Bucharest is an easy city to be online in and a slightly awkward one to buy connectivity for, because the local prices are so low that they warp the comparison. A Romanian prepaid top-up costing about 26 lei will hand you 250 GB, which no travel eSIM will ever match, and yet most short-stay visitors are still better served by an eSIM that connects the moment they land at Henri Coanda and behaves the same way if the trip continues to Sofia or Budapest. The networks themselves are not the problem: Orange, Vodafone and Digi all blanket the city, all five metro lines carry signal through the running tunnels rather than only on the platforms, and free WiFi is close to a civic reflex in Romanian cafes. What you are really choosing between is volume and portability.

Bucharest Mobile Coverage
Three operators cover Bucharest and none of them will let you down inside the city. Orange Romania holds the country's strongest low-band spectrum position and won the most recent national coverage assessment with 7.3 points out of 10, alongside roughly 57 percent 5G availability. Vodafone Romania is the speed leader after absorbing Telekom Romania Mobile's spectrum in the 2025 breakup, posting median 5G downloads near 180 Mbit/s in early 2026, roughly double its own figure a year earlier. Digi, the RCS and RDS mobile arm, leads the country on 4G availability at close to 98 percent and records the lowest latency and fastest page loads of the three, which is the difference you actually feel when a map tile or a card payment has to load.
The city is dense enough that all six sectors get comfortable 4G and widespread 5G, with the strongest build-out through Sector 1 in the north, along Calea Victoriei and Bulevardul Magheru, and around the Piata Victoriei and Aviatorilor business spine. Where Bucharest occasionally disappoints is not the network but the buildings: the thick interwar masonry of Cotroceni and Armeneasca, and the concrete slab blocks that fill Berceni and Drumul Taberei, both eat signal several floors in. If your apartment sits in the back of a 1930s villa, expect to lean on the WiFi.
Nationally, 5G is thinner than Bucharest suggests
Do not extrapolate from the capital. Romania's overall 5G availability sat near 39 percent in early 2026, among the lowest figures in Central and Eastern Europe, and the cause is spectrum policy: the 2022 auction released only 30 MHz of the 700 MHz band nationally, roughly half what neighbouring markets assigned. That starves the low-frequency layer that would otherwise push 5G across the countryside. In Bucharest you will barely notice. On the drive to Brasov you will, and the difference is why the operator your plan rides matters more outside the city than in it.
Metro Tunnels, Trams and What a Ticket Costs
The Bucharest metro runs five lines and 63 stations across roughly 77 kilometres, and the tunnels are wired for mobile data, not merely the platforms. The national regulator ANCOM has measured this directly, walking the network with mobile equipment across both directions of every line and mapping around 9,600 measurement points. Cumulative coverage across operators came out at 99 percent, with tunnel coverage of 90 percent for RCS and RDS, 88 percent for Orange and 87 percent for Vodafone. The one weak column in that survey belonged to Telekom Mobile at 66 percent, and since those masts were split between Digi and Vodafone in the 2025 sale, the laggard has effectively been absorbed.
In practice that means you can keep navigating between Piata Unirii and Piata Victoriei without surfacing, and the deep interchange at Unirii, where M1, M2 and M3 all meet, is one of the better-served points on the system. Above ground, the STB tram and trolleybus fleet is comfortably covered, including the long tram 41 run out to Ghencea and the 1 and 10 loops.
Two ticketing systems, two sets of prices
Metrorex, which runs the metro, and STB, which runs the buses, trams and trolleybuses, sell separate tickets and one does not cover the other. Fares were adjusted upward in May 2026: a single metro journey now runs around 7 lei against the 5 lei it had been, and a 24-hour metro pass around 18 lei. STB surface travel stayed cheaper, at roughly 3 lei for a 90-minute single. The painless method is to tap a contactless bank card straight on the metro turnstile or the validator on board a tram, which works without buying anything in advance. The 24Pay app is the local alternative if you would rather keep a record, and there is still an SMS ticketing option for the surface network. Check the machine when you arrive, because Romanian transit fares have moved more than once in the past two years.
One thing Bucharest does not yet have is a metro to the airport. Line M6 is under construction toward Otopeni, with tunnel boring already underway from Baneasa, but the first section is not expected before 2027 and the airport stretch not before 2028. Until then the airport run is a bus or a train, which the Bucharest Airport guide covers in detail.
