Airalo does not provide a truly unlimited data eSIM for Romania. All of its plans for the country have a fixed data allowance, such as 20GB for 15 days, 50GB for 30 or 90 days, or 100GB for 180 days. These fixed data plans give high‑speed data up to the stated limit; after the limit is reached the speed is reduced to 1 Mbps. If a traveler needs a larger data allowance, choosing one of these fixed plans can be more cost‑effective than a plan that advertises “Unlimited” but actually caps usage at 3 GB per day.
