Roambit does not offer any unlimited‑data eSIM plans for Portugal. All plans listed for Portugal are fixed data plans with a set data cap: for example, the Portugal 50GB 30d plan gives 50GB of data for 30 days at $24.99 USD, and the Portugal 20GB 30d plan offers 20GB for 30 days at $14.99 USD. Other high‑data options include the Europe 50GB 180d plan, which covers Portugal and 31 additional countries for 50GB over 180 days at $59.99 USD, and the Global 50GB 30d plan for 50GB in Portugal and 59 other countries at $99.99 USD.
Choosing a fixed data plan can be more cost effective for most travelers in Portugal, unless extremely heavy data usage is expected, in which case a pay‑as‑you‑go plan may be more appropriate.
