ZenSim eSIM Data Plans for Sri Lanka

ZenSim does not offer any genuinely unlimited data eSIM plan for Sri Lanka. The only plans with “Unlimited” in their name provide a fixed daily high‑speed data allotment of 3GB for either 10 or 30 days. For travelers who want a larger amount of data, ZenSim offers fixed data plans such as a 20GB plan valid for 10 days or 30 days. These fixed plans can be more cost‑effective for regular data use, while the limited‑daily‑unlimited name may suit short trips if daily usage remains within 3GB.

ZenSim does not offer a Sri Lanka eSIM that includes a local phone number or SMS capability. Only data‑only eSIM plans are available for Sri Lanka. Travelers can still use popular VoIP applications such as WhatsApp, Telegram and iMessage over the data connection to make voice calls and send messages without a traditional phone number or SMS service.

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.
