A week is the usual shape: two days in Bucharest for the Palace of the Parliament, the Village Museum and the Athenaeum, then four or five across Brașov, Sibiu and Cluj-Napoca with the castle loop in between. The distances decide it more than the sights do, since Cluj-Napoca alone sits roughly 450 kilometres from the capital. Adding the Black Sea or the painted monasteries of Bucovina realistically needs a second week.

Through travel is available only during a limited window that depends on road and snow conditions. The 152-kilometre road crosses Romania's highest peaks and its high sections close for much of the year; the neighbouring Transalpina also has seasonal restrictions. Check the current status before committing a day to the drive, because a closure can create a long detour. Keep the route and weather forecast offline, since reception in mountain areas may vary with the network, device and local conditions.

Trains handle the main spine well and a car earns its keep in the mountains. Bucharest to Brașov runs about 166 kilometres by rail in roughly two and a half to four hours, which suits the classic first leg. The castle loop around Bran, Râșnov and Peleș, the Transfăgărășan and the Apuseni are far easier by road, while Brașov to Sibiu is slow by direct train. Decide per leg rather than for the whole trip.

They serve different days. Brașov puts the castle circuit within reach, with Bran, Râșnov and Peleș at Sinaia on one loop and the ski areas of Poiana Brașov and the Prahova Valley close by. Sibiu is the quieter historic centre and the northern gateway to the Transfăgărășan, with the ASTRA open-air museum on its edge. The two sit about 148 kilometres apart, roughly two and a half to three hours by road, so many itineraries simply use both.

Coastal resorts reach peak activity in summer. Constanța has a port and old town, Mamaia is a main resort strip, and Vama Veche lies near the Bulgarian border. The warm season runs roughly from mid-June to early September and resorts are quieter outside it; check accommodation and transport for your dates rather than assuming year-round operation. The Danube Delta north of the resorts suits boat trips, so plan that part around the actual access route and booked sailings.

Only when the country on the far side is printed on the plan's own destination list. The Danube bridge at Giurgiu carries road and rail into Bulgaria and is the usual way onward to Veliko Tarnovo, Sofia or Varna, while western routes cross to Hungary through Oradea or Arad. At each crossing the phone leaves one national network and looks for another, so read the list rather than the heading, and compare a regional package against separate country plans before setting off.

Find Wi-Fi first, in the terminal or at the accommodation, and open the setup guide that came with the plan rather than a general one. The two things to verify are that the Romania profile is enabled and that it is the line assigned to mobile data; after that, follow the plan's own sequence for roaming, network selection and APN exactly as written. Restarting or using airplane mode helps only where that guide calls for it. Keep the profile in place if none of it works, and send support the order reference, the handset model and a screenshot of the mobile-data screen.
