JamboSim eSIM Data Plans for Bulgaria

JamboSim does not provide a truly unlimited data eSIM for Bulgaria. All of its Bulgaria‑specific plans have a data cap of 3GB per day; after that amount is used the speed is throttled to about 1 Mbps. Travelers can select from fixed‑data plans ranging from 3 days up to 30 days, each offering 3GB per day, or larger bundles such as the 50GB or 100GB options that last longer but are still capped.

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 offers 12 single‑country data plans for Bulgaria. All of these plans are variable‑length offers with prices ranging from $1.99 to $196.99. The data caps across the Bulgaria plans span from 500 MB up to 100 GB, and the validity periods extend from 3 to 180 days. The provider’s lineup includes both fixed‑data‑cap options and daily‑data‑cap offerings, allowing customers to choose between a set amount of data for the entire validity period or a daily‑based data allowance that resets each day.
