ChillaxSIM eSIM Data Plans for Bulgaria

ChillaxSIM does not provide a true unlimited high‑speed data eSIM for Bulgaria. All available plans have a specified data cap. The largest plan listed in the dataset is 100GB for 30 days, priced at $47.90 USD, but after 100GB the speed drops to 128 kbps. A Bulgaria‑specific option is 50GB for 30 days at $51.90 USD, also subject to a reduced speed of 128 kbps once the limit is reached.

Choosing a fixed‑data plan can be more cost‑effective for most travelers. These plans give a clear price, cover 4G and 5G networks throughout Bulgaria, and allow tethering. They are suitable unless a user requires truly unlimited data, in which case a larger or combined plan may be preferable.

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 mix of single‑country and multi‑country data offerings for visitors to Bulgaria. Eleven distinct single‑country plans are available, each covering data usage exclusively in Bulgaria. In addition, there are sixty multi‑country plans that include Bulgaria as part of a broader regional package. The company’s plans vary in pricing from about $2.70 to $105.90, reflecting the differing data caps which range from 1 GB up to 100 GB. Some plans are based on fixed data limits, while others employ a daily data cap, meaning the allowance is reset each day for up to 30 days of validity. Users may also benefit from optional features such as tethering or reduced speed caps of 128 Mbps or 5120 Mbps, depending on the chosen plan.
