If you're packing your bags, you're probably wondering about internet in Romania and which option suits you best to stay connected without bill shocks. I'll tell you clearly and without fluff: I compare all real alternatives—your own plan, accommodation Wi-Fi, a Romanian SIM, and an eSIM—with coverage data and prices, so you can choose wisely and not based on marketing.
How to get connected in Romania
In Romania, you can connect in four ways: roaming with your Spanish plan (free within the EU if your plan includes it), accommodation Wi-Fi—among the fastest in Europe—a local prepaid SIM, or an eSIM. For most travelers, roaming is enough; an eSIM is only worth it in specific cases.
The good news is that Romania is a surprisingly well-connected country. Its fiber optic network is among the best on the continent, and for mobile telephony, 4G covers almost the entire territory, with 5G already deployed in major cities. You're not going to a destination where it's hard to find a signal: you're going to one where, in general, you'll have better internet than in many parts of Spain.
That changes the question. It's not so much "will I have coverage?" as "what's the cheapest and most convenient way to use it?" And that's where four different paths come in, which you should know before spending an extra euro. In the following sections, I break down each one honestly: what it costs, who it makes sense for, and where the fine print is that almost no one tells you. My goal isn't to sell you the most expensive option, but to help you get it right the first time.
Your Spanish plan: almost always included
Let's start with the most important thing and what is least often said: Romania is part of the European Union, so your Spanish mobile plan works there under the Roam Like At Home rule. This means you can browse, call, and send messages using your usual allowance at no extra cost, just as if you were in Madrid or Seville.
There's a key nuance: the fair use policy. Operators don't give you unlimited data outside your home country, but a cap calculated with a European formula that depends on the price of your plan. The rule is, at a minimum, twice the result of dividing your plan's price (without VAT) by the wholesale price per gigabyte, which in 2025 is around €1.30/GB and will decrease to €1/GB by 2027. In practice, a plan costing €20-30 per month usually gives you around 30-40 GB to spend in the EU: more than enough for a normal trip.
Be careful with two cases: "unlimited" data plans that are very cheap often have a small roaming data cap, and the system is designed for temporary trips, not for living abroad (it's checked over four-month windows). If you have doubts about your specific allowance, comparing eSIM vs. traditional roaming might help.
My honest advice: if your Spanish plan is recent and includes the EU, don't complicate things. Save the paid alternative for when you truly need it.
When an eSIM is truly worth it
Just because roaming is free doesn't mean it's always the best idea. There are a few very clear scenarios where an eSIM saves you money or trouble, and I want you to consider them without exaggeration.
The first, and most important: travelers from outside the EU. If you're traveling from the UK, Latin America, the United States, or any country outside the European area, your plan won't have Roam Like At Home, and classic roaming can cost a fortune. In this case, a local eSIM is almost mandatory.
The second: old or low-cost plans with tiny caps. Some old plans don't include the EU, or only give you 2-3 GB of roaming. If you consume a lot of data (maps, video, remote work), you'll run out quickly.
The third: those who want to separate lines. Keeping your Spanish number for calls and bank two-factor authentication, and browsing on a separate data line, is convenient and prevents you from using up your allowance. If you've never used this technology, it will be helpful to read what an eSIM is and how it works. And if you're torn between it and traditional plastic, here I compare eSIM and local SIM in detail.
Hotel Wi-Fi and public Wi-Fi
Romania boasts, rightly so, one of the fastest fixed internet connections in Europe. Its fiber infrastructure is among the fastest on the continent, and this is noticeable in everyday life: Wi-Fi in hotels, apartments, cafes, and restaurants usually works very well, often with speeds that exceed what you have at home.
For a traveler, this is gold. If your accommodation has good fiber, you can do almost all heavy data consumption there: upload photos and videos, long video calls, download offline maps from Google Maps or Maps.me, plan routes, and watch series at night. This way, you head out with your mobile data allowance almost intact.
