Best eSIM for Romania

Romania is a driving country. The classic trip lands at Henri Coandă (OTP) in Bucharest, picks up a car and heads for Brașov, Sibiu, Sighișoara and the Transfăgărășan, and almost none of that is done without a map open on the dashboard. The mountain roads change condition by season and the diversions are not always signposted in a language you read. Add the castles, the painted monasteries of Bucovina and a night in a guesthouse booked through an app, and the phone is doing more work than in a city break. Loading a travel eSIM before you fly means the navigation is running before you reach the car hire desk, with no counter visit and no paperwork.

Plan for a week to ten days and for heavy, continuous navigation, which is the defining data pattern of a Romanian itinerary. Add translation and photograph uploads and it climbs further. If two of you are sharing directions between a phone and a tablet, confirm hotspot on the plan card. 5G is available in Bucharest, Cluj-Napoca and other large cities, and Romania has a reputation for fast fixed and mobile internet in urban areas, though on the Transfăgărășan you will be on 4G or nothing. You do not need a Romanian number; keep your home SIM in the phone for banking codes and let the eSIM carry data. If Romania is part of a run that also takes in Bulgaria, Hungary or Serbia, compare a Europe regional plan. Check your handset on the device list before buying.

Romania is served by Orange România, Vodafone România and Digi, and your eSIM connects to a partner among them and moves between them as signal dictates. Urban coverage is strong and 5G is live in the larger cities. The motorway network and the main roads through Transylvania are reliably covered. Where it drops is predictable from the map: the high sections of the Transfăgărășan and Transalpina, the forested valleys of the Apuseni, and the channels of the Danube Delta, where you should assume long stretches without a signal.

• Bucharest — dependable citywide, including the metro stations.
• Brașov and Sinaia — strong in town, weaker on the Bucegi trails above.
• Cluj-Napoca — reliable, with 5G in the centre.
• Sibiu and Sighișoara — good throughout the old towns.
• Danube Delta — patchy at best once you are among the reed channels.

For a road trip through Transylvania the eSIM wins on convenience: you drive out of the airport already navigating. EU-based travellers should check whether Romania is in their existing allowance first, since it may already be included at no extra cost.

1. Buy a plan from the grid above; the email with your QR code and install link arrives at once.
2. iPhone on iOS 17.4 or later: tap the link. Otherwise Settings, Mobile Data, Add eSIM. Android: Settings, Connections or Network, SIM manager, Add eSIM and scan.
3. Install at home on Wi-Fi and label the line Romania.
4. Enable Data Roaming for the eSIM line, and turn mobile data off on your home SIM.
5. After landing at Henri Coandă or Cluj, choose the eSIM as your data line before you collect the hire car and set the first route.
6. Validity begins at that first connection.

Install several days early on home Wi-Fi, then leave the line switched off. The plan only starts counting when the eSIM first attaches to a Romanian network, so there is no penalty for installing ahead. Keep it inactive during a connection in Vienna, Munich or Istanbul, and turn it on once you have landed, so the route to Brașov is loaded before you leave the airport car park.
