Astaroam eSIM Data Plans for Serbia

Astaroam does not provide a truly unlimited high‑speed eSIM for Serbia. Every plan labelled “Unlimited” is capped at 3 GB of data per day; after the daily quota is reached the speed drops to 1000 kbps.

Instead, Astaroam offers fixed‑data options that give travelers a larger amount of high‑speed data upfront. For example, a 20 GB plan valid for 30 days costs $15.32 USD, and a 10 GB plan for the same period is $10.02 USD. Both plans include tethering and may be more cost‑effective for most users than the capped daily “Unlimited” options.

Astaroam does not offer a Serbian eSIM with a local phone number or SMS capability; their Serbian plans are purely data‑only. Travelers who need voice or text can use internet‑based services such as WhatsApp, Telegram or iMessage over the data connection, but they should verify that these VoIP apps are accessible in Serbia before purchasing, as some destinations may block or restrict certain applications.

Astaroam offers 11 single‑country data plans and 11 multi‑country plans for travelers in Serbia. Among these plans, data caps range from 1 GB to 20 GB and prices fall between approximately $2 and $49. The catalogue includes 18 fixed‑data plans that provide a total data allotment for the entire validity period, as well as 4 daily‑cap plans that reset each day during the validity window. All plans stay active for 3 to 30 days and may permit tethering or reduced speed usage.
