airdatalink eSIM Data Plans for Portugal

AirDataLink does not currently provide any truly unlimited data eSIM plans for Portugal. The available options are fixed‑capacity plans, primarily offering 50 GB or 30 GB of high‑speed data for a 30‑day period. For example, the Essential Europe eSIM includes 50 GB for $23.65 USD, while a 30 GB variant is available for $16.08 USD. These plans also support tethering and cover Portugal as well as a range of neighboring European countries.

Choosing a fixed data plan can be a more cost‑effective solution for most travelers, unless a user anticipates extremely heavy data usage that would exceed the caps of the available packages.

airdatalink does not provide a Portugal eSIM that includes a local phone number or SMS capability. All eSIM plans from this provider for Portugal are data‑only, so travelers cannot make or receive traditional phone calls or texts. However, voice and messaging still be accomplished over the data connection using VoIP applications such as WhatsApp, Telegram, and iMessage.

Airdatalink provides a range of data plans for Portugal that include 5 single‑country options and 46 multi‑country options, giving users the flexibility to choose a plan that is either limited to Portugal or covers multiple destinations in the region. Prices for these plans start at about US $2.60 and go up to roughly US $47.10, while data caps vary from 500 MB up to 50 GB. In addition to fixed‑data plans, there are daily‑cap plans available, and validity periods range from 5 to 90 days.
