MobileSIM eSIM Data Plans for Portugal

MobileSIM does not provide a truly unlimited data eSIM for Portugal. All plans that carry the word “Unlimited” in their name actually allot a fixed amount of high‑speed data—3 GB per day for the duration of the validity period—and once that limit is reached the speed is reduced to 1000 kbps.

Travelers looking for a high‑capacity option can choose from MobileSIM’s fixed‑data plans. For example, the “Portugal Unlimited data for 30 days” plan offers 3 GB of high‑speed data each day for 30 days, costing $69.00 USD. A larger flat‑data bundle is also available: “Portugal 20 GB for 30 days” provides 20 GB of data for 30 days at $19.00 USD. These fixed‑data plans can be more cost‑effective than a true unlimited plan for most users.

MobileSIM does not offer a Portugal eSIM plan that includes a local phone number or SMS capability. Travelers can purchase a data‑only eSIM and use VoIP services such as WhatsApp, Telegram or iMessage to make calls and send messages, but they should confirm that these apps are accessible in Portugal before buying.

MobileSIM offers 12 single‑country plans and 10 multi‑country plans for Portugal. The plans range in price from $2.30 to $165.00 and offer between 200 MB and 60 GB of data, with validity periods from 3 to 125 days. Some plans use a daily data cap, limiting usage each day, while others provide a fixed data amount that can be used anytime within the validity period; MobileSIM lists 6 daily‑cap plans and 16 fixed‑cap plans across its offerings.
