eSIM for Romania

eSIM, roaming or a local SIM in Romania

The right choice depends on where your SIM comes from, how long you are staying and how much you rely on your phone.

How much data to plan for

Your data use depends on what you do rather than how long you stay. These are rough figures, not guarantees:

• Maps and navigation: a few megabytes per hour. Useful on Romania's long road journeys, and offline maps reduce it further.
• Messaging and email: light, unless you send lots of photos and video.
• Social media: moderate, more with auto-playing video.
• Video calls: often several hundred megabytes per hour.
• Streaming: heavy, and the main reason plans run out early. Long train rides make it tempting.

Install your eSIM before you travel

Installing an eSIM needs an internet connection, so do it at home. First check your phone supports eSIM and is carrier-unlocked.

Then follow the install guide for iPhone, Samsung or Pixel. Label the line clearly, keep your home SIM as default for calls and texts, and set the Spidot line for mobile data.

• Install a day or two before your flight.
• Keep the QR code email somewhere you can find it.
• Download offline maps for the regions you will visit, particularly mountain areas and the Danube Delta.
• Install the apps you will need for trains, taxis and accommodation while on home Wi-Fi.

Arriving in Romania

The main international gateway is Bucharest Henri Coandă International Airport, at Otopeni north of the city. Cluj-Napoca, Timișoara, Iași and Sibiu also have international airports, which can be handy if you are heading straight for Transylvania or the west. Some travellers arrive by train or bus from Budapest, or by road from neighbouring countries.

When you land, set the Spidot line for mobile data and turn on data roaming for it, as shown in our data roaming guide. Give the phone a minute or two; if there is still no data, toggle flight mode.

Coverage in cities, mountains, the Delta and the coast

In Bucharest, Cluj-Napoca, Timișoara, Iași, Brașov, Sibiu, Constanța and other cities, mobile data generally works as you would expect. Main roads and railway lines between larger towns are usually well covered too.

Romania has a lot of mountain and wilderness, though, and that is where you should plan ahead:

• The Carpathians: the mountains that curve through the middle of the country contain some of Europe's wildest landscapes. Hiking areas such as the Bucegi, Piatra Craiului, Făgăraș and Retezat ranges have stretches with weak or no signal, particularly in deep valleys and on remote ridges.
• Mountain roads: the Transfăgărășan and Transalpina high roads are famous drives, usually open only in the warmer months. Signal can disappear on stretches between the valleys, so download offline maps and know your route.
• The Danube Delta: the Delta is a protected wetland reached by boat from Tulcea. Villages have some coverage, but out on the channels and lakes signal can be patchy. Download maps and anything else you need before you set off.
• Maramureș and Bucovina: rural areas in the north with hills, forests and small villages, where coverage can vary between settlements.
• The Black Sea coast: resorts such as Mamaia, just north of Constanța, and the towns further down the coast are generally well covered, though networks can feel slower in peak summer crowds.

Using data on trains, buses and road trips

CFR Călători, the national rail operator, runs services between most major cities, and some private operators run regional routes. Trains are a relaxing way to see the countryside, but journeys can be long. Data on board is usually good enough for messaging and browsing, with gaps in mountain passes and remote countryside.

Long-distance buses and minibuses, often called maxi-taxis, connect many towns that the railway serves less conveniently. Having data lets you check departures, find the right bus station, which is not always next to the railway station, and follow your progress.

Personal hotspot and tethering

Your phone can share its eSIM data with a laptop or tablet through personal hotspot. It uses the line selected for mobile data, so make sure that is the Spidot line. This is useful in guesthouses in rural Transylvania or Maramureș, where Wi-Fi may be slow or unreliable.

Hotspot use adds up quickly. Pause cloud backups, automatic updates and video autoplay on connected devices, and keep an eye on your remaining data. An unlimited plan makes regular tethering much simpler.

Staying safe on public Wi-Fi

Wi-Fi is widely available in Romanian hotels, cafés, restaurants and shopping centres. It is convenient, but open networks can be insecure.

• Switch to your eSIM data for banking, payments and logging in to accounts.
• Check the network name with staff before connecting.
• Turn off automatic joining of open networks.
• Keep your phone and apps updated.

Practical tips for Romania

Some local knowledge that makes a data connection even more useful:

• Currency: Romania uses the leu (RON), not the euro. Cards and contactless payments, including Apple Pay and Google Pay, are widely accepted in cities and larger businesses. Carry cash for markets, rural guesthouses and small village shops.
• Ride-hailing: Uber and Bolt both operate in Bucharest and several other large cities. Using an app is generally easier than hailing a taxi on the street, especially at the airport and main stations.
• City transport: Bucharest has a metro, trams and buses, and contactless card payments are accepted on much of the network. In other cities, check how tickets are bought before you board.
• Train tickets: CFR Călători sells tickets online and in its app, which saves queueing at the station.
• Language: Romanian is a Romance language, so speakers of Italian, Spanish or French may recognise many words. English is common among younger people in cities. A translation app with Romanian downloaded for offline use helps in rural areas.
• Mountain safety: weather in the Carpathians can change fast, and brown bears live in many forested areas. Follow local advice, stick to marked trails and do not rely on your phone as your only safety tool.

Combining Romania with nearby countries

Romania is often combined with Hungary, linked by train between Budapest and Transylvania, or with Bulgaria, across the Danube from Bucharest towards Ruse, Veliko Tarnovo and Sofia. Some travellers continue along the Black Sea coast.

For a trip through several countries, a Europe plan is usually easier than separate eSIMs. Check the countries listed on the Europe plan page to make sure your whole route is covered; if you are going to Moldova, Ukraine or Serbia, confirm whether they are included. If you are visiting Romania only, a Romania plan is the simplest option.
