SimBalkan eSIM Data Plans for Bulgaria

SimBalkan does not offer a genuine unlimited high‑speed data eSIM for Bulgaria. All plans listed as “Unlimited” provide a daily high‑speed allowance of 3 GB, and once that limit is reached the speed is reduced to 1000 kbps. Travelers who prefer uninterrupted data might instead choose one of SimBalkan’s fixed‑data plans. For example, a 50 GB plan is available for 30 days at $43.75 USD, and a 20 GB plan for the same period costs $20.66 USD. These fixed plans provide the full data amount at normal speed throughout the validity period and can be more cost‑effective for heavy data users.

SimBalkan does not offer any Bulgaria eSIM plans that include a phone number or SMS capability. The provider only sells data‑only eSIMs for Bulgaria, so travelers cannot receive inbound calls or text messages on a local number.

For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict specific apps or VoIP services, so it is advisable to check that the applications you need are accessible in Bulgaria before purchasing a plan.

SimBalkan provides 10 single‑country data plans and 13 multi‑country plans that include Bulgaria, for a total of 23 plans available in the country. The price spectrum of these offers ranges from $2.89 to $89.92, while the data caps vary from 1 GB to 50 GB and validity periods span 3 to 30 days. Within the selection, 4 plans feature a daily data‑cap model, whereas the remaining 19 adhere to a fixed data‑cap approach, allowing travelers to choose the type that best fits their usage patterns.
