About this eSIM

T-Mobile and m:tel CG both cover Montenegro on 4G LTE and 5G, which is a strong position for a country this small and this vertical. The practical story of using a phone here is written by the landscape: a coast squeezed between mountains and sea, a bay ringed by cliffs, long road tunnels, and a northern half where the roads climb into canyons. Expect a fast connection most of the time and sudden, brief silences in very specific places.

Getting online when you land

Most visitors arrive at Tivat, a small airport a short drive from the bay, or at Podgorica. Some fly into Dubrovnik and drive south, which is worth flagging: that route starts in Croatia, and a Montenegro plan only starts working once you have crossed the border. If that is your arrival, sort your route and border expectations before you leave the airport.

For a domestic arrival, the routine is simple. Install the profile at home on wifi, leave it off, then switch it on after landing and give it a minute or two to attach. Make it your data line, keep your home number on the primary SIM for calls, and disable roaming on that home line.

Tivat in particular rewards being connected on arrival: the airport is small, taxis wait outside, and the drive around the bay to Kotor or Budva involves narrow coastal road where you would much rather have the map running than be reading signs.

The networks you'll be on

Both T-Mobile and m:tel CG offer 5G here, and you will see it in the larger towns and along the busier parts of the coast. Elsewhere you will be on 4G/LTE, which is more than enough for everything a traveller does.

Your phone selects a network without your involvement and will move between them as you drive. In the mountains it is common to watch the signal indicator swing between full and nothing over a couple of kilometres; that is the terrain, not the plan. If a connection seems stuck in a fringe spot, moving twenty metres to where you can see more sky often does more than any setting you could change.

Where coverage holds, and where it thins

Consistently good: the coastal strip from Herceg Novi through Kotor and Budva down to Bar and Ulcinj, the Podgorica area, Tivat and Cetinje, and the main road corridors linking them.

Unreliable in ways worth planning for: the serpentine climb from Kotor up toward Lovćen, where the switchbacks alternate between exposed and shadowed by rock; the Tara canyon and the rafting stretches at the bottom of it, where the walls simply block everything; the higher trails in Durmitor above Žabljak; the Piva and Morača canyon roads; and the forest interior of Biogradska Gora.

Tunnels deserve their own mention. The long tunnel that links Podgorica to the coast, and the shorter tunnels around the bay, will cut a call cleanly. So will the ferry crossing at the narrows between Kamenari and Lepetane, though only for the few minutes it takes. Ostrog monastery, built into a cliff face, is another place where a phone goes quiet and stays that way while you are inside.

Boat trips around the bay stay connected close to shore; head out past the mouth toward open water and that changes.

What you'll actually use data for here

Driving, above all. Montenegro is a hire-car country, and the roads reward live navigation: one-lane sections through old towns, the difference between the tunnel route and the mountain route, and parking that fills up early in the coastal towns in summer. Live traffic on the coast road in high season is genuinely worth having, because the queues into Budva and around the bay are substantial.

Bookings are the other constant. Boat trips to Our Lady of the Rocks, rafting slots on the Tara, restaurant tables in Kotor's old town, and apartment check-ins that happen by message with a host who is not on site. Being reachable is most of the value.

Then translation, which is less needed than in some countries since English is widely spoken along the coast, but useful for menus and signage inland; ferry and bus timetables, which change seasonally; and weather, which differs sharply between the coast and the northern mountains on the same day.

Before you fly

Check the handset is unlocked and eSIM capable, and install the profile before departure rather than at the airport.

Download an offline map of the whole country. It is small, and it covers the canyons and mountain roads where live routing gives up. Screenshot your accommodation address and the host's phone number, because apartment arrivals in the old towns often involve finding an unmarked door down an alley with no car access.

If your trip crosses into Croatia, Bosnia or Albania, which is common from here, remember that a Montenegro plan stops at the border and arrange coverage for those countries separately.

Take a car mount and charger. The driving days are longer than the map suggests, since average speeds on the mountain roads are low, and navigation plus photos will drain a phone before you reach the next town.

Unlimited runs at full speed up to a fair-use limit, then continues slower.

