Yes. Brașov city center and the Bran Castle area have full 4G on Orange Romania, Vodafone Romania, and Telekom Romania. Orange and Vodafone deliver 5G in the old town. The Transfăgărășan mountain road and high-altitude trails lose signal — download offline maps before you drive.

Yes on platforms, no in tunnels between stations. Bucharest metro finished cell-service rollout in all stations in 2024, so your eSIM works while you wait. STB Activ requires live data to validate mobile tickets, so the eSIM is essential if you skip paper tickets.

Partially. Tulcea and the main delta towns have LTE on Telekom Romania, but the rural channels and smaller villages are 3G-only or no signal. Orange Romania and Vodafone Romania thin out fast past Tulcea. Download offline maps and expect dead zones on boat trips.

Sibiu city center has 5G on Orange Romania and Vodafone Romania. The Făgăraș Mountains hiking trails drop to 3G above 1,200 meters on all carriers, and some ridgelines have no signal. Download trail maps and weather forecasts before you hike.

Three to five gigabytes covers daily navigation, STB Activ transit tickets, Uber or Bolt rides, WhatsApp calls, and occasional Instagram. Add two gigabytes if you plan to hotspot a laptop or stream on CFR trains. Bucharest and Brașov both have café Wi-Fi, so you can offload heavy downloads.

Yes. WhatsApp voice and video calls work over the eSIM's data connection on Orange Romania, Vodafone Romania, or Telekom Romania. Quality is good in cities with 5G or LTE, but expect dropouts in the Carpathian foothills and the Danube Delta where coverage thins to 3G.

Yes. STB Activ is Bucharest's official transit app and requires live data for QR validation on metro and buses. The eSIM provides that connectivity. Paper tickets are harder to find at smaller stations, so the app is the default for most travelers.

Both deliver 5G in Cluj-Napoca's old town, university quarter, and Someșeni business district. Orange Romania has slightly better reach in the surrounding villages. Telekom Romania runs LTE. The eSIM hands off between all three, so you get the strongest tower at each location.

Neither works reliably. The Transfăgărășan mountain road has long stretches with no signal on Orange Romania, Vodafone Romania, or Telekom Romania. Download offline maps in Brașov or Sibiu before you drive. Signal returns in the valleys on both sides.

Yes, but CFR trains on the Bucharest-Brașov-Cluj route have no onboard Wi-Fi, so the eSIM is your only connectivity. Coverage is LTE in the plains and 3G in the Carpathian foothills. Tunnels between Brașov and Predeal drop signal for a few minutes.

An eSIM installs before you board and connects the moment you land. An airport SIM requires a queue at the Digi Mobil or Orange kiosk, a passport photocopy, and sometimes a Romanian address. Pricing is similar, but the eSIM saves thirty minutes and lets you validate your STB Activ metro ticket before you leave the terminal.

Yes. Revolut needs live data to fetch exchange rates, confirm payments, and split bills. The eSIM provides that connectivity across Bucharest, Brașov, Cluj-Napoca, and other cities. Revolut is widely accepted in Romanian cafés, restaurants, and shops.

Fifty to eighty megabytes for a full day of turn-by-turn navigation in Bucharest or Brașov. Add another twenty megabytes if you search for restaurants or check transit schedules. Download offline maps for the Transfăgărășan and the Făgăraș Mountains before you drive or hike.

Yes. Constanța and the Black Sea resorts (Mamaia, Vama Veche) have reliable LTE on Orange Romania and Vodafone Romania in summer. Expect congestion on weekends in July and August. The rural Danube Delta is 3G-only on Telekom Romania.

Yes. Hotspot is enabled by default on esima eSIMs for Romania. You can share data with a travel partner or connect a laptop in a Bucharest café or a Brașov hotel. No extra charge, no throttling on the first few gigabytes.
