About this eSIM

Serbia is a country where the data works better than travellers expect and the plan coverage catches them out instead. The networks in the cities and along the highway spine are solid; the problem is that Serbia is not in the EU, so a European plan bought for a Balkans trip may simply not include it. Sort that out before you leave and the rest of the country is easy: Belgrade, Novi Sad and the main corridors keep you online without effort.

Getting online when you land

Install the profile before departure, over your home wifi. Nikola Tesla airport is a short drive from central Belgrade and the bus and taxi options are both simpler when your phone can already show you where you are going and what the ride should cost.

On landing, exit airplane mode and give the phone a minute to register. If it finds a network but no data moves, look at the roaming toggle for the travel line first, then at which line is selected for data on a dual line handset. Those account for the overwhelming majority of eSIM problems anywhere.

Leave your home number active for calls and one time codes, with its data disabled so it cannot connect in the background.

The networks you'll be on

Roaming here uses VIP, which runs 4G LTE and 5G where it has been rolled out. 4G is what you will mostly see, and it is entirely sufficient for maps, messaging, streaming music and video calls.

If your connection is poor somewhere it should not be, cycle airplane mode to force a fresh search before you assume anything is wrong.

Where coverage holds, and where it thins

Belgrade is comprehensively covered, including the riverside, Zemun, New Belgrade and the fortress. Novi Sad, Nis, Subotica, Kragujevac and Cacak are all straightforward. The main highway running the length of the country, the route north to the Hungarian border and the roads through Vojvodina keep you connected almost continuously, and the flat northern plain is naturally kind to radio.

Southern and western Serbia are the interesting part. The terrain turns into folded hills and deep river gorges, and coverage follows the roads and the towns rather than the landscape as a whole. Expect drops in the Uvac canyon, along the Drina, through the Iron Gates gorge on the Danube, and in the Tara and Kopaonik national parks once you leave the resort areas for the forest. Mountain villages usually have something; the trails between them often do not. The Sargan Eight railway winds through tunnels where the signal stops and starts. Studenica, Sopocani and the other monasteries tucked into valleys can be quiet spots for data as well as for everything else.

Long distance buses, which are how most people move around Serbia, hold a connection well on the highways and lose it on the mountain sections.

What you'll actually use data for here

Transport planning takes the lead. Serbia's intercity network is mostly buses, timetables change, and checking departures online beats trusting a printed board at a station. In Belgrade the city transport apps and ride hailing both matter, and parking in the central zones is handled by phone.

Then the social layer, because Belgrade is a city people come to for nightlife and the good places are not always the visible ones. Reservations, event listings and the floating clubs on the rivers all live online. Festival goers heading to Petrovaradin fortress for EXIT or to Guca will find their entire logistics happening in chat groups.

The everyday rest: translation between Cyrillic and Latin script, which Serbia uses in parallel and which trips up visitors constantly, card payments and banking apps, live maps for the drive south when the highway signage thins out, and photo uploads from wherever the Danube and the Sava happen to look good.

Before you fly

Check the covered country list on your plan before anything else. This is the Serbia specific step: neighbouring Croatia, Hungary, Romania and Bulgaria sit inside EU arrangements that Serbia does not, and a Balkans road trip crossing several borders needs a plan that names each country you enter.

After that, the usual: confirm your handset is unlocked and eSIM capable, install the profile at home, label it clearly, and download offline maps covering the mountain and gorge sections of your route. Save monastery locations and trailheads as offline pins rather than relying on a search that needs signal.

Size your data around the way you travel. City weekends are light; a driving loop through the south with constant navigation running is heavier than most people estimate.

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 Serbia?

Yes. Your Serbia 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 VIP. 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 Serbia?

Yes, where it has been deployed. 5G runs on VIP in Serbia, 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 Serbia?

Yes. Foreign visitors must be registered with the local police within 24 hours of arrival. The US State Department says hotels usually do this for you, but if you stay in a private home you must register in person at the nearest police station. Ask your host before you arrive, and keep a copy of the registration.

Can I travel from Kosovo to Serbia?

Only if you entered Serbia first through another recognised crossing, for example by flying into Belgrade. Serbia doesn't recognise Kosovo's government, so if you start your trip in Kosovo you'll need to leave through Montenegro or North Macedonia and then enter Serbia. Check this before buying bus tickets.

Are there protests in Belgrade right now?

Anti-corruption protests began after the Novi Sad station canopy collapsed in November 2024, killing 16 people, and were still continuing in 2026. Large rallies have been held in Belgrade. The US State Department says demonstrations can turn violent and cause traffic delays, so check local news and avoid crowds.

What are the emergency numbers in Serbia?

The US State Department lists 192 for police, 194 for ambulance, 193 for fire and 987 for roadside assistance. Your eSIM is data only, so use your home SIM or a local phone to call them. Save the numbers before you set off on long drives through southern and western Serbia.

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

For 7 days in Serbia, Viasimo sells 100 MB for $1.29, 500 MB for $1.29, 1 GB for $2.00, and unlimited data for $14.99. 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

Serbia: what to know before you land

In Serbia your eSIM connects to VIP on 4G and 5G. Before you travel, check three local rules: foreign visitors must be registered with the police within 24 hours of arrival, Serbia won't let you enter directly from Kosovo, and large anti-corruption protests have continued in Belgrade and Novi Sad since late 2024. Mobile data makes it easier to follow all three.

