Kolet does not provide eSIM plans for Sri Lanka that include a local phone number or SMS capability. Travelers who purchase a Kolet eSIM for Sri Lanka will receive a data‑only plan, which allows internet access but does not support inbound or outbound voice calls or text messages. Popular VoIP applications such as WhatsApp, Telegram, or iMessage can usually be used over the data connection for calls and messaging, but access to these services can depend on local restrictions, so it is advisable to confirm that the apps needed are available and functional in Sri Lanka before purchasing.
