ZenSim does not offer eSIM plans for Azerbaijan that include a phone number or SMS service. Travelers who need a local number for calls or texts will need to look elsewhere or use alternative communication methods.
Only data‑only eSIMs are available from ZenSim for Azerbaijan. Voice and messaging can be performed via popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain VoIP services, so travelers should verify that the apps they rely on are accessible in Azerbaijan before purchasing a plan.
