4S eSIM eSIM Data Plans for Estonia

4S eSIM does not provide a truly unlimited data eSIM for Estonia. All of its plans for Estonia have a fixed data allowance that must be used within a specified validity period. For example, the 50GB plan is available for 5 days, 7 days, or 15 days, and the 30GB plan is available for 15 days or 30 days. These fixed data plans offer large data allowances and can be more cost‑effective for travelers who need a substantial amount of high‑speed data without the need for an unlimited plan.

4S eSIM does not provide an Estonia eSIM that includes a phone number or SMS capability. The provider offers only data‑only eSIM plans for Estonia. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should check that these services are accessible in Estonia before purchasing.

4S eSIM provides 54 single‑country data plans that cover Estonia, and it also offers 108 multi‑country plans that include Estonia among their destinations. Across these options the price ranges from about $1.42 to $195.83, while the data caps vary from roughly 714 MB up to 50 GB over validity periods between one and 365 days. The company supplies both daily‑cap plans (39 plans) where the data is reset each day, and fixed‑cap plans (123 plans) that deliver a set amount of data for the entire validity period.
