MobiMatter does not provide a Kazakhstan eSIM that includes a phone number or SMS capability. The available plans are strictly data‑only, meaning travelers will not receive an active local number or the ability to send or receive standard SMS text messages.
Users who need voice or text communications can still rely on internet‑based services such as WhatsApp, Telegram or iMessage through the data connection. However, because some destinations may restrict or block particular VoIP applications, travelers should confirm that the apps they plan to use are accessible in Kazakhstan before purchasing an eSIM.
