eSIM4Travel does not offer a truly unlimited data eSIM for Estonia. The plans that carry the name “Unlimited” provide 3GB of high‑speed data per day for a limited validity period and then throttle the speed to 1000 kbps; they are therefore fixed data plans, not unlimited.
Instead, eSIM4Travel offers a range of fixed data plans that may suit heavier data users. Examples include a 50GB/30‑day plan and a 20GB/30‑day plan both covering Estonia, which deliver unthrottled data throughout the validity period. These plans can be more cost‑effective for travelers who need more than a few gigabytes of data each day.