That said, don't rely solely on Wi-Fi. In cafes and public spaces, the connection is open, so avoid sensitive operations (banking, passwords) or use a VPN if you do them. And remember that Wi-Fi doesn't accompany you on the bus, at Bran Castle, or on a hike in the Carpathians: to navigate with a map in hand, you definitely need mobile data. The winning strategy is usually to combine both. If you're considering a portable router, you might be interested in comparing eSIM vs. pocket Wi-Fi.
Local SIM: Orange, Vodafone, Digi, and Telekom
The classic option for long-term travelers is to buy a Romanian prepaid SIM card. The main operators are Orange, Vodafone, and Digi; Telekom, which operated for years, has been integrating with others, so in practice today you primarily choose between these three. You can buy one as soon as you land, at the airport itself, and also in official stores, shopping malls, supermarkets, and kiosks.
Prices are very competitive. The physical card usually costs between 10 and 20 RON (about 2-4 €), and data bundles start very cheaply. Here's an estimate of starting prices for 30 days:
| Operator | From (30 days) | Approx. data | Note |
|---|---|---|---|
| Digi | ~3-4 € | 10-15 GB | The most economical |
| Orange | ~5 € | 10-15 GB | Strong in urban 5G |
| Vodafone | ~6 € | ~12 GB | Good urban coverage |
| Telekom | — | — | Integrating with others |
The downside: you have to remove your SIM, physically change it, perhaps show your passport to register it, and lose your Spanish number while it's in use. For long stays or heavy consumption, it's very cost-effective per gigabyte; for a weekend, it's usually more hassle than benefit. And don't forget to store your original card safely so you don't lose it during your trip.
Coverage in Bucharest, Transylvania, and the Carpathians
Let's look at the real map, because the theory of "there's coverage" falls short. In Bucharest, the connection is excellent: 4G and 5G throughout the center, the Old Town (Centrul Vechi), metro lines, and main avenues. In Calea Victoriei and central areas, it's easy to see 150-300 Mbps on 5G. The capital was, in fact, the first city in the country with full 5G coverage on a network.
In Transylvania, you're also well-covered. Tourist cities and towns like Brașov, Sibiu, Cluj-Napoca, or Sinaia have very good 4G, and several already have 5G. At Bran Castle and in rural Transylvania, it's normal to get 4G at 30-80 Mbps: more than enough for maps, messaging, and finding a place to eat.
Things get a bit trickier in the Carpathians. On iconic mountain roads—Transfăgărășan, Transalpina—there's signal on most stretches, but in narrower valleys, forested gorges, and uninhabited areas, you might lose it; this happens with any operator. My trick: before setting out, download an offline map of the area. That way, even if you lose data for a while, you'll still know where you're going.
How much data will you need
People almost always overbuy here. An average traveler consumes less than you think, especially if they use hotel Wi-Fi for heavy tasks. To give you a realistic idea, here's how much each use consumes:
| Usage | Approximate consumption |
|---|---|
| Maps and GPS | ~5-10 MB per hour |
| WhatsApp and web browsing | ~200-500 MB per day |
| Social media with video | ~1 GB per hour |
| HD video streaming | ~1-1.5 GB per hour |
Translated to a trip: if you use your phone for navigation, messaging, some searching, and moderate social media, you'll use about 500 MB to 1 GB per day. A one-week getaway will be well covered with 3-7 GB. If you watch a lot of videos on the street or work remotely, raise the estimate to 1-2 GB daily.
That's why I insist on something: you don't need a giant data plan. Your European roaming or a modest plan will suffice, and you avoid paying for gigabytes you won't use. Downloading maps and playlists from your accommodation's Wi-Fi almost halves mobile consumption. Adjust your purchase to your real usage, not that of an influencer who records stories every ten minutes.
