Astaroam eSIM Data Plans for Portugal

Astaroam does not provide a truly unlimited data eSIM for Portugal. Every plan that carries the “Unlimited” label actually limits high‑speed data to 3GB per day and reduces the speed to 1000kbps once that daily quota is reached.

Travelers who need more data can choose from Astaroam’s fixed‑data plans. For instance, the Portugal 50GB 30Days plan offers 50GB of high‑speed data for 30 days at $27.50 USD, and the Portugal 20GB 30Days plan provides 20GB for $7.32 USD. These options give larger data allowances without the speed throttling that applies to the “Unlimited” plans.

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 supplies 14 single‑country data plans that cover Portugal and 28 multi‑country plans that include the country. The plans run from a single day to a month and cost between $0.69 and $27.50. The data limits spread from 1 GB to 50 GB. Some of these plans use a fixed data amount while others apply a daily data cap; the daily‑cap options allow different usage limits each day whereas fixed‑cap plans provide the same total amount for the entire validity period. Tethering is permitted and speed is reduced to 1000 kbps after the cap is reached.
