MobileSIM eSIM Data Plans for Bulgaria

MobileSIM does not offer a truly unlimited data eSIM for Bulgaria. Plans that contain the word “Unlimited” are capped at 3 GB per day; once the limit is reached, the connection is throttled to 1000 kbps.

Travelers who need larger data allowances can choose from a variety of fixed‑data plans. For example, MobileSIM sells a 20 GB plan for Bulgaria that is valid for 30 days, as well as a 10 GB plan for the same duration. Other large‑cap options include a 50 GB plan that covers Bulgaria and the neighbouring 41 countries, and a 20 GB plan that is also available for Bulgaria only. These fixed‑data packages provide a cost‑effective alternative for users who do not require unrestricted high‑speed data.

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 that include coverage in Bulgaria. Pricing for the available bundles ranges from about one dollar to roughly ninety‑nine dollars, and data allowances span from 500 megabytes up to 50 gigabytes. Some of the plans provide a fixed data amount for the entire validity period, while others apply a daily data cap that limits usage each day. Validity periods for all plans run from three to thirty days.
