AirPlans eSIM Data Plans for Portugal

AirPlans does not provide a truly unlimited data eSIM for Portugal. All of its plans that carry the word “Unlimited” in the name actually have a fixed data allowance, such as 1 GB for a 1‑day plan or 3 GB per day for multi‑day plans. After the allotted data is used, the speed is reduced to a lower rate, for example 512 kbps or 1000 kbps.

Travelers who need more data can choose from AirPlans’ fixed data plans, such as the Portugal Unlimited 3 Days plan that offers 3 GB per day for 3 days or the Portugal Unlimited 10 Days plan that provides 3 GB per day for 10 days. These plans give a larger data allowance than the 1‑day “Unlimited” options, but they still have a hard cap and a reduced speed once the limit is reached.

AirPlans does not provide a Portugal eSIM plan that includes a phone number or SMS capability. The provider offers only data‑only eSIMs for this destination. Travelers can still use voice and messaging through VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but some destinations may block or restrict access to these services, so visitors should confirm that the apps they need work in Portugal before purchasing.

AirPlans offers 35 single‑country plans that include Portugal and 100 multi‑country plans that cover Portugal as part of a broader regional bundle. The plans range in price from about $1.30 to $284.25 and provide data caps between 500 MB and 100 GB. Among the available options, 80 plans feature a daily data cap—where the data allowance is reset each day—while 55 plans offer a fixed data cap that applies for the entire validity period.
