JamboSim eSIM Data Plans for Portugal

JamboSim does not provide a truly unlimited high‑speed data eSIM for Portugal. Every plan that carries the “Unlimited” label gives a daily cap of 3 GB; once this amount is reached the speed is throttled to 1000 kbps.

Instead, JamboSim offers fixed‑data plans such as 100 GB for 180 days or 50 GB for 30 days, which can be more cost‑effective for heavy data users. These plans avoid the daily cap and speed throttling that applies to the “Unlimited” options.

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 provides 12 single‑country plans and 96 multi‑country options for travelers heading to Portugal. The plans are priced from $0.99 up to $195.99 and range in data from 200 MB to 100 GB. Some packages are fixed‑data, offering a set amount for the full validity period, while others impose a daily data cap to keep usage within a specified limit.
