ZenSim eSIM Data Plans for Bulgaria

ZenSim does not provide a truly unlimited data eSIM for Bulgaria. The plans that carry the word “Unlimited” in their names actually offer a daily high‑speed allowance of 3 GB per day, after which the speed is reduced. For travelers who need a larger amount of high‑speed data or who do not want the daily cap, ZenSim sells fixed data plans in Bulgaria, such as the 20 GB plans that are valid for 10 days or 30 days. These fixed‑data options can be more cost‑effective unless the user requires a very large daily data allowance.

ZenSim does not provide eSIM plans for Bulgaria that include a local phone number or SMS capability. All available offerings from the provider for Bulgaria are data‑only eSIMs, which do not support inbound or outbound voice calls or text messages. Travelers who need to communicate while abroad can still use popular VoIP apps such as WhatsApp, Telegram or iMessage over the data connection provided by the eSIM.

ZenSim offers 6 single‑country plans and 14 multi‑country plans for Bulgaria. The single‑country options range from about 3 GB to 20 GB of data and cost between $11.00 and $57.00, with validity periods from 10 to 30 days. The multi‑country packages are in the same data and price ranges but provide coverage across multiple destinations. Within these offerings, 2 plans use a daily data cap while 18 use a fixed data cap; several plans also allow tethering.