Comparison: which option to choose
With all the above on the table, the choice becomes much simpler. There isn't one single answer: there's a best option depending on your type of trip. This table summarizes the four alternatives for a quick glance:
| Option | Ideal for | Advantage | Disadvantage |
|---|---|---|---|
| Your plan (EU) | Modern plan, short trip | Free and with your number | GB cap according to plan |
| Hotel Wi-Fi | Heavy usage at accommodation | Very fast and free | Only where there's network |
| Local SIM | Long stays, lots of data | Low price per GB | Change card and number |
| eSIM | Outside the EU or plan without roaming | Activate before flying | Requires compatible phone |
My practical summary: if you're Spanish with a recent plan and going for a few days, use your own allowance, full stop. If you're coming from outside the EU, your plan is old, or you'll consume a lot, an eSIM gives you peace of mind and you can activate it from home. And if you're staying for weeks, consider a local SIM for the price. For the specific case of this destination, with updated prices and installation tips, you have all the fine print in my eSIM guide for Romania.
How to activate step-by-step
Whatever your choice, getting your phone ready takes barely five minutes. Here's the routine I follow to avoid surprises when landing at Henri Coandă Airport in Bucharest.
- If you use your Spanish plan: confirm with your operator that the EU is included and how many GB of roaming you get. Activate data roaming in your phone settings before you leave.
- If you choose an eSIM: buy it and install it in Spain using Wi-Fi. Scan a QR code, set it as your secondary data line, and leave it ready to connect automatically upon landing.
- If you prefer a local SIM: bring your passport, buy it at an official airport counter, and ask them to activate and configure it right there.
A couple of settings that save data and battery: activate system data saver, disable automatic app updates except via Wi-Fi, and download your offline maps the night before. If you're concerned about how much you might pay for exceeding your classic roaming, take a look at how much international roaming costs before deciding. With these steps, you'll land connected and without unexpected expenses.
Frequently asked questions
Is internet in Romania free with my Spanish plan?
Yes, if your plan includes the EU. Romania is in the European Union, so you can browse with your usual allowance without surcharge, within the fair use limit set by your operator.
Do I need an eSIM if I'm only going for a few days?
Normally not, if you're Spanish with a modern plan: your European roaming is sufficient. An eSIM makes sense if you're coming from outside the EU, your plan is old, or you're going to use a lot of data.
How many GB do I need for a week in Romania?
For normal use (maps, messaging, some social media), 3-7 GB is plenty. If you use hotel Wi-Fi for heavy tasks, even less. Only increase the estimate if you watch a lot of videos on the go.
Is there good coverage at Bran Castle and in the Carpathians?
At Bran and in rural Transylvania, you'll have decent 4G (30-80 Mbps). In the mountain passes of the Carpathians, there's signal on almost all stretches, but in narrow valleys, you might lose it occasionally.
Does hotel Wi-Fi work well in Romania?
Very well. Romania has one of the best fiber networks in Europe, so Wi-Fi in accommodations and cafes is usually fast and stable. Ideal for heavy consumption.
Can I buy a Romanian SIM at the airport?
Yes. In the arrivals area of Bucharest airport, there are operator counters. Bring your passport in case they ask for it when registering, and ask them to configure it for you there.
What if I'm traveling from outside the European Union?
You won't have Roam Like At Home, so classic roaming can be very expensive. In that case, a local eSIM or a Romanian SIM is almost always the most sensible and cheapest option.
Conclusion
Getting connected in Romania is easier and cheaper than it seems. If you're Spanish with a recent plan, your own allowance is sufficient for most things, supplemented by the excellent Wi-Fi in accommodations. A local SIM shines for long stays, and an eSIM is a lifesaver for those traveling from outside the EU or with a plan without European roaming.
Whatever you choose, the key is to sort it out before leaving home: no last-minute scrambling with your luggage in hand and time running out. If your situation calls for an eSIM, you can get it ready in minutes with PuraSIM's eSIM for Romania and land in Bucharest already connected. Have a great trip, and may the only surprise be how beautiful Transylvania is.
