You land in Dubrovnik in two weeks. The plan is Mostar for a day, then down the coast to Kotor, and maybe on through Albania and Kosovo before flying home from Skopje or Belgrade. Your Europe eSIM says 34 countries, which sounds like plenty. It will carry you as far as the first Bosnian checkpoint and no further, because Croatia is inside the plan and every country after it on that route is not.
What follows is the route in order: where the plan goes dark, what to install before each crossing, the half minute line switch, and the honest Kosovo picture. Every price is what we read on our own pages and the operator sites on 14 September 2026.
Which Balkan countries does the Europe eSIM cover?
Our Europe plan covers 34 countries. Of the ones a Balkans loop touches, Croatia, Slovenia, Greece, Bulgaria, Romania, Hungary and Turkey are in. Bosnia and Herzegovina, Montenegro, Serbia, Kosovo, North Macedonia and Albania are not, and neither are Andorra, Monaco, San Marino, Ukraine or Moldova.
It is the same gap on nearly every Europe plan we checked on 14 September 2026. Orange Holiday Europe lists none of the six. Holafly's Europe plan lists none either, and its Balkans plan carries five and drops Kosovo, as Nomad's does. Read the country list, never the country count.
| Country on the route | In the 34 country Europe plan | What to install instead | From, read 14 Sep 2026 |
|---|---|---|---|
| Croatia, Slovenia, Greece, Bulgaria, Romania, Hungary | Yes | Nothing extra | $1.99 for 1 GB over 7 days |
| Bosnia and Herzegovina | No | Bosnia plan, BH Mobile | $1.90 for 1 GB over 1 day |
| Montenegro | No | Montenegro plan, m:tel CG and T-Mobile | $1.53 for 1 GB over 7 days |
| Albania | No | Albania plan, Vodafone and One Albania | $1.29 for 1 GB over 1 day |
| Kosovo | No | Kosovo plan, fixed data only | $5.99 for 1 GB over 7 days |
| North Macedonia | No | North Macedonia plan, Telekom.mk | $1.74 for 1 GB over 1 day |
| Serbia | No | Serbia plan, Telenor as our page lists it | $1.29 for 1 GB over 1 day |
Why EU roaming ends at the Croatian border
Roam Like at Home is an EU rule. The Commission's consumer page on roaming lists the EU countries plus Iceland, Liechtenstein and Norway, and now Ukraine and Moldova, then says other countries are not covered. Nothing in the Western Balkans is on it. A home SIM either bills you for roaming there or has no data. One traveller on the TripAdvisor Kotor forum reported UK O2 data dying at the Montenegro border while a Vodafone bolt on kept working.
Two other agreements confuse people. Since 1 July 2021 the six Western Balkan states have charged each other's customers no roaming surcharge, under a deal the Regional Cooperation Council announced on 2 July 2021. That is for subscribers of the local operators, on fair use. It says nothing about your home SIM or a travel eSIM.
Then on 6 December 2022, at the Tirana summit, EU and Western Balkan operators signed a voluntary declaration. From 1 October 2023, 1 GB inside a special roaming offer cannot cost more than €18, with prices close to domestic as the aim for 2027. Voluntary is the word to hold onto. European Western Balkans reported on 2 March 2026 that no Western Balkan economy is inside the EU roaming area yet. Your home plan in Montenegro therefore costs anything from €18 a gigabyte to switched off, against a $1.53 Montenegro plan.
What to install before you leave
Install every plan at home on Wi-Fi. Our country plans cover one country each, and every page says the same thing: crossing a border needs a plan for that country or a regional plan. They sit on the phone switched off, and validity starts when the plan first connects, so an installed Bosnia plan waits until you cross.
The Europe plan comes in two shapes. Fixed data runs from $1.99 for 1 GB over 7 days up to 50 GB for 30 days at $33.99, and it includes France and Turkey. The unlimited plans start at $1.29 for one day, with 1 GB per day at full speed then up to 1 Mbps, or 3 GB per day from $2.59. Those run on a different 35 country area that excludes France and Turkey and adds Ukraine, Moldova and San Marino. If your loop ends in Istanbul, that exclusion decides which Europe plan you buy.
Day clocks keep running on the other line A Croatia Destination Expert's thread on TripAdvisor, closed in May 2026, turned on one discovery. A day based unlimited plan keeps counting days while you are switched to another eSIM. Ours behave the same way. A three day Europe unlimited plan does not pause on the Tuesday you spend in Mostar. For a loop with day trips, fixed plans with 7 or 30 day validity waste less.
