The best eSIM for a Balkan trip: one plan for eleven borders (2026)
The best eSIM for a Balkan trip is a single regional plan: the Kudo Europe + Region eSIM roams across partner networks in all 46 covered countries, including Albania, Bosnia, Serbia and Montenegro, with prices starting at €1.20. When you cross a border the phone picks up the new network on its own, usually within a minute. Kosovo is handled separately and explained below.
The Balkans reward the travelers who keep moving: breakfast in Sarajevo, a border queue before lunch, sunset over the Bay of Kotor. The phone bill punishes exactly the same behavior. Half the region is outside the EU, so every border you cross can flip your phone from a friendly EU rate to an off-plan roaming zone without warning. The fix is not six local SIM cards. It is one regional eSIM that treats the peninsula as a single place.
Why the Balkans break normal roaming
EU "roam like at home" covers Croatia, Greece, Bulgaria, Romania and Slovenia. It does not cover Albania, Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia or Kosovo. A road trip from Dubrovnik to Tirana can cross four pricing regimes in one afternoon, and the worst of them bill by the megabyte. Buying a local SIM at each border costs time, passports scans, and a new number nobody has.
One eSIM, the whole region
The Europe + Region eSIM from Kudo covers 46 countries with a single installation, and crucially it includes the non-EU Balkans: Albania, Bosnia and Herzegovina, Serbia, Montenegro and North Macedonia, alongside Croatia, Greece, Bulgaria, Romania, Slovenia and Turkey. You cross the border, the eSIM switches network, and nothing else changes.
- Fixed plans from 1 GB at €1.20 up to 100 GB, most with a generous 45-day validity.
- 60-day options for slow overland trips, rare in the industry where 30 days is the norm.
- Unlimited daily-allowance plans for 3, 7, 14 or 30 days from €8.50.
- Validity starts when the eSIM first connects abroad, so you can buy it weeks before the trip.

Explore the Balkan eSIMThe Kosovo exception, handled honestly
Here is the detail most eSIM sellers bury: regional Europe plans, including this one, do not work inside Kosovo. Kosovo's networks sit outside the big regional roaming agreements. If your route includes Prishtina, Prizren or Peja, add the dedicated Kosovo eSIM: 13 GB for 27 days at €20 or 20 GB for 30 days at €26.99. Your phone holds both eSIMs at once and you switch in seconds.
Adding Kosovo to the route?
The dedicated Kosovo plan covers what regional eSIMs cannot.

Frequently asked questions
Does one eSIM really work across borders automatically?
Yes. The Europe + Region plan roams across partner networks in all 46 covered countries. When you cross a border the phone picks up the new network on its own, usually within a minute.
Which Balkan countries are covered?
Albania, Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia, Croatia, Greece, Bulgaria, Romania, Slovenia and Turkey are all covered. Kosovo is the exception and has its own dedicated plan.
What if I stay mostly in one country?
Single-country plans are often cheaper for a one-stop trip: Albania from €2.89, Greece from €2.75, North Macedonia from €1.50. The regional plan wins as soon as your route crosses two or more borders.
Can I keep my WhatsApp number?
Yes. Your regular SIM stays in the phone and WhatsApp keeps using your existing number; the eSIM only carries the data.
