ByteSIM eSIM Data Plans for Sri Lanka

ByteSIM does not provide a truly unlimited data eSIM for Sri Lanka. The plans that include “Unlimited” in the name deliver 1 GB per day and after that amount the speed is reduced to 10240 kbps. For travelers who need high‑speed data without time limits, ByteSIM offers fixed‑data plans instead. For example, a 50 GB data pack is available for 30 days at $99.00 USD, and a 20 GB plan for the same period costs $48.90 USD. These fixed‑data options can be a more cost‑effective choice unless one is an extremely heavy data user.

ByteSIM does not provide any Sri Lanka eSIM plan that includes a phone number or SMS capability. All of its Sri Lanka eSIMs are data‑only, so travelers rely on the data connection for voice and messaging through VoIP applications such as WhatsApp, Telegram, or iMessage.

ByteSIM currently offers 35 single-country data plans specifically for Sri Lanka. These plans range in price from approximately $4.50 to $99.90 and include data allowances from 500MB up to 50GB. ByteSIM also provides plans with either a fixed data cap or a daily data cap, with 28 plans offering a daily allowance and 7 offering a set amount of data. Tethering is permitted on some plans, and speeds may be reduced after reaching a certain data usage threshold. No multi-country plans covering Sri Lanka are available from this provider.
