abesteSIM offers only data‑only eSIMs for travelers visiting Bulgaria, and it does not provide a local phone number or SMS capability. The provider’s eSIM plans for Bulgaria are strictly data‑only and do not support inbound or outbound calls or text messages.
Travelers who need to communicate can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict particular apps or VoIP services, so users should verify that the apps they rely on are accessible in Bulgaria before purchasing an abesteSIM plan.
