eSimfly eSIM Data Plans for Bulgaria

eSimfly does not provide a true unlimited data eSIM for Bulgaria.
All plans labeled “Unlimited” in the eSimfly catalogue actually cap high‑speed data at 1 GB per day (or 3 GB/day for their longer “UK and EU” bundles). No plan has an unlimited data allowance, and when the cap is reached the speed is reduced, though the specific throttled rate is not listed.

Travelers who need a large steady data supply can opt for one of eSimfly’s fixed‑data plans instead. For example, a 30 GB plan valid 30 days is available for about $18.78 USD, and a 50 GB plan for the same period costs roughly $27.57 USD. These fixed‑data plans offer a more cost‑effective solution unless the user is an extremely heavy data consumer.

eSimfly does not offer a Bulgaria eSIM that includes a local phone number or SMS capability. The provider only offers data‑only eSIM plans for travelers in Bulgaria. For voice and messaging, popular VoIP apps such as WhatsApp, Telegram, and iMessage can be used over the data connection.

eSimfly offers 9 single‑country plans and 50 multi‑country plans for Bulgaria. The overall price range across these plans is approximately $1.56 to $211.15, while the data caps vary from 1 GB to 50 GB. In addition to the larger fixed data‑cap packages that provide a set amount of data for the entire validity period, the provider also offers daily‑cap plans that reset a specified data limit each day. Many of these plans allow tethering.
