eSIM for Romania

Romania stretches from Bucharest's Belle Epoque boulevards to the painted monasteries of Bucovina, with Brasov, Sibiu, and the Transylvanian castles in between. You'll want data to book a Bran Castle day tour, message your Airbnb host in Cluj-Napoca, and run real-time translation at village markets in Maramures. Bolt and Uber both work in the bigger cities, and offline maps help when you're winding the Transfagarasan or hunting brown bears in the Carpathians.

How to install your Romania eSIM in 3 steps

Setting up a Romania eSIM takes about as long as reading this paragraph, and doing it before you leave means Orange, Vodafone, or Digi is already talking to your phone the moment the wheels touch down at Henri Coandă International.

1. Pick a data tier against the table further down and check it against £0.64 - the QR code lands in your inbox within minutes, so there is nothing to queue for at an arrivals kiosk.
2. While you are still on home Wi-Fi, install the profile: iPhone users go to Settings > Cellular > Add eSIM and scan the code; Android users go to Settings > Network & Internet > SIM Manager > Add eSIM. Do this before boarding - airport Wi-Fi at Henri Coandă is fine for browsing but not always reliable for a fresh install.
3. Once you land, switch on data roaming for the new eSIM line and leave your home SIM as the default for calls and texts. Orange, Vodafone, and Digi all pick up the new profile automatically, so there is no fumbling for a signal bar on the drive into central Bucharest.

Mobile network coverage in Romania

Bucharest, Cluj-Napoca, and Timișoara

All three operators cover Romania's major cities well, but they are not interchangeable. Orange has rolled out 5G to the widest number of towns and cities and is the safer pick if consistent coverage matters more than peak speed. Vodafone's 5G footprint is smaller, but where it is live its median speeds tend to run ahead of the competition. Digi is the value operator and is still building out its 5G network year over year, though its 4G already reaches the same population as the other two. Expect strong 4G everywhere in Bucharest, Cluj-Napoca, and Timișoara regardless of which network your eSIM rides on.

The coast, the Danube Delta, and the Carpathians

Black Sea resorts around Constanța hold a steady 4G signal, as do Danube Delta settlements, even though the marshland in between can be patchier. Inland, mountain towns that see the most tourist traffic - Bran, Sinaia, Brașov - keep usable 4G, and villages in Maramureș and Bucovina are generally connected too. The catch is altitude: deep Carpathian valleys and the more isolated high trails can lose signal entirely, so anyone hiking seriously in the mountains is better off with an eSIM plan that can fail over between networks rather than relying on a single carrier.

Roads, rail, and crossing the country

Romania's motorways and main national roads carry a dependable 4G signal from all three operators, which makes an eSIM a practical option for a road trip between cities. Rail is a little less consistent: trains climbing through Carpathian passes can drop signal for short stretches between tunnels and ridgelines, so do not count on a video call holding steady the whole way from Brașov to Sighișoara. Overall population coverage for 4G sits in the high nineties percentage-wise, so gaps are the exception rather than the rule.

How much data do you need for your trip to Romania?

Usage style	Daily estimate	1-week trip	Good fit
Light - maps, messaging, occasional browsing	~300 MB	2–3 GB	See light-use plans
Moderate - social media, music, some video	~750 MB	~5 GB	See moderate-use plans
Heavy - streaming, hotspot, video calls	1.5 GB+	10–20 GB	See heavy-use plans

eSIM vs. roaming vs. a local SIM in Romania

	Travel eSIM	Home-carrier roaming	Local SIM
Typical cost	Plans from £0.64	Often £9+ per day on a flat-rate pass	Around £11, plus the hassle of finding a shop
Setup	Install the QR code before you fly; live the moment you land	Toggle roaming on your existing SIM - nothing to install	Find an Orange, Vodafone, or Digi counter after arrival and swap the physical card
Keep your number	Yes - runs alongside your home line as a second profile	Yes - it is your existing number	No - you are issued a new Romanian number
ID/passport needed	No registration required to activate	None - it is your existing account	Romania does not mandate tourist SIM registration, one of the few EU countries that does not, though some retail counters still ask to see a passport at the till

Anyone signing a Romanian lease, taking a local job, or opening a bank account will eventually want a proper Digi or Orange contract SIM rather than a travel eSIM, since a local number unlocks things like courier deliveries and local banking apps - that switch makes more sense once you have settled in than before you have even booked the flight.

Tips for staying connected in Romania

• Dial 112 for police, fire, or ambulance - it is free from any phone, even one without an active SIM, and call-takers handle English alongside Romanian.
• Heading into the Carpathians for a multi-day hike? Download offline maps first, since deep valleys and the more remote high-altitude trails can lose signal even where nearby towns stay connected.
• Romania does not require tourist SIM registration, so a physical top-up at a Digi or Orange kiosk is quick if you ever need a backup line alongside your eSIM.
• If you are chasing raw speed over guaranteed coverage, Vodafone tends to post the quickest results where its 5G is live; if you would rather have the wider net, Orange currently reaches more cities.
• Crossing by train between cities through the mountains, expect a few short gaps in a video call rather than a dropped connection for the whole journey.
• Planning a wider Balkan loop from Bucharest? Check the Europe eSIM options for coverage that spans multiple countries on one plan.

Traveling beyond Romania?

Romania sits at the crossroads of the Balkans and Central Europe, so many trips extend past the border. If your route continues onward, take a look at eSIM for Bulgaria heading south, eSIM for Hungary to the west, eSIM for Moldova just across the Prut, or eSIM for Serbia if you are looping through the western Balkans. Further afield, eSIM for Turkey and eSIM for Greece are both popular add-ons for travelers combining Romania with a Black Sea or Aegean leg.
