Stellar eSim does not provide a true unlimited data eSIM for Bulgaria. All of the listed plans that use the word “Unlimited” have a hard data cap of 3 GB, and other available plans are fixed data bundles ranging from 2 GB up to 50 GB.
If you need more data, you can choose a fixed‑data plan such as the 50 GB 15‑day bundle or the 100 GB 60‑ or 180‑day packages that are available for Bulgaria. These options give you a larger data allowance, and because they are fixed‑data plans they can be more cost effective than a high‑priced “unlimited” name would suggest.
