No. eSIM4Travel does not provide a truly unlimited data eSIM for Sri Lanka. All plans sold for Sri Lanka have a specific data amount or a daily data limit. For example, the largest fixed‑data plans available are 50 GB/30 days and 20 GB/30 days, both of which are unthrottled during the validity period. Plans with “Unlimited” in their name, such as Unlimited‑3Days‑Sri Lanka, actually allow 3 GB per day and, after that limit, the speed is reduced to 1000kbps, so they are not truly unlimited.
