ZenSim eSIM Data Plans for Sri Lanka

ZenSim does not offer a truly unlimited high‑speed data eSIM for Sri Lanka. The plans marketed with “Unlimited” in the name limit users to 3GB of high‑speed data per day, after which the speed would be throttled.

Instead, ZenSim provides fixed‑data plans for Sri Lanka. Examples include a 20GB plan for 10 days priced at $27.00 USD and the same 20GB plan for 30 days at $30.00 USD, along with 10GB and 5GB options. These larger fixed‑amount plans may be more cost‑effective, especially for travelers who expect heavier data consumption.

ZenSim does not offer eSIM plans for Sri Lanka that include a phone number or SMS capability. The provider’s Sri Lanka offerings are limited to data‑only plans, so travelers will not receive an active number for voice or text messaging.

Customers who need to communicate can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. These apps enable voice calls and messaging without requiring a traditional phone number.

ZenSim currently lists eight single‑country data plans for Sri Lanka and has no multi‑country options for that destination. Among the plans, two feature a daily data‑cap model while the remaining six provide fixed data amounts. The available packages range from about $11 to $42 USD, include data caps between 3 GB and 20 GB, and have validity periods from 10 to 30 days, with some permits for tethering.
