RoameSIM eSIM Data Plans for Portugal

RoameSIM does not provide a true unlimited data eSIM for Portugal. All plans labeled “Unlimited” are fixed data bundles that supply 3GB of high‑speed data each day; after 3GB of usage per day the speed drops to 1000kbps.

These fixed plans can be chosen for different validity periods, for example the Portugal‑Only “Unlimited – 30 days” plan gives 3GB/day for 30 days, or a broader “Europe – Unlimited – 30 days” plan gives the same daily allowance for 30 days across Portugal and other European countries. While the daily cap may suit many travelers, the plans are not truly unlimited and are more cost‑effective for moderate data usage.

RoameSIM does not provide prepaid eSIM plans for Portugal that include a local phone number or SMS service. Only data‑only eSIMs are available for that country.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may restrict access to these services. It is advisable to verify that the apps you rely on remain accessible in Portugal before purchasing a plan.

RoameSIM provides 28 single‑country data plans and 37 multi‑country data plans for Portugal. The single‑country plans give customers a dedicated data allocation for use only in Portugal, while the multi‑country plans bundle Portugal with additional European destinations. Plans are offered in two main styles: fixed data amounts—where you purchase a specific amount (e.g., 1 GB, 10 GB, up to 100 GB) that can be used over the validity period—and daily data caps—where you pay for a data allowance that refreshes each day (typically tuned to 500 MB up to 10 GB per day). Pricing for these plans spans roughly $3.44 to $437.50 USD, and data cap options range from 500 MB up to 100 GB, giving travelers a broad selection to fit short stays or extended trips.
