eSIMX does not offer an eSIM plan for Kazakhstan that includes a phone number or SMS capability. The only eSIMs available from eSIMX for Kazakhstan are data‑only plans. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict access to certain apps, so it is advisable to check that the services you require are accessible in Kazakhstan before purchasing.