The border routine on iPhone and Android
Nothing reconnects on its own at a border the plan does not cover. Several ranking guides say a regional eSIM switches automatically at every crossing, and that is true only inside that plan's list. Moving from the Europe plan to a country plan is a manual change of data line.
- At home, install each plan on Wi-Fi. iPhone: Settings, Cellular, Add eSIM. On a Pixel it is Settings, Network and internet, SIMs, Add SIM, and on Samsung it is Settings, Connections, SIM manager, Add eSIM. Label each line by country and leave it off.
- Home line: Data Roaming off. Keep Default Voice Line on your home number so calls and bank codes still arrive.
- In Croatia, turn the Europe line on with Data Roaming on for that line only, then Settings, Cellular, Cellular Data, choose it. Switch Allow Cellular Data Switching off; on Samsung, Data during calls off.
- Pulling away from the Bosnian checkpoint: Settings, Cellular, tap the Bosnia line, Turn On This Line, Data Roaming on. Then Cellular Data, choose Bosnia. Pixel: Network and internet, SIMs, Mobile data, pick the Bosnia line.
- Turn the Europe line off. iPhone: tap it, Turn On This Line off. Pixel: Network and internet, Mobile network, select the SIM, Use this SIM off.
- Give it a minute. Bars with no data often clears with one pass of airplane mode. Kosovo is the exception and needs a manual network pick, covered below.
- Coming back into Croatia, reverse it. One Rick Steves forum user in 2024 toggled by country all trip and reinstalled one plan once.
Dubrovnik to Mostar or Kotor for the day: how much data you need
These two day trips generate most of the forum threads. Both leave the EU for the middle of the day, so the Europe line is off for six or eight hours and a country plan does the work. The small plans fit. Bosnia is $1.90 for 1 GB over 1 day. Montenegro is $1.53 for 1 GB over 7 days, which also covers a second run to Herceg Novi later in the week.
A gigabyte is more than a day trip uses. eSIM sellers put Google Maps navigation at roughly 3 to 5 MB an hour, or 7 to 10 MB with live traffic. Google publishes no figure of its own, so treat those as estimates. Even at double, a day of directions, messages and a few photos to the family group stays well under 1 GB.
Download the offline map anyway. In Google Maps you search the place, tap More, then Download offline map. Driving navigation works offline, without live traffic or alternate routes; transit, cycling and walking directions do not. Do Mostar and Kotor on the hotel Wi-Fi the night before, and the border queue stops mattering.
Croatia into Bosnia: Neum, Metkovic and Bijaca
Three crossings matter, and for Mostar from Dubrovnik you normally use Metkovic to Doljani, or Bijaca to Nova Sela off the A1. The coast road from Split runs through the Neum corridor, Bosnia's short strip of coast. Its two checkpoints, Neum 1 to Klek and Neum 2 to Zaton Doli, sit about 9 km apart. The Peljesac bridge, open since 26 July 2022 and toll free, exists so through traffic can skip them. It does not help if Mostar is where you are going.
Croatia's accession in 2013 made this the EU's external border, so expect a full passport check both ways. The Entry/Exit System started on 12 October 2025 and became fully operational on 10 April 2026, according to the Commission. It records fingerprints, a facial image, and the date and place of each entry and exit. The Commission names no crossings, but Croatia is a Schengen state, so expect the EES routine at its land borders. The Neum corridor is not a formality, whatever a transfer blog says.
gov.uk adds a rule most day trippers never hear: all foreign nationals must register with the police within 72 hours of arriving in Bosnia, and hotels normally do it. Our Bosnia plan runs on BH Mobile, which our page says covers both the Federation and Republika Srpska, with hotspot allowed. It is $2.16 for 1 GB over 7 days and $6.09 for 3 GB over 30 days. The entity split is real. One Rick Steves forum user in May 2026 found a pay as you go eSIM worked in Sarajevo and Trebinje but not in Banja Luka or Mostar.
Croatia and Bosnia into Montenegro: Debeli Brijeg and the live queue pages
From Dubrovnik, Karasovici to Debeli Brijeg is the main crossing, with Vitaljina to Kobila as the smaller coastal option. Transfer company blogs quote summer weekend waits of two to four hours here, and none cites a source, so we will not repeat the number as fact. nakordoni.eu publishes estimated live waits for both crossings from official data, cameras and driver reports, and says queues are shortest on weekdays between 10:00 and 15:00. Check it over breakfast.
