MobileSIM eSIM Data Plans for Bulgaria

MobileSIM does not provide a true unlimited‑data eSIM for Bulgaria. The plans listed for Bulgaria are fixed‑data plans, each with a hard data cap. For example, the “Bulgaria 20 GB for 30 days” plan offers 20 GB of high‑speed data for 30 days, and the “Bulgaria Unlimited data for 30 days” plan supplies 3 GB per day (90 GB total) for 30 days before speed is throttled to 1000 kbps. These fixed‑data options are typically more cost‑effective unless a traveler requires unlimited data usage.

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.
