Roamingo does not provide a truly unlimited high‑speed data plan for the Netherlands. The only plan with “Unlimited” in its name, Europe Unlimited for 1 day, actually allocates 2GB of high‑speed data; once that allotment is reached the connection speed is throttled.
Instead, Roamingo offers fixed‑data plans that cover the country, such as Netherlands 20GB for 30 days at $25.50 USD or Netherlands 10GB for 30 days at $14.50 USD. If a user needs a larger data allowance, these fixed‑data options tend to be more cost‑effective unless they will consume data at a very high volume.
