AeriSIM does not offer an eSIM plan for Armenia that includes a phone number or SMS capability; only data‑only eSIMs are available for that destination. Travelers who need voice or text will need to use VoIP applications. Popular services such as WhatsApp, Telegram, and iMessage can normally operate over the data connection, but some destinations may restrict or block specific apps or VoIP services, so it is wise to check that the applications you rely on are accessible in Armenia before purchasing a plan.
