ZenSim eSIM Data Plans for Estonia

ZenSim does not provide a truly unlimited high‑speed data eSIM for Estonia. The plans labelled “Unlimited” only give 3GB of high‑speed data per day; once that daily allowance is reached the speed will be throttled. Travelers looking for larger data allowances can choose from ZenSim’s fixed plans such as the Estonia 20GB‑10 Days for 10 days or the Estonia 10GB‑10 Days. These options give a set amount of highspeed data before any throttling occurs, which may be more cost‑effective for most users.

ZenSim does not provide an Estonia eSIM plan that includes a local phone number or SMS capability. The only plans available from ZenSim for Estonia are data‑only eSIMs, meaning they can be used for Internet access but do not support inbound or outbound calls or text messages through the device. Travelers who need messaging or calling can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which do not require a phone number or SMS support.

ZenSim offers 8 single‑country data plans for Estonia and another 8 multi‑country plans that include Estonia. The packages are priced between $11 and $57 and provide data capacities ranging from 3 GB to 20 GB with validity periods of 10 to 30 days. Some options grant a daily data cap, while others deliver a fixed data allotment, giving travelers flexibility to match their usage pattern; tethering is allowed on many of the plans.
