AdventureSIMs eSIM Data Plans for Bulgaria

AdventureSIMs does not provide an unlimited data eSIM plan for Bulgaria. All of the Bulgaria‑covered plans listed by the provider have a fixed data cap, with the largest offering 100GB for 180 days at $100.64 USD. Other examples include 50GB for 90 days priced at $48.16 USD and 50GB for 30 or 180 days costing $50.32 or $53.91 USD respectively, as well as a 20GB for 30 days plan at $19.40 USD.

Choosing a fixed‑data plan can be more cost‑effective unless a traveler is an extremely heavy data consumer. For instance, the 100GB 180‑day option delivers a generous allowance and priority 5G coverage across Bulgaria and 34 additional European countries, while smaller plans such as the 50GB 90‑day plan give a lower price for moderate 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 currently provides no single‑country data plans for Bulgaria. The catalog includes 34 multi‑country plans that cover Bulgaria among other destinations. These plans span a price range from $1.43 to $100.64 and data caps from 500 MB to 100 GB, with validity periods that can be as short as one day or extend up to 180 days. Several of the multi‑country options also allow tethering.
