Best eSIM for the Balkans (2026): One Plan for Croatia, Montenegro, Albania, Serbia and Greece

The best eSIM for Balkans trips is a regional plan, because the region straddles the EU roaming line. Wayfarro's Balkans plan covers 11 countries with 10GB for 30 days at $25 and 7 days of unlimited data at $24. Nomad's Balkans plan covers 12 countries and charges $39 for the same 10GB. Wayfarro's prices come straight from its store; Nomad's were checked in October 2026.

Wayfarro is cheaper at every fixed-data size and is the only one of the two selling unlimited plans and long-stay bundles. Nomad's list includes Hungary and Turkey, which Wayfarro's doesn't. Airalo didn't have a Balkans regional page we could read, so it isn't in this comparison.

How to read this table: Wayfarro is cheaper than Nomad at every size the two share, and the gap widens as the plan gets bigger. Nomad sells only fixed data for the region; Wayfarro adds unlimited plans from 1 to 30 days and bundles that run 60, 90 and 180 days. A dash means the provider doesn't sell that exact plan, or we couldn't confirm its US-dollar price. Neither provider names the partner network in each country on its plan page.

Wayfarro's unlimited rows are its Unlimited Lite plans: 1GB a day at full speed, then 512 kbps until the next day. It also sells Unlimited Essential (1GB a day, then 1.25 Mbps) and Unlimited Plus (2GB a day, then 2 Mbps). Seven days costs $29 on Essential and $58 on Plus.

Why EU roaming doesn't get you through the Balkans

Half the region is in the EU and half isn't, and the border between the two runs right through the classic route. Croatia, Slovenia, Greece, Bulgaria and Romania are EU members, so an EU SIM roams there at home rates under the "roam like at home" rules in force since June 2017. Montenegro, Albania, Bosnia and Herzegovina, Serbia, North Macedonia and Moldova are outside that zone, and an EU SIM pays full roaming rates the moment the bus leaves Dubrovnik for Kotor.

The non-EU countries have their own deal. Serbia, Albania, Montenegro, Bosnia, North Macedonia and Kosovo dropped roaming fees between each other on 1 July 2021. That helps if you buy a local SIM in one of them, but it doesn't help an EU SIM, a UK SIM or a North American one, and a local SIM means a passport registration at a shop and a new number.

A regional eSIM ignores the line. Wayfarro's Balkans plan covers five EU countries and six non-EU ones on one profile, which is the whole point of buying it instead of relying on home roaming.

Check the country list before the price

Every provider draws the Balkans differently. Wayfarro's 11 are Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Moldova, Montenegro, North Macedonia, Romania, Serbia and Slovenia. Nomad's 12 are the same minus Moldova, plus Hungary and Turkey.

The gaps that catch people:

• Kosovo: Not on either list. Pristina and Prizren are a day trip from Skopje or Tirana for a lot of travelers, so plan on café Wi-Fi there or a local SIM.
• Hungary: Budapest is a common start or end point for a Balkan loop. It's on Nomad's list and not on Wayfarro's, so with Wayfarro you'd add a Hungary plan to the order.
• Turkey: Same story for Istanbul. Nomad covers it in the regional plan; with Wayfarro you'd pair the Balkans plan with a Turkey plan in the Trip Builder.
• Moldova: Only Wayfarro covers it, which matters if your route runs Bucharest to Chișinău.
• Greece: On both lists. If Greece is the whole trip, the Greece guide compares the single-country plans, which cost less for the same data.

Which Balkans eSIM should you buy?

