TailSim eSIM Data Plans for Sri Lanka

TailSim does not provide a truly unlimited data eSIM for Sri Lanka.
The plans that include “Unlimited” in their name actually deliver 2 GB per day and the network speed drops to 512 kbps after that limit is reached. Travelers seeking higher capacity may choose from TailSim’s fixed data options, such as the 50 GB plan valid for 30 days or the 20 GB plan also valid for 30 days, which offer larger data allowances without the post‑limit throttling that applies to the “Unlimited”‑named plans.

TailSim does not provide an eSIM for Sri Lanka that includes a phone number or SMS capability. The provider offers only data‑only plans for this destination.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are available in Sri Lanka before purchasing a plan.

TailSim offers 14 single‑country data plans for Sri Lanka and does not provide any multi‑country options. Among these plans, 8 have a daily‑data‑cap structure while 6 are fixed‑data packages. Prices for Sri Lanka plans range from $3.99 to $94.50, with data limits spanning 1 GB to 50 GB and validity periods between 3 and 30 days.
