ZenSim does not provide a truly unlimited data eSIM for the Balkans. The only plan that carries “Unlimited” in its name is the Balkans+ Unlimited STANDARD – 5 Days plan, which offers 3GB of high‑speed data per day for 5 days; after the daily limit is reached the speed is throttled to 1000kbps.
Travelers who need more data can choose from ZenSim’s fixed data plans. For example, the Balkans+ 40GB plan is valid for 30 days and the Balkans+ 20GB plan is available for either 15 or 30 days. These plans provide a set amount of high‑speed data that must be used within the specified validity period.