Before you buy

Important to know

This is a data-only eSIM. It carries no calls or SMS on its own number.
Your existing number stays on your primary SIM, so calls and verification texts keep working.
Your phone must support eSIM, and some carrier-locked phones cannot install one.
Signal varies with location, terrain, congestion and your handset. Dense urban areas are consistently better served than remote ones.
5G only works where the host network has deployed it and your phone supports it. Everywhere else it falls back to 4G LTE.
The eSIM selects a host network automatically. You cannot pick or switch between them.
Unlimited plans run at full speed up to a fair-use limit, then continue at a reduced speed. Read the fair usage policy

Frequently asked questions

Does an eSIM work in Montenegro?

Yes. Your Montenegro eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. The host networks it can use are m:tel CG, T-Mobile. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere.

Do I get 5G in Montenegro?

Yes, where it has been deployed. 5G runs on m:tel CG, T-Mobile in Montenegro, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location.

Do I need to register with the police in Montenegro?

Yes. All visitors must be registered with the local tourist office or police within 24 hours of arrival. Hotels and many holiday lets do it for you; in private accommodation you may have to do it yourself. Failing to register can mean a fine, detention or a court appearance, so confirm with your host before you arrive.

Does time in Montenegro count towards my Schengen 90 days?

No. Montenegro is not in the Schengen area, so days spent there don't count towards your Schengen allowance, and the reverse is also true. Montenegro has its own limit of 90 days in any 180-day period. Make sure your passport is stamped on entry and exit as proof of your dates.

Why does my phone show Telekom instead of T-Mobile in Montenegro?

The network listed as T-Mobile is run by Crnogorski Telekom, part of the Deutsche Telekom group through Hrvatski Telekom. It replaced its separate T-Mobile and T-Com brands with a single "T" brand in 2012, so Telekom branding is normal. This eSIM uses that network and m:tel CG, switching between them automatically.

How do I avoid being overcharged by taxis in Montenegro?

Use licensed taxis with a roof sign showing the company name and number, and agree the fare or rate per kilometre before setting off. Taxi apps show prices upfront. At Podgorica airport, take licensed taxis from outside the terminal or check your pre-booked driver is allowed to pick up there.

What is the emergency number in Montenegro?

Dial 112 for police, ambulance and fire services. It's a voice call, and this eSIM is data only, so keep your home SIM switched on alongside it. In the mountains, if you have no signal, move to higher open ground before calling, and always tell someone your route before a hike.

How much data do I need for 7 days in Montenegro?

For 7 days in Montenegro, Viasimo sells 1 GB for $2.29 and unlimited data for $17.00. Our sizing recommendation, not a measurement: maps, messaging and the occasional lookup, about 1 GB a week; maps, social, photos and some browsing, about 3 to 7 GB a week. The data calculator on this site works it out from how you actually use your phone.

Know before you go

Montenegro: what to know before you land

In Montenegro this eSIM uses Crnogorski Telekom, the Deutsche Telekom-group network listed as T-Mobile, and m:tel CG, with 5G in the bigger towns. Two rules catch visitors out: you must be registered with the police or tourist office within 24 hours of arriving, and Montenegro sits outside Schengen, so your passport needs stamping on entry and exit.

Emergency: 112
Plugs: CF 230V
Currency: Euro (EUR)

Crnogorski Telekom and m:tel CG: the networks behind your eSIM

The network listed as T-Mobile belongs to Crnogorski Telekom, Montenegro's former state telecoms company. Magyar Telekom bought it in 2005, bringing it into the Deutsche Telekom group, and since 2017 its majority owner has been Hrvatski Telekom, the Croatian arm of Deutsche Telekom, which holds about 76.5%. Its separate T-Mobile and T-Com brands were merged into a single "T" brand in 2012, so you may see Telekom branding rather than T-Mobile on shops and in your network list.

The second network this eSIM uses is m:tel CG. A third operator, One, also runs a mobile network in Montenegro but isn't used by this eSIM.

