shibaSIM does not provide a truly unlimited data eSIM for Paraguay. All of its plans list a specific data cap, such as 1GB/day or 2GB/day, and after that daily high‑speed allowance is reached the speed is reduced to 128kbps.
The plans are fixed data plans. For example, the Multi‑region (incl. China) Unlimited (1GB/day high speed) for 1 day plan gives 1GB of high‑speed data for 1 day, and the South America (8 countries) Unlimited (2GB/day high speed) for 5 days plan gives 2GB of high‑speed data each day for 5 days. These options can be more cost‑effective for most travelers, but they are not unlimited.
