merdata does not provide an unlimited data eSIM for the Nordic region. The available options in this area are fixed data plans, each supplying 50GB of high‑speed data and a specified validity period. For example, a 50GB plan for 30 days costs $32.24 USD, a 50GB plan for 90 days costs $64.59 USD, and a 50GB plan for 180 days costs $75.38 USD. These plans cover Denmark, Finland, Iceland, Norway, Sweden, and neighboring countries.
Because the data allowance is limited to 50GB, a fixed plan may be more economical for most travellers, especially those who are heavy data users, as they can choose a longer validity to spread usage and are able to purchase additional credit if needed.
