AlpineSIM eSIM Data Plans for Portugal

AlpineSIM does not provide an unlimited‑data eSIM plan for Portugal. All of its “Unlimited” named plans have a capped high‑speed data allowance, such as 300 MB/day, 1 GB/day, or 5 GB/day, after which the speed may be reduced to a lower tier.

Instead, AlpineSIM offers fixed‑data eSIMs that can be suitable for longer stays or heavier usage. A 20 GB plan is available for 30 days at $15.82 USD, and a 50 GB plan is offered for 30 days at $39.52 USD. These options give a clear amount of high‑speed data for the flight period and are often more cost‑effective for travelers who need substantial data.

AlpineSIM does not offer a Portugal eSIM with a phone number or SMS. Only data‑only plans are available for that destination.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage to make calls and send messages over the data connection.

AlpineSIM provides 7 single‑country plans that include Portugal, and 140 multi‑country bundles that also cover Portugal. The single‑country options deliver a fixed data amount for a set validity period, while the multi‑country packages may offer a daily data cap that replaces a single large data pool. Prices range from $0.65 to $229.95 and data caps vary between 300 MB and 50 GB.
