Best eSIM for Montenegro (2026): Kotor, Budva, Prices and Which Plan to Buy

The best eSIM for Montenegro is Wayfarro if you want unlimited data, and a toss-up between Wayfarro and Nomad on fixed plans. Seven days of unlimited costs $20 at Wayfarro, $23 at Nomad and $33.50 at Airalo. On fixed data, Wayfarro and Nomad both charge $4 for 1GB and the same again at 5GB, 10GB and 20GB. Wayfarro's prices come straight from its store; Nomad's and Airalo's were checked in October 2026.

The bigger point for most visitors is that Montenegro isn't in the EU. Your EU plan's free roaming ends at the Croatian border, so a Montenegro eSIM, or a Balkans plan that covers Croatia and Albania too, is the thing to sort before the bus leaves Dubrovnik.

How to read this table: Wayfarro and Nomad are level on every fixed size up to 20GB, and Nomad is cheaper on 50GB. Wayfarro is the cheapest or tied on unlimited at every length, and the only one with a 1-day plan or anything longer than 10 days from Nomad. Airalo costs more than both at every length it shares. A dash means the provider doesn't sell that exact plan, or we couldn't confirm its US-dollar price. Airalo's page listed only unlimited plans when we checked.

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 $21 on Essential and $33 on Plus. Nomad states its Montenegro rule as 2GB a day at 4G/5G and 1 Mbps after that; Airalo's is 3GB a day at up to 20 Mbps, then 1 Mbps.

Why your EU plan stops working at the border

Montenegro pays with the euro but isn't an EU member, and the roaming rules follow membership, not the currency. Croatia, next door, is in the EU, so an EU SIM roams there at home rates. Cross the border on the Dubrovnik–Kotor road and the same SIM is on full roaming rates, or on nothing if you've switched roaming off.

Montenegro, Serbia, Albania, Bosnia, North Macedonia and Kosovo dropped roaming fees between each other in July 2021, which helps anyone with a local SIM from one of them. It doesn't help an EU, UK or North American SIM. A travel eSIM sidesteps the whole thing, and a regional one keeps working on both sides of the line.

Which Montenegro eSIM should you buy?

The best eSIM for Montenegro depends on the route:

• A long weekend in Kotor and Budva: 3GB for 30 days at $8, the same price as Nomad, covers maps and boat bookings. For heavy use, Wayfarro's 3-day unlimited at $11 matches Nomad's $11.
• A week on the coast, Herceg Novi to Ulcinj: 5GB at $12 for moderate use. For unlimited, Wayfarro's 7 days at $20 is the cheapest here.
• Two weeks including Durmitor and the north: 10GB at $18, with top-ups if you run low. Wayfarro's 15-day unlimited at $35 is the only 15-day plan in the table apart from Airalo's $49.
• A month or a summer working from Tivat or Podgorica: Nomad's 50GB at $35 beats Wayfarro's $41. For unlimited, Wayfarro's 30 days at $69 is the cheaper of the two 30-day plans.
• Montenegro plus Dubrovnik, Mostar or Tirana: The Balkans bundle. 5GB for 30 days at $16 covers eleven countries, and the Balkans eSIM guide compares it with Nomad's.
• A one-day stop from a cruise ship in Kotor: Wayfarro's 1-day unlimited at $5.50. Nobody else in this comparison sells a 1-day plan.

Networks and coverage in Montenegro

Montenegro has three operators: m:tel, Crnogorski Telekom and One Montenegro. m:tel, a joint venture of Telekom Srbija and Telekom Srpske, was the largest in December 2025 with about 41% of subscribers. Crnogorski Telekom, majority-owned by Hrvatski Telekom and so part of the Deutsche Telekom group, had 36%, and One Montenegro, owned by Hungary's 4iG, had 23%. All three run LTE nationally and have 5G on the 700 MHz and 3.5 GHz bands.

Nomad's eSIM runs on m:tel and Crnogorski Telekom, and Airalo's on m:tel. Wayfarro doesn't name the network on its plan page.

Where coverage changes:

• The Bay of Kotor: The steep sides of the bay mean signal comes and goes on the water. On the Kotor–Perast road and in the towns it's fine on every network.
• The Kotor serpentine and Lovćen: The hairpin road above Kotor up to the Lovćen national park has patchy signal, and the views are the point anyway.
• Durmitor and the Tara canyon: The national park, with Bobotov Kuk at 2,523 m, is the thinnest-covered part of the country. Žabljak town has signal; the trails and the rafting stretch of the Tara mostly don't.
• Podgorica, Budva and Tivat airports: All well covered. Tivat airport is a short drive from Kotor; Podgorica is the capital's airport and both are run by Airports of Montenegro.

How to set up an eSIM for Montenegro

Install at home, switch it on when you land or before you cross the 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 travel. Scan the QR code or use the one-tap install link. The step-by-step install guide covers iPhone and Android.
3. Label it "Montenegro" so you can find it in settings.
4. When you arrive, set the Montenegro 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. Keep your home SIM on for calls and texts with its own data roaming off, so bank verification codes still arrive and you don't pay for roaming data by accident.

Wayfarro's validity starts when the eSIM first connects in Montenegro, not when you install it. If you're arriving by bus from Dubrovnik, switch the eSIM's data on as you reach the border and your home SIM's roaming data off.

What to know on the ground in Montenegro

Most trips run along the coast between Herceg Novi and Ulcinj, with Kotor, Budva and Sveti Stefan in the middle. Budva is the centre of the beach-and-nightlife scene and one of the oldest settlements on the Adriatic; Sveti Stefan is the walled islet resort 6 km south-east of it. Kotor's old town is a pedestrian maze where offline maps help as much as data.

Data matters most on the coast road, where buses and taxis are booked by app and the road itself is slow in summer. Up north, Žabljak and the Durmitor trails are where you'll want downloaded maps, and the Cetinje–Lovćen–Kotor loop is a day of thin signal and good photos. Apartment and hostel Wi-Fi is widespread, so a 3GB or 5GB plan goes further here than in a big city.

Bottom line

Wayfarro is the best eSIM for Montenegro for unlimited data and short stays, and level with Nomad on fixed plans; Nomad wins on 50GB. Whichever you pick, sort it before the Croatian border, because EU roaming doesn't follow you in.
