Simbye does not provide eSIM plans for Kazakhstan that include a phone number or SMS capability. Travelers who choose a Simbye eSIM for Kazakhstan will only receive a data‑only plan without local voice or text services.
However, the data connection can be used with popular VoIP applications such as WhatsApp, Telegram, and iMessage to make calls and send messages. Because some destinations may block or restrict certain apps, travelers are advised to confirm that the services they rely on work in Kazakhstan before purchasing an eSIM.
