The 60-second verdict
Romania is excellent value for travel data and we are far cheaper than the alternatives: Airalo's cheapest 30-day Romania plan is $69.00 and Holafly's is $76.50, because both sell the country as unlimited-only. Nomad is the only other provider offering fixed data here, at $12.50 for 5 GB / 30 days; we came in below that in October 2026.
Romania also has genuinely fast mobile internet. It consistently ranks among Europe's better countries for fixed and mobile speed, so the 5G you get in Bucharest is not a downgrade on home.

Romania's networks
Orange, Vodafone and Digi are the three that matter. Orange and Vodafone have the broadest rural coverage and are the ones travel eSIMs typically use; Digi is the budget domestic favourite and strong in cities. Coverage across Romania is good, including in most of Transylvania — the gaps are mountain passes and forest, not towns.
Winter in Romania: markets and mountains
Romania has become a serious winter destination, and the two draws have different connectivity profiles. The Christmas markets — Bucharest, Sibiu, Brașov, Craiova, Cluj — are all city-centre and have excellent 5G, so nothing to plan around. The mountains are the other story.
- Poiana Brașov and Sinaia — good coverage in the resorts and on the main lifts.
- The Transfăgărășan — spectacular, and closed roughly November to June. Do not plan a winter drive over it. When it is open, expect real coverage gaps at altitude.
- Bucegi and Făgăraș hiking — patchy above the treeline. Download offline maps.
- Bran and Peleș castles — both fine, both busy.
Coverage by destination
- Bucharest — excellent 5G, including the metro and Otopeni airport.
- Brașov, Sibiu, Cluj-Napoca, Timișoara — strong throughout the old towns.
- Painted monasteries of Bucovina — usable in the villages, thinner between them.
- Danube Delta — genuinely patchy. Boat trips into the channels will lose signal.
- Maramureș — fine in the main villages, weak on the back roads.
How much data do you need?
A week in Bucharest and Transylvania runs 2–4 GB for most travellers, and Wi-Fi is widely available and fast in Romanian cafés and hotels. Buy 5 GB at $6.75 unless you are working remotely, in which case 20 GB at $20.50 is still cheap.
Setting it up
- Buy and install on Wi-Fi before you fly.
- Switch the line on at Otopeni and enable Data Roaming for that line only.
- Turn Data Roaming off on your home line.
- Download offline maps for Transylvania if you are driving — mountain sections do drop out.
- Remember Romania uses the leu, not the euro, despite being in the EU.
Frequently asked questions
What is the best eSIM for Romania?
Flysimio is the value pick on Vodafone and Orange — we came in below Nomad's $12.50 for 5 GB / 30 days in October 2026, against $69.00 for Airalo's cheapest 30-day Romania plan, which is unlimited-only. Romania also has fast mobile internet, so the cheaper plan is not a slower one.
Is mobile coverage good in Transylvania?
Yes in the towns — Brașov, Sibiu, Cluj and Sighișoara all have strong signal. Coverage thins on mountain roads, above the treeline in the Făgăraș and Bucegi ranges, and in the Danube Delta channels.
Can I drive the Transfăgărășan in winter?
No. The Transfăgărășan is closed roughly from November to June because of snow at altitude. Plan winter itineraries around Brașov, Sibiu and the ski resorts instead, and expect coverage gaps at altitude even when the road is open.
How much data do I need for Romania?
About 2–4 GB for a week covering Bucharest and Transylvania. Wi-Fi is fast and widespread in Romanian hotels and cafés, so a 5 GB plan at $5.95 is comfortable for most trips.
Does Romania use the euro?
No. Romania is in the EU but still uses the Romanian leu (RON). This catches out travellers who assume euro pricing, and it is worth having a card that does not charge foreign transaction fees.
