RedSim eSIM Data Plans for Sri Lanka

RedSim does not provide a truly unlimited data eSIM for Sri Lanka. Their “Asia Unlimited” plans give high‑speed data up to 3GB per day; once that daily limit is reached the speed drops to 1 Mbps for the remainder of the day.

Travelers looking for larger data allowances can choose from fixed‑data alternatives such as the Sri Lanka 50GB 30 Days plan or the Asia 50GB 30 Days plan, which offer 50 GB of high‑speed data to be used within a 30‑day validity period. These fixed data plans can be more cost‑effective for most users.

RedSim does not provide Sri Lanka eSIMs that include a local phone number or SMS capability. Only data‑only eSIM plans are offered for Sri Lanka. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages, but some destinations may block or restrict certain apps, so users should verify that their preferred services will work in Sri Lanka before purchasing.

RedSim provides 26 single‑country data plans for Sri Lanka and 17 multi‑country plans that include Sri Lanka in their coverage. The plans cover a price range from about $2.42 to $301.20, data caps from 1 GB up to 50 GB, and validity periods between 1 and 60 days. Some plans offer a fixed data allowance, while others limit the daily data usage before the overall cap is reached.
