Roamingo does not offer an unlimited data eSIM for Bulgaria. All of its plans for this destination are fixed‑data packages, with the highest offering 20GB for 30 days and another popular choice being 10GB for 30 days.
The plan titled “Europe Unlimited for 1 day” is available in Roamingo’s catalog, but it is limited to 2GB of high‑speed data and is therefore not truly unlimited; after the 2GB threshold is reached, the speed would be reduced (the exact throttled speed is not specified). For travelers who need more capacity, the fixed‑data options listed above are the only available alternatives.
