ZenSim does not provide an unlimited‑data eSIM for Ukraine. The plans that carry the word “Unlimited” in their names actually offer a 3GB/day data cap; once that threshold is reached the speed would be throttled, though the exact reduced speed is not specified in the offers. Consequently travelers looking for truly unlimited high‑speed data will not find a suitable option with ZenSim in Ukraine.
Instead, ZenSim offers fixed‑data plans that can be useful if the user prefers a predictable data allowance. For example, the Ukraine 20GB plan is available for 10 or 30 days, and the Ukraine 10GB plan is sold for 10 days. These fixed‑data packages may prove more cost‑effective for most travelers, especially if they are not extremely heavy data consumers.