Our Montenegro plan runs on m:tel CG and T-Mobile, which is Crnogorski Telekom. It is $1.53 for 1 GB over 7 days and $3.36 for 3 GB over 30 days. One day of unlimited, 3 GB per day at full speed, is $3.32. Our page is plain about weak or dead spots deep in canyons and on remote trails, so the Tara canyon road is where the offline map earns its download.
Montenegro into Albania: Sukobin and Hani i Hotit
Two road crossings: Sukobin to Muriqan on the E851 between Ulcinj and Shkoder, and Bozaj to Hani i Hotit on the E762 out of Podgorica. Both countries sit outside EU roaming, so here you swap one country plan for another rather than losing the Europe plan. Same routine, new line.
Our Albania plan runs on Vodafone and One Albania at $1.29 for 1 GB over 1 day or $3.51 for 3 GB over 30 days. Unlimited starts at $3.89 for a day, with 3 GB per day at full speed then up to 1 Mbps. If you would rather buy at Tirana airport, our Albania SIM card guide covers the passport rule and the counters, with one caveat for a loop. Albanian tourist packs mostly stop at the border.
Albania into Kosovo: what broke in 2026 and what to do
From Kukes the crossings are Morine to Vermice for Prizren, Qafe Morine for Gjakova, and Qafe Prush. The phone problem on the Kosovo side is bigger than a missing country on a list. For most of spring 2026 no mainstream travel eSIM connected there at all. The TripAdvisor Kosovo thread, 26 replies between 6 March and 12 September 2026, is the clearest record of it.
| Date in 2026 | Provider | What the traveller reported |
|---|---|---|
| 28 March | Maya | Did not work in Kosovo |
| 3 April | Airalo | Agent: not currently providing services for Kosovo due to technical issues |
| 1 May | Holafly | Would not connect, support could not fix it |
| 2 and 29 May | 99esim | Connected instantly, at the border on the second trip, brief drops in Prizren |
| 13 and 22 May | GoMoWorld | Worked in Kosovo, Montenegro and Bosnia if activated in the app before entering; slowed after half a day |
| 26 August | Airalo | Vala and IPKO packages on sale again |
| 2 and 3 September | MobiSIM, Airalo | A 25 GB €29.99 MobiSIM regional plan worked; Kosovo is still not in Airalo's Europe package |
Nobody has published a cause. One provider's help notice blamed an unexpected regulatory change in Kosovo and named no regulator; Airalo's agent said technical issues. We found no statement from ARKEP or the government, so the forum claim that Kosovo has blocked global eSIM providers is hearsay. On 14 September 2026 Holafly's Kosovo page still said the destination is currently unavailable.
Our Kosovo plan is fixed data only: $5.99 for 1 GB over 7 days, $13.99 for 3 GB over 15 days, no unlimited option. Our page names Vala, network code 221 01, as the network these plans run on, and lists IPKO, 221 02, as the one to switch to by hand. It says the plan stops at the borders with Albania, North Macedonia, Serbia and Montenegro. The local fallback is the Vala kiosk travellers report in Pristina arrivals; our Kosovo SIM card guide has the €7 SIM and €10 eSIM prices.
Kosovo wants a manual network pick Full bars and no internet is the pattern people report. Go to network selection, turn automatic off, and choose Vala 221 01 or IPKO 221 02 by hand. If the one the phone chose gives nothing, pick the other. Do it while the Albanian line is still live, so you can reach support if neither responds.
Kosovo into North Macedonia and Serbia: the entry stamp rule
South to Skopje is a normal crossing and a normal line switch. Our North Macedonia plan runs on Telekom.mk at $1.74 for 1 GB over 1 day, $1.82 for 1 GB over 7 days and $4.62 for 3 GB over 30 days. Its unlimited version gives 1 GB per day at full speed, then up to 1 Mbps for the rest of that day.
North to Serbia is the one trap on this route that has nothing to do with phones. gov.uk states that Serbia does not consider its crossing points with Kosovo to be official international border crossings. Without a Serbian entry stamp from Belgrade, Nis or Kraljevo airports, or from one of Serbia's other crossings, you are likely to be refused. The advice is to route through a third country. The clean order is Albania, Kosovo, North Macedonia, then Serbia from the south.
