ZenSim eSIM Data Plans for Estonia

ZenSim does not provide a truly unlimited data eSIM for Estonia. The plans listed as “Unlimited” actually limit users to 3GB of high‑speed data per day; after that limit is reached the speed is throttled, and no further high‑speed data is available. If a traveler needs more data, ZenSim offers fixed‑data plans that may be more cost effective for heavy usage. For example, a 40GB plan for 30 days costs $45.00 USD, and a 20GB plan for 10 days costs $23.00 USD. These fixed plans can be chosen to secure the desired amount of data for the duration of the stay in Estonia.

ZenSim does not provide an Estonia eSIM plan that includes a phone number or SMS capability. The provider only offers data‑only eSIM plans for Estonia.

Travelers who need to make voice or text calls can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

ZenSim offers 9 single‑country plans and 9 multi‑country plans for Estonia, a total of 18 plans. The available plans range from $11.00 to $57.00 and provide between 3 GB and 40 GB of data. Users can choose between daily data cap plans, which limit data usage on a per‑day basis, and fixed data cap plans, which offer a set amount of data for the entire validity period; both types are available in the single‑ and multi‑country options. Tethering is allowed on some of the plans.
