ChillaxSIM eSIM Data Plans for Bulgaria

ChillaxSIM does not provide a truly unlimited high‑speed data plan for travelers in Bulgaria. The plans listed under the “unlimited” heading all contain a 1 GB data allowance; after this limit is reached the speed is throttled to 5120 kbps. For visitors who need a larger quantity of data, ChillaxSIM offers fixed‑data options such as the 50 GB plan valid for 30 days, which remains available at higher speeds until the cap is reached, after which the speed drops to 128 kbps. Selecting a fixed‑data plan can be more cost‑effective for most users, unless they anticipate consuming data beyond the 1 GB limit.

ChillaxSIM does not offer a Bulgaria eSIM plan that includes a phone number or SMS functionality. The only option available from the provider is a data‑only eSIM. Travelers can still communicate using VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection, but they will not have a traditional Bulgarian phone number or the ability to send or receive SMS messages.

ChillaxSIM provides a range of plans that include Bulgaria, including both single‑country options and multi‑country packages. In Bulgaria there are 11 single‑country plans and 59 multi‑country plans that feature Bulgarian coverage. The available plans run from 1 GB to 100 GB of data and cost between approximately $2.70 and $105.90 depending on validity, which can be as short as one day or as long as 30 days. Some of the plans are sold as fixed data packages, giving the buyer a set amount of data for the entire validity period, while others are daily data cap plans that reset each day and may allow a smaller daily allotment that accumulates over the validity period.
