Rufly does not provide a truly unlimited data eSIM for Bulgaria. All of Rufly’s plans for Bulgaria are fixed‑data packages that allow 500 MB of high‑speed data per day; after the daily limit is reached the speed is reduced to 5000 kbps, and it is further throttled to 512 kbps after a total usage threshold (30–70 GB depending on the specific plan).
For travelers who want a generous data allowance, Rufly offers fixed‑data plans such as the Europe Unlimited 30 Days plan, which costs $56, lasts 30 days, and provides 500 MB per day of 4G data before the speed reduction kicks in. Similar plans with 15 days or 7 days of validity are also available, offering the same daily 500 MB allowance but at a lower price. These fixed‑data options are the alternative to a true unlimited plan.
