MobileSIM eSIM Data Plans for Bulgaria

MobileSIM does not offer a truly unlimited high‑speed eSIM plan for Bulgaria. The plans labeled “Unlimited” actually provide 3 GB per day and, after that daily limit is reached, the speed is throttled to 1000 kbps. Travelers who need uninterrupted high‑speed data can choose MobileSIM’s fixed‑data plans, such as 20 GB for 30 days at $20.00 USD or 10 GB for 30 days at $12.00 USD. These fixed plans offer larger total data allowances without the daily throttling that applies to the “Unlimited” plans and can be more cost‑effective for most users, while the “Unlimited” plans may suit very heavy data consumers who value longer flexibility.

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 offers 12 single‑country data plans for Bulgaria. All of those plans are either a fixed data amount or a daily data cap. The available tariffs vary from about $4.00 to $72.00, covering data balances between 1 GB and 20 GB over validity periods of 3 to 30 days. There are no multi‑country plans available for Bulgaria.
