ByteSIM does not provide a truly unlimited data eSIM plan for Estonia. All packages that carry "Unlimited" in the name actually supply a maximum of 1GB of high‑speed data per day, and after that threshold the speed is reduced to 10240kbps. Travelers who need more data can choose fixed‑data plans instead. For instance, ByteSIM offers a 50GB plan that lasts 3 days for $40.90 USD, a 50GB plan for 10 days for $48.90 USD, and other similar options. These larger‑capability plans may be more cost‑effective for heavy data users who do not require an unlimited daily quota.
