TailSim does not provide an unlimited data eSIM for Estonia. All of its plans for the country have a fixed data allowance.
Travelers can choose from fixed data plans such as the 50 GB plan for 30 days priced at $72.99 USD, the 20 GB plan for 30 days priced at $21.99 USD, or the 10 GB plan for 30 days priced at $13.99 USD. These options offer a set amount of high‑speed data that must be used within the 30‑day validity period, and they can be more cost‑effective for most users unless very heavy data consumption is expected.
