RedSim does not provide a true unlimited data eSIM for Romania. The plans that include “Unlimited” in their name, such as Romania Unlimited 3 Days or Romania Unlimited 30 Days, actually offer high‑speed data up to 3 GB per day (or 5 GB per day for the 41‑country version) and then drop the speed to 1 Mbps for the remainder of the day, so they have a hard data limit. If you need a larger uninterrupted data allowance, RedSim’s fixed data plans might be more suitable. For example, a 20 GB 30‑day plan or a 50 GB 30‑day plan give a fixed amount of high‑speed data for the entire validity period and can be a cost‑effective option for heavy data usage.
