Internet in Ukraine: How to Stay Connected in a Country at War

If you're looking for internet in Ukraine, you're almost certainly not planning a vacation. The people who write to me with this question are usually journalists, NGO workers, humanitarian aid workers, someone going to set up or repair something for work, and above all, Ukrainians from the diaspora who cross in and out through Poland to see family. So I'm writing to you, not for a tourism brochure. First, no beating around the bush: the Spanish Ministry of Foreign Affairs recommends not traveling to Ukraine under any circumstances, and its travel advisory page (updated June 3, 2026) takes precedence over anything you read here. Second: if you still go, mobile data stops being a convenience and becomes a matter of safety, because air raid alerts are received via app.

Ukraine today: war, martial law, and curfew

How do I get connected in Ukraine? With a local eSIM activated before crossing the border and your home line as a backup. Since January 2026, EU roaming applies in Ukraine, but with data limits; with blackouts and air raid alerts via app, it's better to carry two networks, not one.

Ukraine is at war and under martial law since February 2022. That's not a bureaucratic nuance: it changes what you can do, where you can be, and at what time. Martial law and mobilization are extended in blocks of 90 days by a vote of the Rada, so the expiration date you see today will have changed in three months. Always check it on the Foreign Affairs advisory page, not on a blog.

There is a curfew across the country, with different hours depending on the region. In Kyiv it's usually from 00:00 to 05:00; in the oblasts near the front line it starts much earlier and is much stricter. During those hours you cannot be on the street without a special permit, and that includes going from the train to the hotel. Plan your arrivals with a buffer: a delayed train can leave you stranded at a station until five in the morning.

Two other things to keep in mind. One: it is forbidden to photograph or publish images of military infrastructure, air defenses, or impact sites, and publishing them with geolocation can get you into serious trouble with the police. Two: if you are Spanish, register in the Consulate's Traveler Registry before entering. Adult men must always carry a passport or national ID to prove nationality at military checkpoints.

Staying connected is not optional: alerts arrive on your phone

This is the point I want you to take away even if you read nothing else. In Ukraine air raid alerts are sent via a mobile app. Yes, sirens still sound in cities, but the siren doesn't tell you what is approaching, where from, or how long it will last. The app does, and in many towns and on roads there is simply no siren to hear. Without data, you won't know.

The Ministry of Foreign Affairs expressly recommends installing the free alert app «Тривога» (Trivoga / Air Alert), available for Android and iOS, which sends real-time warnings by region. Many people supplement it with the Telegram channels of the oblast they are in and, in Kyiv, with the municipal app Kyiv Digital. The official public services app Diia also pushes useful notifications. All of this works with data: if you lose your connection, you lose your warning.

The rule I follow and that several correspondents have repeated to me: your phone with data and a battery above 50% are part of your safety gear, just like a flashlight. This is not a tourist concern.

From this comes a practical consequence that almost nobody explains: having only one connection method is a single point of failure. If your only line is your local carrier and its local network partner goes down, you are blind. If your only line is a Ukrainian SIM and you lose it during a move, same thing. Two active profiles on the same phone cost little and solve a lot.

You enter by land: what happens to your phone at the border

Ukrainian airspace has been closed since February 2022 and there are no commercial flights. You enter by land: mainly from Poland (the Medyka, Korczowa or Shehyni crossings, and the train from Przemyśl), and also from Romania, Moldova, Slovakia and Hungary. For Spanish citizens you need a passport —your ID card is not valid— and proof of financial means: the Ministry of Foreign Affairs mentions around €300 plus €50 per day of stay.

The border is slow. Several-hour waits at land crossings are normal, and on weekends or holidays they can be much worse. The overnight train Przemyśl–Kyiv takes around 10 to 12 hours including border control, which is done on the train itself.