The best eSIM for Balkans travel depends on the route:

• Ten days on the Adriatic, Split to Dubrovnik to Kotor: 5GB for 30 days at $16 covers maps, ferries and bus bookings for most people. Nomad's 5GB is $25.
• Two to three weeks through the whole loop, Ljubljana to Sarajevo to Belgrade to Sofia: 10GB at $25, or 20GB at $39 if you post a lot. Top up without reinstalling if you run low.
• A week of heavy use, video and video calls every day: 7 days of Unlimited Plus at $58 gives you 2GB a day at full speed. Nomad doesn't sell unlimited for the region.
• A summer working from Tirana, Belgrade or Sarajevo: The long-stay bundles exist for this. 50GB over 90 days is $169 and 100GB over 180 days is $373, on one install.
• A one-day stop in Zagreb or Thessaloniki: 1 day of unlimited is $6. Nobody else in this comparison sells a 1-day Balkans plan.
• Budapest or Istanbul on the itinerary: Nomad's regional plan covers them. With Wayfarro, put the Balkans plan and the Hungary or Turkey plan on one order in the Trip Builder.

What "unlimited" means on a Balkans plan

Every unlimited travel eSIM has a fair-use policy. After a set amount of high-speed data each day, your speed drops until the next day. Wayfarro publishes its limits on the plan page: 1GB a day on Lite and Essential, 2GB a day on Plus, then 512 kbps, 1.25 Mbps or 2 Mbps for the rest of that day.

In practice, 512 kbps still runs Google Maps, WhatsApp and a bus-company booking page. It won't upload a day of Plitvice video. If that's your habit, Unlimited Plus or a 20GB fixed plan is the better buy. Wayfarro allows hotspot on every plan, and a fixed plan can be topped up mid-trip without reinstalling.

The networks you'll land on

Neither provider names its partner network per country, so here's what the networks look like on the ground. Croatia has three: Hrvatski Telekom, A1 and Telemach. Hrvatski Telekom is the largest, with about 2.27 million users at the end of 2018, and A1 is close behind. Along the coast and on the islands all three are fine; the gaps are inland, in the mountains between Split and Sarajevo and on the long stretches of motorway through Slavonia.

Elsewhere in the region, expect the same pattern. Cities, coasts and main roads are well covered. Mountain passes, the Accursed Mountains on the Albania–Montenegro border, the Tara canyon and the Transfăgărășan in Romania are where every network drops. Download offline maps for those days.

Two other things to know:

• Borders by bus take a while. Dubrovnik to Kotor and Kotor to Tirana both cross land borders where buses can sit for an hour. The eSIM switches networks on its own once you're through; if it hasn't after a few minutes, toggle airplane mode.
• Ferries and islands: Hvar, Korčula and the Greek islands have coverage in the towns. Out on the water between them, signal fades on every network.

How to set up a Balkans eSIM

Install at home, switch it on when you land, and leave it on at every border. It takes a couple of minutes:

1. Check your phone is unlocked and supports eSIM. iPhone XS and later, Google Pixel 3 and later, and most recent Samsung Galaxy phones do.
2. Install over Wi-Fi before you fly. Scan the QR code or use the one-tap install link. The step-by-step install guide covers iPhone and Android.
3. Label it "Balkans" so you can find it in settings.
4. When you land, set the regional eSIM as your mobile-data line and turn on Data Roaming for it. Travel eSIMs are roaming profiles, so data won't connect without this.
5. At each border, do nothing. The eSIM picks up a partner network in the next country on its own.
6. Keep your home SIM on for calls and texts with its own data roaming off, so bank verification codes still arrive.

Wayfarro's validity starts when the eSIM first connects in any covered country, not when you install it, so buying a week early costs nothing.

Bottom line

Wayfarro is the best eSIM for Balkans trips on price at every data size, and the only one here with unlimited plans and long-stay bundles. Nomad's regional plan is the one to pick if Budapest or Istanbul is on the same ticket and you'd rather not add a second plan. Either way, check the country list first: Kosovo is missing from both, and Hungary and Turkey are the usual gaps on Wayfarro's. See Wayfarro's Balkans eSIM plans, or build the whole route, extra countries included, in the Trip Builder. If the trip is Greece alone, the Greece eSIM plans cost less for the same data.
