ByteSIM does not provide a true unlimited high‑speed data eSIM for Ukraine; all of its plans have a fixed data allowance. The plans labeled “Unlimited,” such as Ukraine Unlimited Data for 1 day and the 7‑day version, actually include 1GB per day of high‑speed data and then reduce speed to 10240kbps after the limit is reached.
For travelers who need more data, ByteSIM offers fixed‑amount plans that can be more cost effective. For example, the Ukraine 50GB plans are available for 3, 5, 7, 10, or 15 days, allowing a larger volume of data without speed throttling after the allowance is used. These fixed plans are a practical alternative to the capped “Unlimited” options.
