If you are comparing eSIMs for a Balkans trip covering Croatia, Albania, Bosnia, Montenegro, Serbia or North Macedonia, the usual advice does not help much. Most comparison articles rank providers on price and data size, which is the wrong test for this region. In the Balkans the question that actually decides your trip is simpler: does the plan cover the non-EU countries at all?
This guide compares the main options honestly, including where other providers beat us.
Which eSIM is best for the Balkans?
The best eSIM for the Balkans is a regional plan that explicitly lists the non-EU Western Balkans countries, because standard "Europe" plans usually stop at the border. OVOSIM's Balkans plan covers Croatia, Albania, Bosnia, Montenegro, Serbia, North Macedonia, Kosovo, Bulgaria and Greece on one eSIM, and still covers Kosovo, which some platforms have dropped. Airalo, Holafly and Saily also sell Balkans coverage, so compare the exact country list before you buy.
The one thing that decides this comparison
Only Croatia, Bulgaria, Slovenia, Romania and Greece are in the EU. Albania, Kosovo, Montenegro, Serbia, North Macedonia and Bosnia are not. That single fact causes most Balkans connectivity failures:
- An EU or "Europe" plan works fine across Croatia, then stops when you cross into Montenegro or Bosnia.
- A traveller doing Dubrovnik to Kotor to Tirana can lose data at two borders in one day.
- Diaspora travellers driving home from Germany, Switzerland or Austria hit the same wall at the Balkan border.
So the first filter for any provider is not price. It is whether the plan names the specific countries on your route.

Where each provider fits
OVOSIM
Built around this region rather than treating it as one market among two hundred. One plan covers Croatia, Albania, Bosnia, Montenegro, Serbia, North Macedonia, Kosovo, Bulgaria and Greece, so the eSIM keeps working as you cross borders. We are based in Kosovo, which is why the region gets more attention here than it usually does.
Best for: multi-country Balkans routes, and trips where Kosovo is on the itinerary.
Airalo
A large global provider with a wide catalogue and a well-known brand. Good option if you want one account for many future trips rather than a Balkans-specific plan.
Best for: travellers who want a single global provider across many destinations.
Holafly
Known for unlimited-data plans, which suits heavy users who do not want to think about a data cap.
Best for: heavy data users who prefer unlimited over a fixed allowance.
Saily
A newer entrant with straightforward pricing and a simple app.
Best for: travellers who want a simple, budget-focused option.
Kosovo, the part most comparisons skip
Kosovo is the country most likely to break a Balkans plan. Some eSIM platforms that Kosovar travellers and diaspora used to rely on have quietly dropped Kosovo coverage, which is frustrating when it is the whole reason for the trip.
OVOSIM still covers Kosovo directly on the Kosovo Telecom network, with coverage across Pristina, Prizren, Peja and the main towns.
One honest note so nothing surprises you: on first install the eSIM occasionally does not pick up signal for the first few minutes after landing. Toggle airplane mode on and off, wait a moment, and set the APN in your phone's optional eSIM settings. It connects after that. It is a setup step, not a fault.
How to actually choose
- Write down every country on your route, including short crossings like the Neum corridor between Split and Dubrovnik, which passes through Bosnian territory.
- Check the provider's country list names each one. "Europe" and even "Balkans" in a plan title are not enough.
- Decide regional or single-country. Three or more countries usually means a regional plan. One country for a long stay may be cheaper on a local SIM.
- Size the data for the trip length. Diaspora summer visits run two to three weeks, so plan in weeks rather than days.
- Install before you fly and keep the line switched off until you land, so the validity clock starts when you arrive.
Recommendations by trip type
| Your trip | What we would recommend |
|---|---|
| Croatia, Montenegro, Bosnia coastal road trip | A regional Balkans plan, because two of the three are non-EU |
| Visiting family in Kosovo plus the Albanian coast | A regional Balkans plan that explicitly includes Kosovo |
| One country, several weeks, family on the ground | A local SIM is often cheaper; an eSIM still helps on arrival day |
| Croatia or Greece only | A standard EU or Europe plan is enough, since both are EU members |
| Heavy streaming across the region | An unlimited plan, from us or Holafly |
Frequently asked questions
Does a standard Europe eSIM work in the Balkans?
Usually only in the EU members: Croatia, Bulgaria, Slovenia, Romania and Greece. Albania, Kosovo, Montenegro, Serbia, North Macedonia and Bosnia are outside the EU and are commonly excluded, so check the country list.
Which eSIM covers Kosovo?
OVOSIM covers Kosovo on the Kosovo Telecom network. Some platforms have dropped Kosovo, so verify it is named on the plan before buying from anyone.
Is one regional plan better than separate country eSIMs?
For three or more countries, yes, because you avoid swapping eSIMs at every border. For a single destination, a country plan or a local SIM can be cheaper.
Do I need a VPN in the Balkans?
No. Internet is unrestricted across the region and all major apps work normally.
Can I keep my home number?
Yes. The eSIM handles data only, so your home SIM stays active for calls and WhatsApp.
The bottom line
For the Balkans, the deciding factor is coverage of the non-EU countries, not price per gigabyte. If your route stays inside Croatia or Greece, almost any Europe plan works. The moment Albania, Bosnia, Montenegro, Serbia, North Macedonia or Kosovo is involved, you need a plan that names them, and Kosovo in particular is worth checking twice.
