Best eSIM for Ukraine (2026): Networks, EU Roaming and Staying Connected During Outages

Travel to Ukraine in 2026 is mostly essential travel: journalists, aid and NGO workers, business visitors and people visiting family. Before anything else, check your government's travel advice, which in many countries still advises against travel because of the war. Ukrainian airspace remains closed to commercial flights, so most people enter by train or road from Poland, Moldova, Romania, Slovakia or Hungary. For connectivity, two things matter: Ukraine joined the EU's Roam Like at Home area on 1 January 2026, and strikes on the power grid can still take parts of the mobile network offline. co:sim's Ukraine eSIM lists all three national operators, Kyivstar, Vodafone Ukraine and lifecell (4G).

#Do you still need an eSIM for Ukraine?

• EU or EEA phone plan: since 1 January 2026, EU and Ukrainian operators apply Roam Like at Home, so your home allowance works in Ukraine under the same fair-use rules as elsewhere in the EU (European Commission, ComReg). An eSIM is still useful as a second, independent line or if your allowance is small.
• UK, US, Asian or other plans: EU roaming rules do not help you. A prepaid eSIM is usually far cheaper than international roaming.
• Everyone: a data eSIM that can use more than one Ukrainian network gives you resilience when one operator's towers lose power.

The Ukraine eSIM lists Kyivstar, Vodafone and lifecell (4G). At the time of writing (October 2026):

Validity starts at first connection, you have 90 days to install, and some plans can be topped up.

Crossing from Poland or another EU country? The Europe (35 areas) and Europe (42 areas) plans include Ukraine alongside Poland and most of Europe, so your data keeps working on both sides of the border.

#Staying connected during power outages

Russian strikes on energy infrastructure continue to cause scheduled and emergency power cuts. When mains power fails, mobile towers run on batteries and generators, but capacity can drop and some sites go offline during long outages. Practical steps:

1. Carry a large power bank and keep your phone charged whenever power is available.
2. Install an air-raid alert app and follow official local channels for alerts and shelter locations.
3. Download offline maps of the cities you will visit, plus the location of the nearest shelters.
4. Keep key documents offline: tickets, contacts, addresses and emergency numbers.
5. Know the "Invincibility Points" (Punkty Nezlamnosti), public spaces set up to offer power, heating and connectivity during outages.
6. Have more than one way to connect: an eSIM that can switch between operators, plus Wi-Fi where available.

#Coverage in Ukraine

Kyiv, Lviv, Odesa, Dnipro and other cities have wide 4G coverage when the grid is stable. Coverage near the front line and in areas affected by fighting is unreliable or absent, and travel there is subject to additional restrictions. On long train journeys, expect gaps between towns.

#How to set it up

1. Check your phone supports eSIM and is carrier-unlocked.
2. Buy and install on Wi-Fi before you set off, ideally before the border crossing.
3. Set the eSIM as your mobile data line with data roaming on.
4. If you are relying on an EU plan too, label both lines clearly so you can switch quickly.
5. After crossing, check the eSIM has connected and load a web page.

#FAQ

#Does EU roaming work in Ukraine now?

Yes. Ukraine joined the EU's Roam Like at Home area on 1 January 2026, so EU and EEA plans roam at home rates, subject to the usual fair-use rules.

#Which networks does co:sim use in Ukraine?

The Ukraine plans list Kyivstar, Vodafone Ukraine and lifecell, all on 4G.

#Will my eSIM work during a blackout?

It works as long as a nearby tower has power. Many towers have backup power, but coverage can degrade during long outages, so carry a power bank and keep offline copies of essentials.

#Can I use one eSIM for Poland and Ukraine?

Yes. The Europe (35 areas) and Europe (42 areas) plans include both countries.

Connectivity in Ukraine is better than many visitors expect, but it depends on the power grid. Check official travel advice, install before the border, and plan for outages.
