MTX Connect does not provide any eSIM plans for Mongolia that include a phone number or SMS capability. Travelers can only obtain data‑only eSIMs from this provider, and no outbound or inbound voice or text services are offered.
Because the plans lack a local phone number, users typically rely on Internet‑based communication through apps such as WhatsApp, Telegram or iMessage. While these applications can be used over the data connection, they may be blocked or restricted in some regions, including Mongolia. Travelers should confirm that the VoIP services they plan to use remain accessible before purchasing a data‑only eSIM from MTX Connect.
