No, nextSIM does not provide a truly unlimited data eSIM plan for Sri Lanka. The plans that use the word “Unlimited” in their names all have a capped data allowance, for example 1 GB in total or 1 GB per day, and after the cap is reached the speed is reduced to a throttled rate. Instead, nextSIM offers fixed data plans that give a set amount of high‑speed data over a specified validity period. Two of the larger fixed‑data options are the 100GB 30 days Standard plan, priced at $118.30 USD, and the 50GB 30 days Standard plan, priced at $67.09 USD. Other fixed plans are available with smaller daily data limits, such as 1 GB per day for 7 days or 2 GB per day for 7 days, which can be more cost‑effective for travelers who do not need a very high data volume.
