AdventureSIMs eSIM Data Plans for Bulgaria

AdventureSIMs does not offer an unlimited data eSIM plan for Bulgaria. All available plans provide fixed data allowances.

The provider offers several fixed‑data options for travelers staying in Bulgaria. One example is the 50GB 180 days plan, priced at $43.84 USD, which includes tethering and provides 4G and 5G coverage in Bulgaria plus 33 additional countries. A smaller 20GB plan is available for 30 days at $21.92 USD or for 90 days at $23.56 USD, both allowing tethering and using the same 4G/5G network. Selecting a fixed data plan can be more cost effective for most users unless an extremely heavy data consumer needs unlimited usage.

AdventureSIMs does not offer a Bulgaria eSIM that includes a local phone number or SMS capability. All of their Bulgaria eSIM plans are data‑only, which means you can use the internet connection for services such as WhatsApp, Telegram and iMessage to make calls and send messages, but no traditional phone number or SMS service is provided.

AdventureSIMs offers 24 multi‑country eSIM plans that include Bulgaria; there are no single‑country plans for the country. The available plans are priced between $2.73 and $43.84 and provide data caps ranging from 500 MB to 50 GB with validity periods between one and 180 days. All of these plans allow tethering.