Neighborhood Notes: Lipscani, Dorobanti, Cotroceni
Coverage in Bucharest is good enough that you will not find a genuine dead zone above ground, but the districts feel different once you are actually using a phone in them.
Old Town and Lipscani
The pedestrianised grid around Strada Lipscani, Stavropoleos Monastery and the ruins of the Old Princely Court is the densest concentration of bars and terraces in Romania, and on a Friday night the cell sites above it are working hard. Data holds up on the street, but a great many of the venues here are in vaulted brick cellars where the signal simply does not follow you down the stairs. Every one of them offers WiFi, and asking for the password is a normal part of sitting down.
Dorobanti and Floreasca
North of Piata Romana, this is the embassy and restaurant belt, a mix of pre-war villas and newer glass towers that shades into Floreasca and then into the parkland around Herastrau and Primaverii. It is where most of the city's foreign residents cluster, and unsurprisingly it has the best 5G density in Bucharest. If you are working remotely for a fortnight, this is the part of town where a tethered laptop simply works.
Cotroceni
Quiet, leafy and low-rise, ten minutes west of the Palace of the Parliament and wrapped around the Botanical Garden and the presidential palace. Outdoor coverage is fine on all three networks, but there is less 5G here than in the north, and the heavy masonry of the old villas means indoor signal drops off noticeably at the back of a ground-floor flat. Charming to stay in, worth having the WiFi password for.
The short version: pick your district for atmosphere rather than signal. The only reliable way to lose data in central Bucharest is to go underground into a cellar bar, and the fix for that is the WiFi that every one of them already offers.
Free WiFi in Bucharest
Bucharest has no single branded municipal hotspot network of the kind Vienna or Tallinn run, and looking for one will only waste your time. What it has instead is something arguably more useful: a culture in which essentially every cafe, restaurant, bar, bakery and guesthouse gives away a fast connection without being asked twice, on fibre that is among the cheapest and quickest in Europe. Romania's domestic broadband is genuinely excellent, and the venue WiFi you get in a Bucharest cafe frequently outruns the mobile data you paid for.
Reliable places to get online without a plan:
- Third-wave cafes and bakeries: the specialty coffee scene around Piata Amzei, Dorobanti and the Old Town all run open networks, usually with the password printed on the receipt or chalked on a board.
- Shopping centres: AFI Cotroceni, Baneasa, Promenada, Mega Mall and Unirea all provide free connections across the whole building.
- Hotels and guesthouses: near-universal and usually uncapped, including at the budget end.
- Long-distance trains: several intercity services on the Brasov and Constanta routes carry onboard WiFi, though it thins out badly in the Prahova Valley tunnels.
Where free WiFi stops being enough
The gap is movement. Sitting still in a cafe you need nothing else; walking between the Palace of the Parliament and the Old Town, working out which tram goes to Cismigiu, or trying to reach a Bolt driver who has stopped on the wrong side of a boulevard, you need data in your hand. Bucharest traffic also makes on-the-move navigation more valuable here than in a compact European old town, because route choice genuinely changes your evening. Treat cafe WiFi as the thing that stretches a small data plan a long way, not as a substitute for one.
Getting Online When You Arrive
Almost every visitor lands at Henri Coanda in Otopeni, about 17 kilometres north of the centre, and the first thirty minutes there set the tone for the trip.
Decide before you fly which side of the trade you are on
If Bucharest is a long stay and you are not leaving Romania, a local card bought in a mall store the following morning is unbeatable value and the eSIM is only bridging your first day. If you are here for a long weekend or continuing across a border, buy the eSIM and never think about it again. Working this out at home takes two minutes and saves an argument with yourself in arrivals.
Check the line is live before you leave the terminal
Open a map and load a route to your accommodation while you are still standing in the arrivals hall. If something has gone wrong, the airport WiFi and a staffed kiosk are both within fifty metres, which is not true once you are on a bus.
Sort the fare for the ride in
The 100 Express bus into the centre costs about 3 lei and takes 40 to 60 minutes to Piata Unirii via Piata Romana and the university, and you can tap a contactless card on board rather than hunting for a ticket machine. The rail shuttle to Gara de Nord is quicker at around 25 minutes. Bolt is the default ride-hailing app in Romania and works far better than flagging a taxi at the kerb.
Save the offline map for any mountain days
Do this on hotel WiFi on your first evening rather than in a car park in Curtea de Arges. The Bucharest area needs nothing, but the Fagaras crossing and the back roads of Transylvania will thank you.
