Simology eSIM Data Plans for Sri Lanka

Simology does not provide a truly unlimited data eSIM for Sri Lanka. All plans that have “Unlimited” in the name actually offer 1GB per day at full speed, with the network throttling to 1 Mbps after the daily allotment is used. For travelers who want more data without a daily limit, Simology offers fixed‑data plans such as the 50 GB plan for 30 days, which allows continuous high‑speed access for the full allowance. These fixed‑data plans can be more cost‑effective unless a user requires a very high daily data allowance.

Simology does not provide an eSIM for Sri Lanka that includes a local phone number or SMS capability. Travelers can only purchase a data‑only eSIM plan from this provider. However, callers usually can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging. Some destinations may restrict access to specific apps or VoIP services, so it is advisable to confirm that the applications you rely on are available in Sri Lanka before completing a purchase.

Simology offers 13 single‑country plans and 13 multi‑country plans for Sri Lanka. The available plans span a price range from $3.48 to $87.16 and provide data caps between 1 GB and 50 GB, with validity periods of 3 to 30 days. Some plans are fixed data bundles, offering a set amount of data for the entire validity period, while others use a daily data cap, allowing a specified amount of data each day until the plan expires. Both tethering and reduced speed considerations apply to certain plans, with reduced speed capped at 1000 Kbps.
