airdatalink does not provide a Kazakhstan eSIM that includes a phone number or SMS capability. The provider offers only data‑only eSIM plans for travelers in Kazakhstan.
Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to confirm that the apps you rely on are available in Kazakhstan before purchasing a plan.
