4S eSIM does not provide a truly unlimited data eSIM for Ukraine. Plans that carry “Unlimited” in the name actually include a fixed data cap – for example, the Ukraine 3GB Unlimited – 1 Days plan delivers 3GB of high‑speed data and after the cap is reached the speed is reduced to 1000kbps.
If a user needs a large amount of high‑speed data without a hard cap, 4S eSIM offers fixed‑data alternatives. For instance, the Ukraine 50GB – 5 Days plan gives 50GB of high‑speed data for five days, and the Ukraine 30GB – 30 Days plan provides 30GB over thirty days. These fixed‑data plans can be a more cost‑effective choice for travelers who consume a lot of data.
4S eSIM does not provide eSIM plans for Ukraine that include a phone number or SMS capability. Only data‑only eSIM options are available for this destination. Travelers can use data‑based VoIP applications—such as WhatsApp, Telegram, or iMessage—to make voice calls and send messages, but some destinations may block or restrict certain apps or VoIP services, so it is advisable to verify that the applications you rely on are accessible in Ukraine before purchasing a plan.
4S eSIM offers a total of 162 data plans that include coverage of Ukraine, consisting of 54 single‑country plans that focus exclusively on Ukraine and 108 multi‑country plans that bundle Ukraine with other destinations. The plans cover a wide spectrum of data amounts, from 714 MB up to 50 GB, and validity periods ranging from one day to one year. Pricing varies between approximately $1.38 and $195.83, depending on the data volume and duration. Among the available options, 39 plans have a daily data cap while 123 plans provide a fixed data cap for the entire validity period. This mix allows travelers to choose a plan that best fits their use‑case, whether they need a compact daily allotment or a larger, sustained data allowance for longer stays.
