MTX Connect does not provide Kazakhstan eSIMs that include a phone number or SMS capability. All available eSIMs from this provider for Kazakhstan are data‑only plans and do not support voice or text messaging.
Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are available in Kazakhstan before purchasing.
