Best Connect eSIM does not provide eSIM plans for Bulgaria that include a local phone number or SMS capabilities. The provider offers only data‑only plans in Bulgaria, so travelers cannot receive inbound or outbound calls or SMS through the eSIM.
For voice and messaging, users may rely on popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, availability of these apps can vary, and some destinations may restrict or block certain services, so it is advisable to verify that the desired apps are accessible in Bulgaria before making a purchase.
