ChillaxSIM eSIM Data Plans for Sri Lanka

ChillaxSIM does not provide a truly unlimited high‑speed eSIM plan for Sri Lanka. All plans labeled “Unlimited Data” offer a fixed 1 GB/day allowance; after the daily limit is reached the speed is throttled to 5 000 kbps. For travelers who need more data without throttling, ChillaxSIM sells fixed‑data plans such as the 20 GB for 30 days or the 10 GB for 30 days options, which provide high‑speed access until the total data cap is reached, after which the speed drops to 128 kbps. Choosing a fixed‑data plan can be more cost‑effective unless one expects very high daily usage.

ChillaxSIM does not provide Sri Lanka eSIM plans that include a local phone number or SMS capability. The provider’s offering for Sri Lanka is limited to data‑only eSIMs with no inbound or outbound voice or text services.

Travelers who need to place calls or send messages can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection on a ChillaxSIM eSIM.

ChillaxSIM currently offers 29 single coverage data plans for Sri Lanka. These plans range in price from approximately $3.50 to $84.90 and include data allowances from 1GB to 20GB. Within these options, you’ll find both fixed data plans (providing a set amount of data for the plan’s duration) and daily data cap plans (offering a certain amount of data each day). Tethering is allowed on some plans, and reduced speeds may apply after a certain data usage threshold, either at 128kbps or 5120kbps. They do not currently offer any multi-country plans that include Sri Lanka.
