shibaSIM does not provide a truly unlimited data eSIM for Ukraine. Every plan that lists “Unlimited” in its name contains a fixed high‑speed data allowance per day, after which the speed is reduced to 128kbps. Travelers can choose from fixed data plans such as the Europe (44 countries) Unlimited (3GB/day high speed) for 10 days, which offers 3GB of high‑speed data each day for a 10‑day validity, or the Europe (44 countries) 30GB for 30 days plan, which provides a one‑time 30GB allowance usable over 30 days. These fixed plans can be more cost‑effective unless a user requires continuous high‑speed data beyond the daily caps.
