JamboSim eSIM Data Plans for Sri Lanka

JamboSim does not provide a truly unlimited data eSIM for Sri Lanka. The plans that carry the “Unlimited” name actually offer 3 GB of high‑speed data per day; after the daily 3 GB is reached the speed is reduced to 1000 kbps. For travelers who need more data without the daily limit, JamboSim sells fixed‑data plans instead. Example options include the eSIM JamboSim Asia 20 GB / 30 days for $10.99 USD and the eSIM JamboSim Asia 100 GB / 180 days for $69.99 USD. Selecting a fixed‑data plan can be more cost‑effective for heavy data users compared with the capped unlimited‑styled offers.

Yes, JamboSim sells eSIMs for Sri Lanka that include a phone number and allow SMS. The available plans range from 1GB for 7 days at $11.99 USD up to 20GB for 365 days at $101.99 USD. All of these plans use a dialing code of +1, which is a North American number, and they support outbound voice calls and outbound SMS only, meaning you can make calls and send texts, but cannot receive them. Travelers who need specific call or text capabilities should confirm the details directly with JamboSim.

JamboSim provides 6 single‑country data plans and 33 multi‑country data plans that include coverage for Sri Lanka. The available plans span a price range from roughly $1.99 to $99.99 and data caps from 200 MB to 100 GB. Within the single‑country options users can choose between fixed‑data plans, where the allotted data remains constant for the entire validity period, and daily‑cap plans, where the data allowance resets each day. The multi‑country catalogue likewise offers a combination of fixed‑data packages that maintain a consistent data amount across their validity and daily‑cap packages that refresh daily.
