4S eSIM eSIM Data Plans for Estonia

4S eSIM does not provide a truly unlimited data eSIM for Estonia. Plans that contain “Unlimited” in the name, such as Estonia 50GB Unlimited – 5 Days, still have a fixed high‑speed data allowance (10GB/day in that case) and, once the limit is reached, the data speed is throttled to 1000kbps.

Travelers who need large data volumes for Estonia can choose fixed‑data plans. For example, the Estonia 50GB for 5 days plan offers a full 50GB of high‑speed data for that duration, and the Estonia 30GB for 15 days plan provides 30GB over two weeks. These fixed‑data options are generally more cost‑effective for heavy data users than the capped “Unlimited” plans.

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.
