AlpineSIM eSIM Data Plans for Portugal

AlpineSIM does not provide a true unlimited‑data eSIM for Portugal. Every plan listed with an “Unlimited” title is actually capped, offering between 300 MB/day and 5 GB/day of high‑speed data; once the daily limit is reached, speed is throttled according to the plan’s reduced‑speed setting.

For travelers who need more data, AlpineSIM sells fixed‑data eSIMs that ship larger allowances. For example, a 50 GB plan valid for 30 days costs $36.96 USD, and a 100 GB plan that is valid for 180 days costs $80.86 USD. These larger plans may be a more cost‑effective option for heavy data users.

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 offers 7 single‑country data plans that keep you in Portugal only, and 148 multi‑country data plans that include Portugal among many other destinations. The single‑country packages range from a small 300 MB plan to 100 GB, with prices from $0.61 to $223.45. The multi‑country options cover the same data and price spectrum, giving travelers continuous service for longer stays. Some plans give a fixed data amount for the full validity period, while others apply a daily data cap; a handful of packages also allow tethering.
