eSIM for Romania — Instant 4G/5G Data Plans

Romania's mobile network is served by four main operators: Orange Romania, Vodafone Romania, Telekom Romania Mobile, and Digi Mobil. 4G LTE coverage is comprehensive across Bucharest, Cluj-Napoca, Timisoara, Brasov, and all major cities, with strong connectivity along main motorway and rail corridors. The Carpathian mountain resorts including Sinaia, Predeal, and Poiana Brasov have reliable coverage in resort areas, with signal weakening on higher ski runs and remote ridgeline hiking routes. The Danube Delta has coverage in Tulcea and main village areas, with signal varying on delta waterways and remote channels. Rural areas of Moldova and some eastern regions may have weaker signal in isolated zones. MobiSIM connects through supported Romanian networks to deliver reliable data across the country's main cities and tourist destinations.

Activate your MobiSIM eSIM before landing at Henri Coandă International Airport in Bucharest or your arrival city so you are connected from the start. Download offline maps for Brasov, the Transfăgărășan Highway, Bucovina monastery circuit, and the Danube Delta water channels before departing major cities, as mountain and delta terrain can have inconsistent signal. Keep your home SIM active for calls while MobiSIM handles your data. Bucharest has a well-developed metro system and having live data for STB transport apps and navigation makes getting around the city straightforward from arrival. If you are driving the Transfăgărășan mountain road, hiking in the Bucegi or Fagaras ranges, or exploring remote Danube Delta channels by boat, save all maps, accommodation details, and emergency contacts offline before setting out.
