TailSim does not provide a truly unlimited high‑speed data eSIM for Argentina. The plans marketed as “Unlimited” actually give a capped usage of 1 GB per day and reduce speed to 512 kbps once that daily limit is reached. Therefore, no plan offers unlimited data without restriction.
For travelers who need more data, TailSim offers fixed‑data plans such as 20 GB for 30 days or 10 GB for 30 days, which allow larger volumes of high‑speed data before any speed reduction. These fixed plans can be more cost‑effective for users with heavier data requirements.
