eSIMsData does not provide an actual unlimited‑data eSIM for Sri Lanka. All of its plans contain a hard data cap, even those that use “Unlimited” in the name; the data allowance is limited to a fixed amount per day and, once reached, the speed is reduced (1250 kbps for the “Essential” plans and 2000 kbps for the “Plus” plans).
For travelers who want a large data allotment, eSIMsData offers fixed data plans such as the Sri Lanka 100GB 30 Days plan, which supplies 100GB of high‑speed data for 30 days. These fixed data plans can be more cost‑effective for high‑usage trips compared to the “Unlimited” plans that still impose daily caps.
