Astaroam eSIM Data Plans for Portugal

Astaroam does not provide a true unlimited data eSIM for Portugal. The plans that carry the “Unlimited” name are fixed‑data plans that offer a set amount of high‑speed data per day—such as 1GB for 1 day or 3GB/day for up to 30 days. Once the daily allowance is reached, the speed is throttled to 1000kbps.

Travelers looking for a large allocation can choose from the fixed plans that list a high data cap, such as the 50GB plan for 30 days or the 20GB plan for 30 days, which provide full‑speed data for the entire validity period. These alternatives may offer a more cost‑effective solution unless a user requires truly unlimited high‑speed data.

Astaroam does not provide a Portugal eSIM that includes a local phone number or SMS capability. Travelers who need a phone number for calls or messages will find that only data‑only plans are offered by this provider. Instead, users can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to conduct voice and text communication, though it is advisable to confirm whether these services are fully accessible in Portugal before purchasing the plan.

Astaroam offers 14 single‑country plans and 26 multi‑country plans for Portugal. The plans range in price from $0.69 to $27.48 and provide data caps between 1 GB and 50 GB, with validity periods from 1 to 30 days. Among the offerings, 12 plans feature a daily data cap while 28 provide a fixed data amount, allowing travelers to choose between a set amount of data for the entire validity or a daily allowance that resets each day.
