Stellar eSim does not provide a data plan for Azerbaijan that includes a phone number or SMS capability. The available eSIM option is data‑only, so travelers will not receive a local or virtual phone number and cannot send or receive SMS through the eSIM. However, with the data connection you can use VoIP applications such as WhatsApp, Telegram, or iMessage for voice calls and messaging. Availability of these services can vary, so it is advisable to check that the apps your communication relies on work in Azerbaijan before proceeding with the purchase.
