MTX Connect does not provide eSIM plans for Estonia that include a phone number or SMS capability. Travelers can only obtain data‑only eSIMs from the provider for use in Estonia.
If a phone number or SMS is needed, users may rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though availability of these services can vary by destination. It is advisable to check that the specific apps you intend to use are accessible in Estonia before purchasing an MTX Connect eSIM.
