Numero eSIM does not currently offer Central Asia eSIM plans that provide a phone number or SMS capability. The provider only offers data‑only plans for destinations in Central Asia. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging, but some destinations may block or restrict specific apps or VoIP services, so it is advisable to verify that the services you rely on are accessible in Central Asia before purchasing.
