ZenSim does not provide a truly unlimited highโspeed eSIM for Sri Lanka.
Its schemes that carry โUnlimitedโ in the name allow 2โฏGB of 4G/5G data each day for either 10 or 30โฏdays, 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 fixedโcap plans available: for instance, a 20โฏGB allotment valid for 10 or 30โฏdays, or a 10โฏGB plan valid for 10 or 30โฏdays. These options are priced separately and can be more cost effective for travelers who consume large amounts of data.
