ESIMFUN does not provide any truly unlimited data eSIM plans for Bulgaria. All of the plans listed under its “unlimited” banner actually grant a fixed high‑speed data allowance of 100 GB, which remains available for the designated validity period (3, 5, 7, 10, 15, or 30 days). Once that 100 GB has been used, traffic is typically throttled, although the dataset does not specify the reduced speed. Travelers who need more data can instead opt for other fixed‑data plans offered by ESIMFUN; for example, the 5‑day plan provides 100 GB for $22.72 USD, and the 15‑day plan offers the same data for $65.06 USD, which may be more cost‑effective unless extremely heavy data usage is anticipated.
ESIMFUN does not provide Bulgaria eSIM plans that include a phone number or SMS capability. The provider only offers data‑only eSIMs for that country. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without needing a local phone number or SMS service.
ESIMFUN offers 30 multi‑country eSIM plans that include Bulgaria and no single‑country options. Within those 30 plans there are two types: 10 daily data cap plans, where a new daily limit is applied, and 20 fixed data cap plans that provide a set amount of data for the full validity period. Prices range from about $3.13 to $208.52, covering data caps between 1 GB and 100 GB, while validity periods range from 1 day to 30 days.
