MobileSIM eSIM Data Plans for Sri Lanka

MobileSIM does not offer a truly unlimited high‑speed data plan for Sri Lanka. The plans advertised as “Asia Unlimited” give a daily allowance of 3GB and, once that limit is reached, data speed is throttled to 1000 kbps; therefore they are not unlimited in the usual sense.

Instead, MobileSIM provides various fixed‑data eSIMs that cover Sri Lanka. For example, the Sri Lanka 20 GB plan is valid for 30 days and costs $18 USD, the 50 GB plan is available for 90 days at $69 USD, and the 100 GB plan is valid for 180 days at $89 USD. These fixed‑data options may be more economical unless a user requires a very high volume of unthrottled traffic.

MobileSIM does not provide Sri Lanka eSIM plans that include a phone number or SMS capability. All of its available plans for Sri Lanka are data‑only, with no inbound or outbound voice or text services included. Travelers who need to communicate can use VoIP applications such as WhatsApp, Telegram, or iMessage on the data connection, but the eSIM itself does not assign a local phone number.

MobileSIM provides both single‑country and multi‑country eSIM data plans for Sri Lanka. The catalogue offers six single‑country plans and twenty‑two multi‑country plans. Across their product range the prices vary from about one and a half dollars up to about eighty‑nine dollars, while data caps span from 200 MB to a full 100 GB. Plans are available with either a fixed data allowance (for the duration of the validity) or a daily data cap that resets each day. The validity period of the plans ranges from three days to six months.
