AlpineSIM eSIM Data Plans for Bulgaria

AlpineSIM does not provide a true unlimited‑data eSIM for Bulgaria. The plans that carry the “Unlimited” label all contain a capped data allowance, such as 300 MB, 500 MB, up to 5 GB per day, and the speed is not maintained beyond that amount. Choosing a fixed‑data plan can be more cost‑effective for travelers who need a larger, predictable amount of high‑speed data. For example, AlpineSIM offers a 50 GB eSIM that is valid for 30 days or 180 days, both of which allow full 5G coverage in Bulgaria and can be a better option than the capped “Unlimited” packages.

AlpineSIM does not provide a Bulgarian eSIM that includes a phone number or SMS capability. The provider only offers data‑only plans for Bulgaria. Travelers can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging.

AlpineSIM lists a total of 8 single‑country data plans that cover Bulgaria, as well as 170 multi‑country plans that include Bulgaria in their coverage. The provider’s plans span a price range from $0.64 to $228.64 and offer data caps between 300 MB and 50 GB, with validity periods from 1 day to 365 days. AlpineSIM’s catalog contains both daily data‑cap options (112 plans) and fixed data‑cap options (66 plans), giving travelers flexibility depending on their data‑usage habits.
