ZenSim eSIM Data Plans for Portugal

ZenSim does not provide a truly unlimited data eSIM for Portugal. Its plans with the “Unlimited” label, such as Portugal Unlimited STANDARD, actually offer only 3GB of high‑speed data per day; once that amount is reached the speed is throttled (no specific reduced speed is listed). Travelers who need a larger amount of high‑speed data may choose one of ZenSim’s fixed‑data plans. For example, a 30‑day plan with 40GB of data is available for $45.00 USD, and a 30‑day plan with 20GB is available for $24.00 USD. These fixed‑data options can be more cost effective unless a user requires a high‑speed data allowance that exceeds 3GB per day on a daily‑reset basis.

ZenSim does not offer Portugal eSIM plans that include a phone number or SMS capability. The company only sells data‑only eSIMs for travel in Portugal. Travelers can still communicate using VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but there is no built‑in phone number or SMS service available with ZenSim’s Portugal eSIM.

ZenSim provides a total of 18 data plans for Portugal. There are nine single‑country plans dedicated to Portugal and an additional nine multi‑country plans that include Portugal among other destinations. The plans cover a price range of $11 to $57, with data caps spanning from 3 GB to 40 GB per validity period of 10 to 30 days. ZenSim offers both fixed data packages, which allow you to purchase a set amount of data that does not change day to day, and daily data cap plans, which limit the amount of data you can use each day within the validity period. Some plans also support tethering, enabling multiple devices to share the same connection.