And now for what concerns us: at the crossing your phone switches networks. You are connected to a Polish carrier (Play, Orange, Plus, T-Mobile) and suddenly you switch to Kyivstar, Vodafone Ukraine or lifecell. That switch is not always clean. It is common to be without data for twenty minutes just when you want to let people know you have crossed. Three tips:

• Activate and test your Ukrainian eSIM before crossing, using Polish Wi-Fi. Do not install anything in the border queue.
• Leave network selection on automatic and restart your phone if it does not connect after ten minutes.
• Download offline maps of the area and save screenshots of tickets, addresses and contacts.

The Ukrainian network: operators, coverage, and national roaming

There are three operators with their own network: Kyivstar (the largest, about 25 million users), Vodafone Ukraine, and lifecell. All three provide widespread 4G/LTE in cities, oblast capitals, main roads, and most rural areas in the west and center. Commercial 5G is not widely deployed: during the war, the priority has been keeping 4G running, not launching new technology.

What really sets Ukraine apart is something you won't see in any other European country: national roaming. A week after the 2022 invasion, the three operators agreed that their customers could connect to each other's networks when their own was down or damaged. It has been extended ever since and is activated by zone when needed. It's not a permanent, universal service — it's worth being clear about that — but it has proven to be one of the most effective resilience measures of the war.

Context helps you understand the scale of the achievement: over 4,000 base stations and about 60,000 km of fiber have been damaged. Even so, in most of the territory controlled by Ukraine, there is signal. Where there isn't, or where it's intermittent, is near the front line, in recently liberated areas, and in border zones with military restrictions. There, don't count on coverage and plan accordingly: meeting points, fixed times, and someone outside who knows your route.

Blackouts and antennas: the problem nobody tells you about

If you ask me what the number one cause of losing signal in Ukraine is, the answer isn't electronic warfare or a lack of antennas: it's the power. Attacks on the power grid cause scheduled and unscheduled outages, and an antenna without electricity stops transmitting as soon as its battery runs out.

The operators have poured a lot of money into backup power. Kyivstar has invested over 2,300 million hryvnias in energy independence, Vodafone Ukraine about 2,000 million, and lifecell around 1,500 million. Together they have bought about 15,000 generators; lifecell-Datagroup also installed 2,000 generators and over 120,000 lithium batteries. It's a huge effort.

And even so, it's not enough. The regulator required 10 hours of operation without grid power, and the operators haven't managed to meet it: in December 2025, outages at lifecell facilities lasted an average of 8 to 12 hours, and by early 2026 they exceeded 16 hours a day in some spots. In fact, the sector has asked to lower the requirement from 10 to 6 hours. Translated: in winter, and during long blackouts, there will be times without coverage no matter what plan you have.

What to do about this, in practice:

1. Carry a large power bank, 20,000 mAh or more, and charge it whenever you have an outlet, even if you're at 80%.
2. Keep your phone above 50%. Dropping below 20% during a blackout is a bad place to be.
3. Have a car charger and, if you're staying for weeks, a small portable power station.

The four ways to get connected, compared

The options are the same as always, but here they're judged by a different standard: it's not about which is cheapest, it's about which fails the least and which you can have working the minute you land — or cross the border — without depending on an open store.

The conclusion I draw is different from a normal destination. Here it's not about choosing one and discarding the rest: it's about stacking two independent layers. A local eSIM for daily data, your home line active underneath for calls, bank SMS, and as an emergency network if the other fails. And WiFi, when available, for downloading maps and making backups. In December 2023, a cyberattack left Kyivstar's 25 million customers without service for hours; anyone with a second line stayed connected.

Your local plan: what changed on January 1, 2026

Here's a big update, and I have to tell you even if it costs me sales. Since January 1, 2026, Ukraine and Moldova are part of the EU roaming zone — the famous "Roam Like at Home." That means your local plan works in Ukraine at domestic prices, with no roaming surcharges, just like you were in Lisbon. The zone now covers 32 countries.

Before you close the tab, here's the fine print, which matters a lot for this destination:

• Fair use policy. Your carrier can cap your roaming GB, especially on prepaid and low-cost plans. Many give you a data allowance that's much smaller than what you get at home.
• Check with your carrier before you leave. The regulation is mandatory, but each company applies it with its own terms and timelines.
• If you're not from the EU — and a good chunk of people traveling to Ukraine for work aren't — this doesn't apply to you, and classic roaming is still very expensive.

