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.