Between Crnogorski Telekom and m:tel your phone has two sets of masts to choose from, and it switches automatically, which helps on a coast where mountains and headlands often block one mast and not another. You'll find 5G in larger towns and busy coastal areas and 4G elsewhere.

Montenegro isn't in the EU, so roaming rules that apply between EU countries don't cover it. Keep data roaming switched off on your home SIM and let the eSIM carry your data.

Registering within 24 hours and the 90-in-180-day rule

Every visitor to Montenegro must be registered with the local tourist office or the police within 24 hours of arriving. Hotels and many holiday lets do this for you, but if you are staying in private accommodation, such as a room rented directly from an owner, you may need to do it yourself. Not registering can lead to a fine, detention or a court appearance. Ask your host on WhatsApp before you arrive whether they will register you, and keep any registration slip they give you, or a photo of it, on your phone.

Visa-free visitors can stay up to 90 days in any 180-day period, and earlier visits within that window count. Montenegro is not in the Schengen area, so days spent here don't count towards your Schengen allowance, and Schengen days don't count here. That makes it a common stop on longer Balkan trips.

Because Montenegro is outside Schengen, make sure border officers stamp your passport on entry and exit. The dated stamp is your evidence of how long you have stayed. Take a photo of each stamp on your phone in case you need to show it later at another border.

Licensed taxis, Podgorica airport and speed limits

Taxis are a common way to get around the coast, but some drivers overcharge visitors. The UK Foreign Office advises using only licensed taxis, which carry a roof sign with the company name and phone number, and agreeing the fare or the price per kilometre before you set off. Taxi apps are a good alternative, as you see the price and driver details in advance.

At Podgorica airport (TGD), use the licensed taxis waiting outside the terminal, or check that a pre-booked driver is allowed to collect passengers there. If you have arranged a transfer, message the driver your flight number before you fly and save their number.

If you hire a car:

Speeding fines can apply from just 10 km/h over the limit.
The drink-drive limit is less than half the limit in England and Wales.
Check the RAC's Montenegro guide for equipment and lighting rules before you collect the car.

Around Budva and Kotor, the Foreign Office's general crime advice applies: watch for pickpockets in old towns and on beaches, use the hotel safe and avoid isolated areas at night.

Hiking Durmitor and the mountains safely

Montenegro's mountains, from Durmitor above Žabljak to Prokletije on the Albanian border, are a major draw, and the Foreign Office reports that hikers have become lost after leaving marked paths. Its advice is practical and mostly phone-related:

Stay on marked trails and take advice from local guides about routes and conditions.
Don't underestimate the weather: storms can arrive quickly in summer, and snow lingers on high ground well into spring.
Carry a charged phone and a power bank, plus water and food.
Tell someone your route and your expected return time before you set off.
Call 112 in an emergency.

Before heading up, download an offline hiking map that shows marked trails, and save the location of your car or accommodation. Signal comes and goes on ridges and in valleys, so if you need to call for help and have no bars, climb to higher open ground.

On the coast, follow lifeguard flags and beach warning signs, take local advice on jellyfish and sea urchins, and watch for speedboats near swimming areas in summer. For adventure activities such as paragliding or jet-skiing, check the operator's licence and insurance first.

7-day itinerary

Seven days in Montenegro: Bay of Kotor, Lovćen, Lake Skadar and Durmitor

A road-trip week for travellers with a hire car who want both coast and mountains: the walled town of Kotor and its bay, the royal capital Cetinje and Lovćen, the Budva Riviera, Lake Skadar, Ostrog Monastery and the lakes and canyons of Durmitor.

Length: 7 days
Bases: 4

When to go May, June and September are warm and less crowded on the coast; the mountain roads to Durmitor are most reliable from June to early October, and snow can close high passes such as the Lovćen road in winter.

Day 1 Kotor

Kotor's old town

Tivat airport is about 15 minutes from Kotor; Podgorica is about 1.5 hours.

Arrive via Tivat or Podgorica airport and drive to Kotor. Walk through the Sea Gate into the walled old town, a UNESCO site, and wander its squares to the Cathedral of St Tryphon and the Maritime Museum. Make sure your accommodation registers you with the police or tourist office within 24 hours. In the evening, walk the waterfront as the walls light up.

