Romania eSIM

Mobile Networks & Coverage in Romania

e1sim Romania plans run on DIGI — one of Romania's major mobile networks, in the country that famously ranks among Europe's fastest for internet. 4G LTE covers Bucharest, Brașov, Cluj-Napoca, Sibiu, Timișoara and Iași, the Transylvanian towns and the main Carpathian valleys, plus the Black Sea coast around Constanța and Mamaia.

Romania is big and wonderfully rural — and the headline drives prove it: the Transfăgărășan and Transalpina mountain roads have signal at the viewpoints and passes, though brief gaps occur between hairpins. In the remoter Carpathian wilderness — home to Europe's largest brown bear population — and in the Danube Delta's channels, coverage thins out; download offline maps for backcountry hikes and boat days, and enjoy being genuinely off-grid for a few hours.

Transylvania, Bucharest & the Carpathians — Castles, Dracula & Mountain Roads

Transylvania is the Romania people come for — a landscape of fortified Saxon towns, hilltop citadels and castles straight from a storybook. Bran Castle, marketed as "Dracula's Castle", clings photogenically to its rock (Vlad the Impaler's real connection is thin, but the towers and secret staircase deliver anyway); Peleș Castle at Sinaia is the genuine masterpiece — a Neo-Renaissance royal residence so lavish it was the first castle in Europe with electricity. Brașov anchors the region beneath Mount Tâmpa with its Gothic Black Church and café-lined Council Square; Sighișoara, a UNESCO-listed citadel of colourful houses and a 14th-century clock tower, is the birthplace of Vlad himself and arguably Europe's prettiest inhabited fortress. Sibiu adds Germanic squares watched by the famous "eyes" in its rooftops, and the villages of Viscri and Biertan preserve fortified churches where time stopped around 1700.

Bucharest is the counterweight — a capital of belle-époque boulevards (the "Paris of the East") colliding with communist gigantism: the Palace of the Parliament is the heaviest building on earth, 1,100 rooms of marble commissioned by Ceaușescu, and tours of its absurd interior are unmissable. The old town of Lipscani runs on cafés, and Therme București — Europe's largest urban thermal complex — handles recovery days. Beyond: the Transfăgărășan, called "the best road in the world" by Top Gear, switchbacks up to the glacial Bâlea Lake at 2,042 m (open roughly July–October); the painted monasteries of Bucovina glow with 500-year-old exterior frescoes (UNESCO); the Merry Cemetery of Săpânța in Maramureș tells villagers' life stories in witty verse on sky-blue crosses; and the Danube Delta — Europe's greatest wetland — hosts pelicans, 300 bird species and fish-fry lunches reachable only by boat.

eSIM vs Roaming in Romania

Roaming in Romania with North American, UK or Asian carriers typically costs $5–12 per day. A prepaid e1sim plan starts under €2 and works out several times cheaper per gigabyte on larger packages — and with Romania's famously fast networks, you actually get speed for your money.

Romania plans are data-only: your home number stays active for calls and banking SMS, while WhatsApp, Google Maps, Bolt and Uber, CFR train tickets and translation apps all run on local DIGI data. Romania uses the leu (RON), not the euro, so a currency-converter app on local data comes in handy. The QR code arrives by email within minutes of purchase — you're online before you leave Otopeni airport.
