Simbye does not offer a true unlimited data eSIM for Bulgaria. The plans labeled “Bulgaria Unlimited” provide 2 GB per day at full speed for the stated number of days, after which the speed drops to 1 Mbps. For travelers who need more data at a fixed price, Simbye offers fixed data plans such as the 50 GB 180‑day plan or the 20 GB 30‑day plan, which provide a larger data allowance for a set validity period. These fixed plans can be more cost‑effective for most users, unless an exceptionally heavy data user is looking for an unbounded data experience.
