eSIMMigo does not offer an unlimited‑data eSIM for Bulgaria. All of its Bulgarian plans have a fixed data allowance listed in the Data cap column, with the largest available bundle being 100 GB for 180 days or 80 GB for 15–25 days. These are fixed‑data plans, meaning the data must be used within the specified validity period.
If a traveler needs a large amount of data, the 100 GB 180‑day plan or the 80 GB 20‑day plan on Orange 5G can be considered. Fixed data plans are often more cost‑effective for travelers who anticipate using a substantial amount of data but not an unlimited amount, while Pay‑as‑you‑go options remain available for those who prefer to top up as needed.
