Airalo eSIM Data Plans for Bulgaria

Airalo does not offer a truly unlimited eSIM plan for Bulgaria. All of the plans labelled “Unlimited” in the Airalo catalogue have a hard cap of 3GB per day; after this amount the connection speed is reduced to 1000kbps. For travelers who need more data, Airalo provides fixed data plans with larger allowances, such as the 100GB plan valid for 180 days or the 50GB plans with 30‑day validity. These fixed plans offer a higher data volume within a set validity period and may be more suitable for heavy users.

Airalo does not offer eSIMs for Bulgaria that include a phone number or SMS capability; only data‑only plans are available. Travelers who need messaging or voice services can use VoIP apps such as WhatsApp, Telegram or iMessage over the data connection, but some destinations may restrict these services, so it is advisable to confirm that the required apps are accessible in Bulgaria before buying an eSIM.

Airalo offers 18 single‑country plans and 58 multi‑country plans for Bulgaria. The single‑country selections give a set amount of data (fixed data cap) that can be used continuously for the validity period, while the multi‑country plans include roaming across several destinations using the same data pool. In addition, the same quantity of options exist in a daily‑data‑cap format, allowing a limited amount of data to be used each day within the validity window. Across all plans the prices range from about $4.00 to $185.00, the data limits span from 1 GB up to 100 GB, and the validity periods cover 3 days up to 365 days.
