BNESIM does not provide a true unlimited data eSIM for Sri Lanka. The only plan that bears the word “Unlimited” in its name offers a fixed 3 GB per day at full speed and then throttles traffic to 1 Mbps; the data allowance is still bounded.
Travelers who need a larger data supply can choose from BNESIM’s fixed‑data plans. For example, the Surf 100 GB in Sri Lanka plan provides 100 GB for 30 days, and the Surf 100 GB in Sri Lanka (No expiry) offers 100 GB without a validity period. These fixed bundles give higher amounts of high‑speed data than the limited‑daily plan and may be more cost‑effective for most users.
