simpleSIM does not provide a truly unlimited data eSIM for Sri Lanka. The plans that carry the word “Unlimited” in their names actually offer a fixed data allowance of 1 GB per day or 3 GB per day, and once that amount is reached the speed is throttled to 512 kbps or 1 000 kbps. Therefore, these plans are not unlimited in the sense of offering high‑speed data without limits.
Travelers who need a larger data allowance can choose from simpleSIM’s fixed data plans. For example, the eSIM Sri Lanka 20 GB plan gives 20 GB for 30 days, and the eSIM Asia 50 GB plan provides 50 GB for 90 days. These fixed data plans may be more cost‑effective for users who consume a lot of data.
