The ETravelSim Romania eSIM runs on Vodafone Romania, one of the country's three major mobile networks alongside Orange Romania (the largest) and Digi Mobil (RCS). Vodafone is independently rated as particularly strong in the Danube Delta and Carpathian regions per 2026 reviews — useful for travellers heading to Transylvania, Maramureș, or the Delta. For pure city travel, all three Romanian networks deliver comparable urban performance, but Vodafone's mountain reach is the genuine selling point on this plan.
