eSIMCard does not provide a truly unlimited high‑speed data eSIM for Sri Lanka. Every plan labeled “Unlimited” in its name actually contains a fixed data cap of 1 GB per day; once the cap is reached the connection speed is reduced to 500 kbps (or 2000 kbps for some “Unlimited Plus” variants). Consequently these packages are not unlimited in the sense of providing endless high‑speed data without limits.
Instead, eSIMCard offers fixed‑data plans for travelers in Sri Lanka. For example, a 100 GB data package valid for 180 days costs $185.68 USD, and a 50 GB plan for 30 days costs $83.88 USD. These larger allowances give users more high‑speed data before any throttling would occur, making them a more cost‑effective option for heavy data users.
