JamboSim eSIM Data Plans for Bulgaria

JamboSim does not provide a truly unlimited data eSIM for Bulgaria. The plans labeled “Unlimited” give a fixed allowance of 3 GB per day; once that limit is reached, the speed drops to 1000 kbps. Travelers who need more data can choose fixed‑data plans, such as a 100 GB plan for 180 days, a 50 GB plan for 30 or 90 days, or a 20 GB plan for 30 days. These fixed‑data options may offer a better cost‑to‑usage ratio, especially for heavy data consumers.

JamboSim does not offer an eSIM plan for Bulgaria that includes a phone number or SMS capability. Travelers can only purchase a data‑only eSIM from JamboSim for use in Bulgaria. If a phone number or traditional SMS is needed, travelers can rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and provide voice and messaging services without an on‑device number.

JamboSim offers 6 single‑country plans that cover only Bulgaria and 34 multi‑country plans that include Bulgaria, giving a total of 40 plans available for the country. The available plans range in price from $2.99 to $173.99 and in data cap from 500 MB to 100 GB. They include both daily‑cap options and fixed‑data bundles; some plans allow tethering, while others may reduce speed to 1 Mbps once the data cap is reached.
