4S eSIM does not provide a truly unlimited data eSIM for Ukraine. All plans listed in the provider’s catalogue have a fixed data allowance, such as 40GB for 365 days or 20GB for 10 days, and even the plans that carry the word “Unlimited” in their name give a capped amount of high‑speed data per day (3GB or 5GB per day) with speed throttled to 1000kbps once the limit is reached.
When travelers need more data, the fixed‑data options can be more cost‑effective. For example, the Ukraine 40GB plan valid for 365 days delivers a large, predictable amount of high‑speed data, while lighter users may choose a smaller plan like the Ukraine 20GB plan for 10 days. These alternatives avoid the post‑limit slowdown that occurs with the “Unlimited”‑named plans.
4S eSIM does not provide eSIMs for Ukraine that include a phone number or the ability to send or receive SMS. All Ukraine plans from this provider are data‑only, so you will not receive a local number to make conventional calls or receive texts.
You can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make voice or video calls and send messages, which is the common solution for travelers who need communication services while traveling.
4S eSIM provides 35 single‑country plans that include Ukraine and 144 multi‑country plans that cover Ukraine. The offerings include both daily‑data‑cap and fixed‑data‑cap options; daily caps limit the amount of data available each day, while fixed caps give the user a total data allocation for the entire validity period. Across all plans the price ranges from about $1.40 to $329.64, and the data caps span from 300 MB up to 50 GB.
