Rufly does not provide a genuinely unlimited data eSIM for Estonia. All of their available plans for Estonia have a hard limit of 500MB per day. Instead, they offer fixed data plans—such as the “Europe Unlimited 7 days, ” “Europe Unlimited 15 days, ” and “Europe Unlimited 30 days” options—which give 500MB each day at full speed and then reduce speed after the day's allowance is used. According to the provider’s notes, after 30 GB, 45 GB, and 70 GB of total data used on the respective plans the speed drops to 512 Kbps. These fixed plans can be a cost‑effective choice for most travelers, but they are not the same as true unlimited data plans.
