ByteSIM does not offer an Armenia eSIM that includes a local phone number or SMS capability. All ByteSIM eSIMs for Armenia are data‑only plans. Travelers need to rely on data for communications.
VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used over the data connection to make calls and send messages, but some destinations may block specific apps or VoIP services. Travelers should verify that the apps they plan to use are accessible in Armenia before purchasing a ByteSIM data plan.
