ZenSim does not provide a truly unlimited eSIM plan for Ukraine. The plans that carry “Unlimited” in the name—such as Ukraine Unlimited STANDARD for 10 or 30 days—actually offer a fixed allowance of 3 GB per day. Once that daily quota is exceeded, the high‑speed data rate is reduced, so the service is not unlimited in the sense of continuous, unrestricted high‑speed data.
Travelers who need a large amount of data can instead choose from ZenSim’s fixed‑data options. For example, a 20 GB plan for 10 or 30 days is available in Ukraine at $23.00 and $24.00 respectively, while a 10 GB 10‑day plan costs $15.00. These fixed plans may be more cost‑effective for users who require substantial data usage but do not need an unlimited allowance.
