RoameSIM eSIM Data Plans for Sri Lanka

RoameSIM does not offer a true unlimited data eSIM for Sri Lanka. All plans bearing the name “Unlimited” provide a maximum of 3 GB of high‑speed data per day; once the daily limit is reached the speed is throttled to 1000 kbps. For example, the “Asia – Unlimited – 30 days” plan costs $102.90 USD and delivers 3 GB/day for 30 days with a reduced speed of 1000 kbps after the limit is met.

Instead, travelers can choose high‑cap fixed‑data plans that may be more cost‑effective unless an extremely heavy daily data user. The 100 GB plan for 180 days costs $124.60 USD, and the 50 GB plan for 90 days costs $96.60 USD. These large data allowances offer straightforward data limits without the speed reduction associated with the “Unlimited” plans.

RoameSIM provides a range of eSIM plans for travelers visiting Sri Lanka that include a virtual phone number and SMS capability. The available plans cover data caps from 1 GB to 20 GB, with validity periods ranging from 7 days to 365 days, and prices between $21.00 USD and $124.60 USD. Each plan is supported on 5G networks and offers full roaming coverage across Sri Lanka and 164 additional countries.

The telephony service for these plans uses the dialing code +1, which is a U.S./Canada number rather than a local Sri Lankan number. The voice functionality allows both inbound and outbound calls, and the SMS feature permits sending and receiving text messages. Travelers who need specific call or messaging arrangements should consult RoameSIM directly for confirmation.

RoameSIM offers 6 single‑country plans that cover only Sri Lanka, and 34 multi‑country plans that include Sri Lanka among other destinations. The plans range in price from about $2.40 to $208.60 and in data allowance from 200 MB up to 100 GB. Among the offerings, 6 are organised as daily data caps—each plan limits the amount of data available on a per‑day basis—while the remaining 34 are fixed data cap plans, providing a set total amount of data for the validity period. This gives customers a wide variety of options tailored to short‑term or longer‑term needs.
