JamboSim eSIM Data Plans for Bulgaria

JamboSim does not provide a truly unlimited high‑speed data plan for Bulgaria. All plans that carry the word “Unlimited” still contain a data cap of 3GB per day; once that limit is reached the speed is reduced to 1000 kbps. Travelers who need more data can choose from fixed‑data plans, such as the 100 GB plan for 180 days priced at $195.99 USD or the 50 GB plan for 30 days priced at $47.99 USD. These fixed information plans are usually more cost effective for users who do not rely on very high‑speed data throughout their trip.

JamboSim does not provide eSIM plans that include a phone number or SMS capability for Bulgaria; only data‑only eSIMs are available from this provider.
Travelers who need to make or receive calls and send messages can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Bulgaria before purchasing a plan.

JamboSim provides 12 single‑country eSIM data plans that are available for Bulgaria and 93 multi‑country eSIM data plans that include Bulgaria. Across all offerings the price ranges vary from $0.99 to $196.99, while the data caps span from 300 MB to 100 GB. The plans are offered in both fixed data‑amount and daily‑data‑cap formats, allowing customers to choose either a set amount of data for the duration of the plan or a daily limit that can be used each day.