If you want the terminal-by-terminal detail, including where the kiosks sit and what the airport network is called, that is in our Henri Coanda guide. For the full provider comparison, the Romania eSIM guide lays out which plan rides which network, and the eSIM Finder will size one against your dates.
Day-Trip Coverage: Sinaia, Bran and Brasov
Bucharest sits on the doorstep of the Prahova Valley, and almost everyone who stays more than three days heads north up the DN1 toward the mountains. This is where the choice of network stops being academic.
| Trip | Getting there | Coverage |
|---|---|---|
| Sinaia and Peles Castle | About 120 km, roughly 1h40 on the train from Gara de Nord | Good. The town and the castle approach are covered on all three networks; the forest path above Peles is patchier. |
| Brasov | 166 km by rail, 2h16 on the fastest services, around 59 lei in second class with roughly 30 departures a day | Excellent in the old town and around Piata Sfatului, with 5G in the centre. |
| Bran Castle | About 30 km beyond Brasov by bus or car | Good. Bran sits in a populated valley and all three operators reach it, so ticket queues and taxi calls work fine. |
| Transfagarasan and Balea Lac | A full day by car, open only in summer | Patchy to none. Usable near the Vidraru dam and Balea Cascada, repeatedly absent on the hairpins, frequently dead at 2,034 m. |
Two practical notes. If you drive rather than take the train, the DN1 through Comarnic and Predeal narrows to two lanes and jams hard on Friday evenings and Sunday afternoons, so a phone that can reroute you is worth more here than anywhere else in Romania. And if the Transfagarasan is on your list, plan the day as though you will be offline for large parts of it: download the route in Sibiu or Brasov, agree a meeting point with anyone you are travelling with, and do not rely on being able to call a guesthouse from the pass. An Orange-based plan is the one that gives you the most signal on that road, which is the main reason it takes the top slot in our Romania eSIM comparison.
Frequently Asked Questions
Can I keep using data while the metro is moving through a tunnel?
Yes. The regulator ANCOM measured the whole Bucharest network directly, in both directions on every line and across roughly 9,600 points, and found 99 percent cumulative coverage with individual tunnel figures of 90 percent for RCS and RDS, 88 percent for Orange and 87 percent for Vodafone. So maps, messages and music keep running between stations rather than only on the platforms. The deep interchange at Piata Unirii, where three lines converge, is among the better-covered spots on the system.
What does a metro or tram ride cost in Bucharest now?
Fares moved upward in May 2026. A single metro journey is now around 7 lei, up from 5, and a 24-hour metro pass runs about 18 lei. STB surface transport stayed cheaper at roughly 3 lei for a 90-minute single on buses, trams and trolleybuses. The two systems sell separate tickets and neither covers the other. The simplest approach is to tap a contactless bank card at the metro turnstile or on the tram validator, which needs no app and no ticket machine.
Is it worth buying a Romanian SIM instead of an eSIM for a week in Bucharest?
For a week, probably not, even though the prices are astonishing. An Orange top-up of about 26 lei loads 250 GB, but you will use perhaps 4 GB in a week, so the saving is real but modest against the hassle of a store visit on a short trip. The calculation flips hard at two weeks or more, or if you are working from a rented flat and tethering a laptop. It also flips the other way entirely if you plan to cross into Bulgaria or Serbia, because the cheap Romanian bundles carry almost no roaming data.
Are the cellar bars in the Old Town a problem for signal?
They can be. The restored buildings around Lipscani and Strada Franceza hide a lot of vaulted brick basements, and mobile signal does not reliably follow you down into them. Street level is fine on every network, even on a busy Friday. The workaround is the one locals use without thinking about it: every venue has WiFi and will give you the password with your first drink, so agree a meeting point above ground if you are trying to find friends in the district.
Will I still have data on a trip up to Sinaia, Brasov or the Transfagarasan?
Sinaia and Brasov are comfortable on any network, with 5G in the Brasov centre and solid coverage along the rail line and the DN1. Bran is fine too. The Transfagarasan is a different proposition: expect usable data near the Vidraru dam and around Balea Cascada, repeated dropouts on the switchbacks, and frequently nothing at all at Balea Lac at 2,034 metres. Download the route offline before you set off, and choose an Orange-based plan if the mountains are a real part of your itinerary.
