nextSIM does not provide a genuinely unlimited data eSIM for Ukraine. Plans that contain “Unlimited” in the name actually supply a fixed amount of high‑speed data and then throttle the connection—either to 512 kbps after 1 GB or to 2000 kbps after 2 GB. For example, eSIM Unlimited Standard 1 Day Ukraine gives 1 GB with a reduced speed of 512 kbps once the limit is reached.
Instead, nextSIM offers fixed data plans that enable users to access larger pools of high‑speed data without throttling until the cap is hit. Examples include the eSIM EUROPE 50GB 30Days Premium plan, which offers 50 GB for 30 days at $198.94 USD, and the eSIM EUROPE 30GB 30Days Premium plan, which provides 30 GB for 30 days at $119.37 USD. For travelers who anticipate heavy data use, a fixed‑data plan can often be more economical than the reduced‑speed “unlimited” options.
