Kolet does not offer data‑only Estonian eSIM plans that include a phone number or SMS capability. Travelers who need a local phone number or the ability to send SMS messages will need to look elsewhere for a plan that provides those services.
With Kolet’s data‑only eSIM, users can still access VoIP applications such as WhatsApp, Telegram and iMessage through the internet connection to make calls and send messages, although some destinations may block or restrict certain apps. Therefore, if a phone number or SMS is essential, it is recommended to verify the availability of the required services in Estonia before purchasing a Kolet plan.
