit short trips or longer stays.
