MTX Connect does not provide a Cambodia eSIM that includes a phone number or SMS capability. Travelers who need a data connection can purchase a data‑only eSIM from MTX Connect, and using VoIP applications such as WhatsApp, Telegram, or iMessage can allow voice and messaging over the data link. However, some destinations may block or restrict access to specific apps or VoIP services, so travelers should confirm that these applications are usable in Cambodia before purchasing.
