JamboSim eSIM Data Plans for Bulgaria

JamboSim does not provide a truly unlimited high‑speed data eSIM for Bulgaria. The plans that carry “Unlimited” in the title give a daily cap of 3 GB; once the limit of 3 GB per day is reached, speed is reduced to 1000 kbps.
Travelers who need more data can opt for fixed‑data plans. For example, the 50 GB / 30 days plan and the 100 GB / 180 days plan are available for Bulgaria and offer larger data allowances without the daily 3 GB restriction, which can be more economical for heavy‑usage users.

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 12 single‑country data plans and 44 multi‑country data plans that include Bulgaria. Prices range from $1.99 to $188.99, with data caps spanning 500 MB to 100 GB. Some plans provide a fixed data amount for the entire validity period, while others impose a daily data limit; many also allow tethering and a reduced speed option of 1 Gbps.
