MobileSIM eSIM Data Plans for Bulgaria

MobileSIM does not provide a truly unlimited data eSIM for Bulgaria.
Plans that carry “Unlimited” in the name, such as the Bulgaria Unlimited data for 3–30 days, actually give a fixed high‑speed allowance of 3 GB per day. After that daily limit is reached the speed is reduced to 1000 kbps. For travelers who need a larger constant data supply, MobileSIM offers fixed‑data plans, for example 20 GB for 30 days at $20.00 USD or 10 GB for 30 days at $12.00 USD, which may be more cost‑effective for heavy users.

MobileSIM does not provide an eSIM plan with a local phone number or SMS capability for Bulgaria. Only data‑only eSIMs are offered by the provider. Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but they should check that these apps are functional in Bulgaria before purchasing, as some destinations may restrict access.

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.