Our Serbia plan runs on the network our page lists as Telenor. It is $1.29 for 1 GB over 1 day or $3.42 for 3 GB over 30 days, and unlimited is $3.84 a day with 3 GB per day at full speed. Entering from Bulgaria or Romania instead, both in Schengen since 1 January 2025 according to the Commission, means an EES crossing, and both are inside the Europe plan.
Tourist SIMs that include Western Balkans roaming
For two weeks or more across several of the six, one local tourist pack with a Western Balkans allowance is worth pricing. Keep the rule from the Bosnia TripAdvisor thread, where a poster in about 2023 found his Bosnian prepaid SIM's free regional roaming applied to residents only, under fair use. Only a pack whose page lists a Western Balkans allowance roams. Three do, as read on 14 September 2026.
BH Telecom sells Tourist 1 at 31.70 KM for 40 GB over 10 days and Tourist 2 at 51.70 KM for 100 GB over 30 days. Both are eSIMs with a number, at a maximum of 4G+, for Bosnia and the Western Balkans. Crnogorski Telekom's tourist eSIM is €15 for 500 GB over 15 days, of which 9 GB is usable in the Western Balkans and Croatia. Non Balkan, non EU citizens must show a passport. m:tel Montenegro's Turist 15 carries 9.92 GB for Albania, Bosnia, North Macedonia, Serbia and Kosovo, with no euro price on its page.
The mirror problem applies. A Western Balkans allowance is not EU roaming, so the local pack goes dark when you drive back into Croatia unless its page names Croatia, as only Crnogorski Telekom's does. Our country plans cost $1.29 to $1.90 for a gigabyte day in five of the six, and $5.99 in Kosovo, with no counter and no registration. For more data over more weeks, the local pack wins on volume.
Quick answers
Can I use one eSIM in Croatia and Bosnia and Herzegovina?
Only if the plan lists both countries. Croatia is inside the 34 country Europe plan and Bosnia is not. So you install a Bosnia country plan alongside it and change the data line by hand at Metkovic, Bijaca or Neum. Nothing reconnects on its own at a border the plan does not cover.
Does EU roaming work in Montenegro?
No. Roam Like at Home covers the EU plus Iceland, Liechtenstein, Norway, Ukraine and Moldova, and the Commission's page says other countries are not covered. A home EU SIM in Montenegro bills roaming or has no data. Since 1 October 2023 signatory operators cap 1 GB in special offers at 18 euros, still far above a $1.53 Montenegro plan.
Are there border checks between Bosnia and Croatia?
Yes, full passport checks both ways, including in the Neum corridor. It is an EU external border, and the Entry/Exit System that became fully operational on 10 April 2026 records fingerprints and a facial image for non EU visitors. The Peljesac bridge, open since 26 July 2022 and toll free, lets Split to Dubrovnik traffic skip Neum.
Do I need an eSIM for Montenegro?
You need something that is not EU roaming, because Montenegro is outside Roam Like at Home. That means a Montenegro country plan, a regional plan whose list names Montenegro, or a local tourist SIM such as Crnogorski Telekom's 15 euro eSIM. A plain Europe plan usually stops at Debeli Brijeg, and ours does.
Why is my travel eSIM not working in Kosovo?
First check that the plan lists Kosovo, because most Europe plans do not. In spring 2026 Maya, Airalo and Holafly all had no service there, and Holafly's Kosovo product was still marked unavailable on 14 September 2026. With a plan that does cover Kosovo, turn off automatic network selection and pick Vala 221 01 or IPKO 221 02 by hand.
Which eSIM should I use for a Balkans road trip?
It depends on whether Kosovo is on the route. Holafly's and Nomad's Balkans plans leave Kosovo out, and a TripAdvisor user reported in September 2026 that Airalo's Europe package does too. Our approach is a Europe plan for the EU legs and one country plan for each non EU stop, installed at home and switched on at each border.
Do any Balkan countries ban eSIM?
None of them. The Kosovo gap in spring 2026 was a supply problem: one provider cited an unspecified regulatory change and Airalo cited technical issues, and no regulator statement exists in anything we read. Airalo was selling Vala and IPKO packages again by late August. BH Telecom, Crnogorski Telekom and Vala all sell tourist eSIMs over the counter or online.
