ZenSim eSIM Data Plans for Sri Lanka

ZenSim does not provide a truly unlimited data eSIM plan for Sri Lanka. The plans listed under “Sri Lanka Unlimited STANDARD” allocate 3 GB per day for the duration of the validity period, after which the speed may be reduced; they are not unlimited in the sense of high‑speed data without a cap.

Travelers who need a larger data allowance can choose from ZenSim’s fixed‑data plans, such as the 20 GB plan valid for 10 or 30 days (priced at $27.00 USD and $30.00 USD respectively) or the 10 GB plan for 10 days ($17.00 USD). These options offer more data than the daily allocations and can be more cost‑effective for most users.

ZenSim does not offer a Sri Lanka eSIM that includes a local phone number or SMS capability. Only data‑only eSIM plans are available for Sri Lanka. Travelers can still use popular VoIP applications such as WhatsApp, Telegram and iMessage over the data connection to make voice calls and send messages without a traditional phone number or SMS service.

ZenSim offers a total of 16 data plans for Sri Lanka, split evenly between single‑country and multi‑country options with 8 plans in each category. The available plans vary in price from roughly $11 to $70 USD and provide data caps ranging from 3 GB to 20 GB, while validity spans 10 to 30 days. Within these, 12 plans have a fixed data cap for the full period, whereas 4 plans impose a daily data cap that limits usage each day. Some of the plans also allow tethering.