Signal Crnogorski Telekom and m:tel CG offer 5G in larger towns, and coverage in Kotor's old town is good, though narrow stone lanes can weaken it indoors.
Day 2 Kotor

Kotor fortress and Perast

Perast is about 20 minutes' drive from Kotor.

Climb the steps up to the Fortress of St John above Kotor early, before the heat, passing the Church of Our Lady of Remedy; allow about 1.5 to 2 hours return. In the afternoon, drive around the bay to Perast, a small Baroque town of captains' palaces. Take a boat to Our Lady of the Rocks, a church on an artificial islet, and look across to St George's island.

Signal 4G holds up the fortress path and along the bay road to Perast; it's also fine on the short boat ride to Our Lady of the Rocks.
Day 3 Kotor

Lovćen and Cetinje

Kotor to the Lovćen mausoleum takes about 1.5 hours on the switchback road; Cetinje is 30 minutes beyond.

Drive the old serpentine road from Kotor up towards Lovćen National Park, with views back over the bay. Climb the 461 steps to the Njegoš Mausoleum on Jezerski vrh for a view over much of the country. Continue to Cetinje, the old royal capital, to see King Nikola's Palace museum and Cetinje Monastery, then return to Kotor.

Signal Coverage is patchy on the upper switchbacks of the Kotor serpentine and in the forest of Lovćen; Cetinje has good 4G.
Day 4 Virpazar

Budva and Sveti Stefan

Kotor to Budva takes about 30 minutes; Sveti Stefan to Virpazar about 1 hour.

Drive down to Budva and walk the small walled old town and the Citadel. Continue south along the coast to the viewpoint above Sveti Stefan, the fortified islet now a private resort, and swim at the public beach nearby. In the late afternoon, take the road inland over the hills to Virpazar on Lake Skadar.

Signal Strong 4G and 5G in Budva; coverage weakens on the hill road between the coast and Virpazar.
Day 5 Žabljak

Lake Skadar and Ostrog Monastery

Virpazar to Ostrog takes about 1.5 hours; Ostrog to Žabljak about 2 to 2.5 hours on mountain roads.

Take an early boat trip from Virpazar into Lake Skadar National Park, the largest lake in the Balkans, to see water lilies, pelicans and island monasteries. Afterwards, drive north to Ostrog Monastery, built into a vertical cliff face and one of the main Orthodox pilgrimage sites in the region; dress modestly. Continue into the mountains to Žabljak.

Signal Signal varies on the lake and fades in the gorges between Nikšić and Žabljak; Žabljak town has 4G.
Day 6 Žabljak

Durmitor National Park

The Đurđevića Tara Bridge is about 30 minutes' drive from Žabljak.

Walk around the Black Lake, about 1 hour, below the peaks of Durmitor National Park. Then drive to the Đurđevića Tara Bridge, which crosses the Tara River canyon about 150 m above the water. Experienced hikers can instead climb towards Bobotov Kuk with a guide; the Foreign Office notes hikers have got lost after leaving marked paths.

Signal Coverage is decent around the Black Lake and Žabljak, but drops on high trails and at the bottom of the Tara canyon; download the route before you go.
Day 7 Podgorica

Drive to Podgorica and depart

Žabljak to Podgorica takes about 2.5 to 3 hours via Kolašin.

Drive south through the Piva or Morača canyons; the Morača route via Kolašin passes Morača Monastery, with thirteenth-century frescoes. In Podgorica, see the Millennium Bridge and the old Ottoman quarter of Stara Varoš if time allows, then return your car at the airport. Make sure your passport is stamped on exit, as Montenegro is outside Schengen.

Signal There are gaps in the Morača canyon and its tunnels, but coverage is good from Kolašin onwards and in Podgorica.

Staying connected on this route

Download offline maps for Lovćen and Durmitor before day 3; mountain switchbacks and canyons have long dead spots.
Use only licensed taxis with roof signs, or apps, and save the company number before late-night trips.
Make sure you're registered within 24 hours of arrival; keep a photo of the registration slip on your phone.
