JamboSim eSIM Data Plans for Portugal

JamboSim does not offer a truly unlimited high‑speed data eSIM plan for Portugal. The plans labeled “Unlimited” supply 3GB of high‑speed data per day, and once that daily limit is reached the speed is reduced to 1000kbps.

Travelers who need more data can choose from fixed‑data options that give full‑speed connectivity until the allowance is used. For example, a 20GB plan is valid for 30 days on a 5G network, and larger 50GB or 100GB plans are available with 30‑day or 180‑day validity. These fixed‑data plans can be more cost‑effective for heavy data users.

JamboSim provides several eSIM plans that include a phone number and the ability to send SMS while in Portugal. The plans range from 1 GB of data for 7 days at $11.99 USD to 20 GB of data for 365 days at $105.99 USD. Each plan grants a phone number with the dialing code +1, which is a North American number, not a local Portuguese number. Calls can be made from this number and SMS messages can be sent, but neither inbound calls nor inbound SMS are supported. Users wishing to confirm specific usage details or any changes to call and SMS capabilities should contact JamboSim directly.

JamboSim offers 12 single‑country data plans and 47 multi‑country data plans for Portugal. The available plans range in price from about $1.99 to $185.99, with data limits that span from 200 MB up to 100 GB. Some plans feature a fixed data amount that remains the same for the entire validity period, while others impose a daily data cap that resets each day. This variety lets travelers choose either a steady data allotment for longer trips or a flexible daily cap for shorter stays.
