ByteSIM does not provide a truly unlimited high‑speed data eSIM for Sri Lanka. Their plans that include “Unlimited” in the name actually offer 1GB per day, after which the connection speed is reduced to 10240 kbps. Because of this daily data cap, the plans are not unlimited in the sense of providing high‑speed data without restrictions.
If a traveler needs a larger data allowance without daily limits, ByteSIM offers fixed‑data options such as 50 GB for 30 days or 20 GB for 30 days. These plans give a set amount of high‑speed data over the validity period and may be more cost‑effective for users who keep within the allocated data.
