TailSim eSIM Data Plans for Portugal

TailSim does not provide a true unlimited data eSIM for Portugal. All of its “Unlimited” plans listed in the dataset are fixed‑data plans that allow 3GB of high‑speed data each day; after the daily allowance is used, the speed is throttled to 1000 kbps.

For travelers who need more data without speed reduction, TailSim offers fixed plans such as the 10 GB – 30 days, 20 GB – 30 days, and 50 GB – 30 days options, all of which give the full data amount at 5G speeds until the 30‑day period expires.

TailSim does not offer eSIM plans for Portugal that include a phone number or SMS capability. The provider only offers data‑only eSIMs for this destination; over the data connection travelers can use popular VoIP applications such as WhatsApp, Telegram, or iMessage for voice and messaging. However, some destinations may block or restrict certain apps or VoIP services, so users should verify that the apps they need are accessible in Portugal before purchasing a TailSim eSIM.

TailSim offers 14 single‑country plans and 14 multi‑country plans that cover Portugal. Among its plans, 16 are daily‑data‑cap tariffs that provide a set amount of data each day during the validity period, whereas 12 are fixed‑data‑cap plans that give a fixed quantity of data for the entire duration. Overall, TailSim’s plans range in price from about $3.99 to $85.50 and in data limits from 1 GB up to 50 GB.
