gosimless does not provide any unlimited data eSIM plans for Estonia. Their offerings for Estonia are fixed‑data plans, the largest of which provide 50 GB of data for a set validity period. For example, the Estonia 50GB – 180 Days plan offers 50 GB for 180 days, and the Europe (31 areas) 50GB – 31 Days plan offers 50 GB for 31 days, both covering Estonia. Choosing a fixed plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer.
