Skyalo does not provide a Kazakhstani eSIM that includes a local phone number or SMS capability. The provider offers only data‑only eSIMs for travelers in Kazakhstan. Using the data connection, you can still reach services such as WhatsApp, Telegram, and iMessage, but the availability of these VoIP applications may vary in the destination, so it is wise to confirm that the apps you want to use are accessible in Kazakhstan before buying a plan.
