Best eSIM for Romania 2026: 15 Providers Compared

Mobile data in Romania is fast and inexpensive: Orange, Vodafone and Digi run dense 4G and widespread 5G in Bucharest, Cluj, Brasov and Timisoara, and only the deep Carpathian back-country loses signal. Romania offers medieval Transylvania, the castles of Bran and Peles, the buzz of Bucharest and the wild Carpathian mountains. Getting around runs on good data for maps, transit and messaging, and an eSIM is the cleanest way to get it: install before you fly, land at Bucharest, and your phone connects to a fast network the moment you switch it on. This guide compares the best eSIM options for Romania, explains what Orange, Vodafone and Digi deliver, and helps you pick the right plan.

Orange, Vodafone and Digi: Romania's networks in the 2025 nPerf barometer

The nPerf 2025 barometer for Romania, covering January to December 2025, puts Orange clearly ahead with 89,242 nPoints and a download speed of 116.87 Mbps. Vodafone is second at 54.85 Mbps, Digi third at 54.28 Mbps with the second-best upload speed, and Telekom fourth. That last network no longer exists as a separate brand: in October 2025, Telekom Romania's mobile customers moved to Vodafone, and its prepaid business to Digi.

All three remaining operators run 4G across the country and 5G in Bucharest, Cluj-Napoca, Timisoara, Brasov and Iasi. For a visitor, the difference shows mostly in the mountains, where one network may reach a valley another does not. Each Simsima plan for Romania names its network in the plan details.

EU travelers in Romania: Roam Like at Home, and Moldova too

Romania is in the EU, so SIMs from other EU countries, Iceland, Liechtenstein and Norway work there at home prices under the EU's Roam Like at Home rules, within your operator's fair-use limit. The same EU page lists Moldova and Ukraine as covered by the regime, which matters if your trip continues from Iasi to Chisinau.

A travel eSIM is mainly for visitors from the UK, the US and other countries outside that zone, and for EU travelers whose fair-use allowance is small. If you head south into Serbia, remember that EU roaming does not apply there.

Transfagarasan, Bucegi and the Danube Delta: coverage outside the cities

Bucharest, Cluj, Timisoara, Sibiu, Brasov and the medieval towns of Sighisoara and Viscri are well covered, as are the A1 motorway and the main rail lines. The Transfagarasan road, open only in summer, has signal near Balea Lac and the Vidraru dam and gaps on the high bends between. In the Bucegi and Retezat mountains, ridges often have signal and deep valleys do not.

The Danube Delta is the main weak spot: Tulcea is covered, but on boat trips through the channels toward Sulina or Sfantu Gheorghe, expect slow or no data in places. Maramures villages and Bucovina's painted monasteries have 4G near the main roads. Download offline maps before hiking or heading into the delta.

Bucharest, Brasov, Sibiu and Cluj in ten days

A typical first trip spends three days in Bucharest, takes the train to Brasov for Bran and Peles castles, continues to Sighisoara and Sibiu, and ends in Cluj-Napoca. You can buy train tickets on CFR Calatori's website, the state rail operator, and keep them on your phone. Bolt and Uber work in Bucharest and the larger cities, and data also goes on Google Maps, restaurant bookings and translating Romanian signs.

Allow 400 to 700 MB a day, around 4 to 7 GB for ten days. A mid-size capped plan from the tables covers it; remote workers in Bucharest or Cluj, both popular with long-stay visitors, are better off with an unlimited plan.

What an eSIM won't do for you in Romania

• No Romanian number: parking by SMS in some cities and a few delivery apps expect a local line
• Sharing data with a laptop or a second phone in Bucharest depends on the plan's hotspot terms
• Unlock your phone and check eSIM support before flying to Bucharest or Cluj
• Remote valleys in the Carpathians and parts of the Danube Delta have weak coverage on any network

For a longer route through Hungary, Bulgaria or the Balkans, a regional Europe plan can replace several country plans; the guide below explains which countries each zone covers.

Best eSIM plans for Romania

Mobile data is inexpensive in Romania by European standards: in the ITU's 2025 ICT price baskets, 5 GB of data-only mobile broadband cost about US$6.26, against a median of about US$10.51 across Europe, so eSIM prices tend to be low and allowances go a long way. Simsima runs on the local networks with transparent pricing. Here is how a light 1 GB pack compares across eSIM providers:

If you would rather not track your usage, Romania also has unlimited-data eSIMs, with speed reduced after a daily high-speed allowance until the next day. Here is how the unlimited plans compare:

Simsima's full Romania lineup runs from small packs up to larger monthly allowances on the fast local networks. Because data is so cheap here, a 3 to 5 GB plan comfortably covers most trips, and heavier users pay little to size up. Many Romania eSIMs also work across the wider EU if your trip continues.

How to install your Romania eSIM

Installation takes a couple of minutes and is best done at home on Wi-Fi before you fly. The plan activates on its own when it connects to a local network on arrival, so the validity window does not start early.

1. Buy your Romania plan on Simsima and open the confirmation with your QR code
2. On your phone, go to Settings, then Mobile or Cellular Data, and choose Add eSIM
3. Scan the QR code or use the one-tap install link, then label the plan Romania
4. Keep your home line as default for calls and texts, and set the eSIM for data
5. Turn on data roaming for the eSIM line only, then land in Bucharest and go online
