WonderConnect does not provide eSIM plans for Azerbaijan that include a phone number or SMS capability.
Travelers can only purchase data‑only eSIMs through WonderConnect. Over the data connection, VoIP services such as WhatsApp, Telegram and iMessage can usually be used for calls and messaging, but some destinations may block or restrict specific apps, so it is advisable to confirm that the services you depend on are accessible in Azerbaijan before buying.
