GIGAGO does not offer eSIM plans for Kazakhstan that include a phone number or SMS capability. All GIGAGO eSIMs valid in Kazakhstan are data‑only subscriptions without voice or text messaging services.
Travelers who need to stay in touch can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. These services generally work without a local phone number, but some destinations may restrict access to certain apps. It is advisable to confirm that the messaging and calling apps you rely on are available in Kazakhstan before purchasing a plan.
