nextSIM eSIM Data Plans for Portugal

nextSIM does not provide a truly unlimited high‑speed data plan for Portugal. All plans listed under the “Unli­mited” name have a data cap of either 1GB or 2GB; once that limit is reached the speed is throttled to 512kbps or 2000kbps. Because the data allowance is capped, these plans are not considered unlimited for high‑speed usage.

Instead nextSIM offers fixed‑data plans that give larger, unthrottled data allowances for a set period. For example, a 100GB plan for 30 days costs $70.69 USD, and a 50GB plan for 30 days costs $197.65 USD. These fixed‑data options can be more cost‑effective for travelers who need substantial data without the speed restrictions that apply after the “unlimited” caps are reached.

nextSIM does not offer a Portugal eSIM that includes a phone number or SMS capability. The provider provides only data‑only plans for Portugal. Travelers who need voice or text can use internet‑based applications such as WhatsApp, Telegram, or iMessage, which work over the data connection and allow calls and messaging without a local phone number.

NextSIM offers 21 single‑country plans and 45 multi‑country plans for Portugal. Prices range from about $2.03 to $1,278.92, while data caps vary from 1 GB to 100 GB and validity periods run from 1 to 365 days. For customers who prefer a set data amount for the entire validity, 36 plans provide fixed data caps, whereas 30 plans offer a daily data cap that resets each day.
