MobileSIM eSIM Data Plans for Bulgaria

MobileSIM does not provide a truly unlimited data eSIM plan for Bulgaria. The plans that carry the “Unlimited” designation in their names actually offer a fixed‑allowance package of 3 GB per day, with no additional high‑speed data once that daily limit is reached; after the limit, the speed is throttled to 1000 kbps.

Travelers who need more data can choose from a range of fixed data plans instead. For example, a 20 GB plan is available for 30 days at $20.00 USD, and a 10 GB plan for the same validity period costs $13.00 USD. These plans provide a higher total data allowance and maintain high‑speed 4G/5G connectivity for the full validity without the reduction to lower speeds after a daily cap.

MobileSIM does not offer an eSIM with a local phone number or SMS capability for Bulgaria. The provider’s Bulgaria plans are data‑only, so travelers cannot receive or send SMS through the device’s native messaging app.

Users can still stay connected and communicate by using internet‑based services. Popular VoIP applications such as WhatsApp, Telegram, and iMessage work over the data connection and allow voice calls and text messages without a traditional phone number.

MobileSIM currently offers six single‑country plans and fourteen multi‑country plans for Bulgaria, providing a broad selection for travelers. The price range spans from $1.00 to $80.00, while data caps vary from 500 MB to 50 GB. Among the plans, six feature a daily data cap that resets each day, allowing for short daily bursts of data, whereas fourteen plans have a fixed data cap that remains constant throughout the validity period, giving users a steady data budget for the duration of the plan.
