ZenSim eSIM Data Plans for Sri Lanka

ZenSim currently offers eight single-country data plans for Sri Lanka. These plans range in price from $11.00 to $48.00 and include data allowances between 2GB and 20GB. Plan validity periods vary from 10 to 30 days. Within these options, you'll find both fixed data plans (offering a set amount of data for the duration of the plan) and daily data cap plans (providing a specific amount of data each day). Tethering is permitted with some of these plans. No multi-country plans covering Sri Lanka are available from this provider.

ZenSim does not provide a truly unlimited high‑speed eSIM for Sri Lanka.
Its schemes that carry “Unlimited” in the name allow 2 GB of 4G/5G data each day for either 10 or 30 days, after which the carrier may throttle speed (specific throttled rates are not listed).
Users who need a higher volume of data can choose one of the fixed‑cap plans available: for instance, a 20 GB allotment valid for 10 or 30 days, or a 10 GB plan valid for 10 or 30 days. These options are priced separately and can be more cost effective for travelers who consume large amounts of data.
