No, WonderConnect does not provide an unlimited data eSIM for Estonia.
The provider’s plans for Estonia are fixed data bundles, all offering 50 GB of data valid for 30 days. For example, the “Estonia” plan supplies 50 GB at a price of $28.49 USD and the “Ukraine, ” “Serbia, ” “Moldova, ” and “North Macedonia” plans also give 50 GB for 30 days with the same price or a slightly higher one. These fixed data plans may be more cost‑effective than Pay‑as‑you‑go alternatives for most travelers, unless a user expects to consume far more data than the 50 GB allowance.