If you want the details on what you pay outside this bubble, I break it down in how much international roaming costs, and I compare both options head-to-head in eSIM vs roaming. My take for Ukraine: the regulatory change makes your local line an excellent plan B, not necessarily plan A. With a limited data allowance, using maps, video calls, and uploading files, it runs out faster than you think.

Hotel and café Wi-Fi, and the Starlink phenomenon

Ukrainian Wi-Fi has a quirk that surprises everyone who arrives: Starlink is everywhere. Since 2022, thousands of terminals have been deployed in hospitals, town halls, schools, offices, hotels, and cafés. It's very common to walk into a place in Kyiv, Lviv, or Dnipro and see the white dish on the facade and a sign saying there's internet even if the power goes out.

This creates a curious map. During a blackout, the café with Starlink and a generator can have a better connection than your hotel, while the cell tower across the street is dead. Locals who work with journalists and volunteers know this and advertise it. Just ask directly: "Generator and Starlink?" That's a normal question there.

That said, don't build your trip around Wi-Fi. It depends on the venue, the generator's fuel, and whether you can be inside — and with curfew, you can't at night. Public Wi-Fi is also, well, public Wi-Fi: always use a VPN for your email, your bank, and your work communications. In a country at war, this isn't textbook paranoia; it's basic hygiene.

And pocket Wi-Fi? In Ukraine, I don't see the point: it's one more device to carry in a country where battery life is gold, and it doesn't solve anything that a data profile on your own phone can't handle better. I explain this calmly in eSIM vs pocket Wi-Fi.

Local SIM: real prices from Kyivstar, Vodafone, and lifecell

The Ukrainian prepaid SIM is cheap and works well. The starter pack usually costs between 50 and 100 UAH, and with a plan you're looking at around 300–400 UAH (roughly 6–8 €, with the exchange rate hovering around 45–50 hryvnias per euro; check it on the day you travel). You buy it at carrier stores, shopping malls, and kiosks, and you need a passport: subscriber registration is mandatory and has been tightened during the war.

Prices are indicative for 2026; carriers have raised them several times during the war, so confirm on their website. The downside of the local SIM isn't the cost — it's the timing: you arrive at night, with curfew, and the stores are closed. Right in those first hours, when you most need to let people know you're okay, you have nowhere to buy one. If you're staying for months and need a Ukrainian number for banking or official procedures, go ahead and buy one anyway: it's worth it. I compare both routes in eSIM vs local SIM.

How much data you need and what to pack

An eSIM is a downloadable card that lives inside your phone — no plastic. Here, its advantage isn't convenience, it's time: you activate it from home and cross the border already connected, without needing a store to be open. And since it coexists with your local line, it gives you those two layers I mentioned. You'll find the specific plan and coverage details in my eSIM guide for Ukraine.

And the short list of what I carry, adapted for this destination: a 20,000 mAh or larger power bank, car charger, spare cable, the alert app installed and tested before you enter, offline maps downloaded, a VPN, and the consulate and local contact phone numbers also written down on paper. When the power goes out and your phone is at 4%, paper works.

Conclusion

Here's the bottom line. Ukraine is not a tourist destination right now and the Foreign Office advises against travel; if you're going, it's because you have a compelling reason. In that case, connectivity is safety equipment: air-raid alerts come through an app, airspace is closed and you enter by land with your phone hopping networks at the border, the Ukrainian network holds up thanks to national roaming between operators, and the real enemy of your coverage is blackouts. Since January 2026 your local plan works there without surcharges, with a data cap, and a local SIM costs 300–400 UAH but requires an open store and a passport.

My practical recommendation is simple: two layers of connection and a massive battery. Keep your local line active as a backup and carry your daily data on an eSIM for Ukraine that you activate from home, before you cross. When the power goes out and the rest of the carriage loses signal, you'll be glad you spent five minutes on this. Take care of yourself.
