JamboSim eSIM Data Plans for Sri Lanka

JamboSim does not provide a truly unlimited data eSIM for Sri Lanka. All of its plans for the country have a fixed data allowance that must be used within a specified validity period. For example, the “eSIM JamboSim Asia 100GB / 180 Days” plan offers 100GB of high‑speed data that must be consumed within 180 days, and the “eSIM JamboSim Asia 50GB / 7 Days” plan gives 50GB that must be used in seven days.

If a traveler needs a large amount of data, they can choose one of these fixed‑data plans. The 100GB / 180 days plan is the largest single bundle available, while the 50GB / 7 days plan provides a high daily data rate for a short period. These options are more cost‑effective for most users than a plan that would throttle speed after a daily limit, as the throttled speed is only 1 Mbps after the daily 3 GB limit is reached.

Yes, JamboSim sells Sri Lanka data plans that include a phone number and SMS functionality. The available plans range from 1GB for 7 days to 20GB for 365 days and are priced between $11.99 USD and $105.99 USD. Each plan supplies a phone number with the dialing code +1, allowing outbound calls and outbound SMS messages; inbound voice and SMS are not supported. The numbering is a US-based phone number rather than a local Sri Lankan number. Travelers who need specific call or messaging features should verify the details directly with JamboSim before purchasing.

JamboSim offers 6 single‑country data plans and 40 multi‑country plans for Sri Lanka. The plans come in two varieties: 6 daily‑data‑cap options and 40 fixed‑data‑cap options. Prices range from about $1.99 to $105.99, while data caps span from 200 MB up to 100 GB, giving travelers a wide spectrum of choices to fit different budgets and usage needs.