Emergency: 192 police
194 ambulance
193 fire
Plugs: CF 230V
Currency: Serbian dinar (RSD)

Registering with the police within 24 hours

Serbia expects foreign visitors to be registered with the local police within 24 hours of arriving. According to the US State Department, hotels usually do this for you when you check in. If you're staying in a private home, including many apartments booked online, you have to register in person at the nearest police station.

This catches out people who arrive late at night or move between Belgrade, Novi Sad and Niš. A few practical steps help:

Message your host before you arrive and ask whether they'll complete the registration or whether you need to go to the police station yourself.
Have your passport ready, as the registration is linked to it.
Keep a photo of any registration slip or confirmation on your phone, as well as the paper copy, in case you're asked for it later, including when you leave the country.

If you change accommodation, check whether you need to register again at the new address. Use a translation app if the station staff don't speak English, and save the address of the nearest police station in your offline map before you go.

Crossing between Kosovo and Serbia

Serbia doesn't recognise Kosovo's government, and that affects how you can travel between them. The US State Department says Serbian border officials won't admit travellers who enter Serbia from Kosovo unless they first entered Serbia through another recognised crossing.

In practice:

If you fly into Belgrade, travel to Kosovo and then return to Serbia, you can usually re-enter from Kosovo.
If you start your trip in Kosovo, for example by flying to Pristina or coming overland from Albania, you can't cross directly into Serbia. You'll need to leave Kosovo through Montenegro or North Macedonia and enter Serbia from there.

This matters if you're planning a Balkans road trip or bus route. Check bus routes and border options on your phone before you buy tickets, and don't assume a cheaper direct bus from Pristina to Belgrade will let you through.

Your Serbia plan covers Serbia only. Kosovo, Montenegro and North Macedonia use different networks, so download maps and booking details for each leg before you leave Serbian coverage.

Protests since the Novi Sad station canopy collapse

On 1 November 2024, the canopy at the newly renovated Novi Sad railway station collapsed, killing 16 people. Protesters blamed corruption in the renovation, and the demonstrations that followed spread to around 400 towns and cities by March 2025. Belgrade saw rallies of about 325,000 people in March 2025 and around 180,000 to 190,000 in May 2026, and the movement was still continuing in 2026.

The US State Department says demonstrations happen frequently, can turn violent, and bring heavy police presence and traffic delays. For visitors, that mainly means planning around them:

Check local news on your phone on the day, especially for central Belgrade and Novi Sad.
Avoid protest areas and large crowds, and allow extra time for airport transfers and buses.
Use navigation apps with live traffic to find a way around road closures.

On arrival at Belgrade Nikola Tesla Airport (BEG), be careful with taxis, as the State Department warns that some drivers overcharge foreigners. Make sure the meter is running or agree the price first. Save the emergency numbers: 192 for police, 194 for ambulance, 193 for fire and 987 for roadside assistance.

7-day itinerary

Seven days in Serbia: Belgrade, Novi Sad, the Iron Gates and Niš

A road-trip week by hire car for travellers curious about Serbia beyond the capital: two days in Belgrade, Novi Sad and Sremski Karlovci in Vojvodina, the Danube fortresses and Iron Gates gorge, Roman Felix Romuliana and a final day in Niš.

Length: 7 days
Bases: 4

When to go May, June and September offer warm days for the Danube and fortress walks without the 35°C heat of July and August; winters are cold and grey, with shorter opening hours at rural sites.

Day 1 Belgrade

Belgrade: Kalemegdan and the old centre

Belgrade Nikola Tesla Airport is about 30 minutes by taxi or bus from the centre. Make sure your host or hotel registers you with the police within 24 hours.

Walk from Republic Square along the pedestrian Knez Mihailova street to Kalemegdan Park and the Belgrade Fortress, where the Sava meets the Danube. Explore the ramparts, the Victor monument and the old Ottoman gates, then wander down through Kosančićev Venac to Skadarlija, the cobbled bohemian quarter. Check the news before heading into the centre, as large protests have been frequent since late 2024.

Signal Your eSIM connects to VIP, with 5G across central Belgrade. Signal can slow sharply in large crowds and near rallies.
Day 2 Belgrade

Belgrade: St Sava, Tesla and Zemun

City buses and taxis link the sights; Zemun is about 30 minutes on foot along the river from New Belgrade.

Start at the Church of Saint Sava on the Vračar plateau, one of the largest Orthodox churches in the world, with a mosaic-covered interior. Visit the Nikola Tesla Museum, then the Museum of Yugoslavia and the House of Flowers, Tito's mausoleum. In the late afternoon walk along the Danube to Zemun, climb to the Gardoš Tower for views over the rivers, and eat by the waterfront.

Signal Strong 5G throughout the city. Book Tesla Museum tours online in advance, as group sizes are limited.
Day 3 Novi Sad

Novi Sad and Sremski Karlovci

About 35 minutes by Soko high-speed train from Belgrade; Sremski Karlovci is 15 minutes from Novi Sad.

Take the high-speed train to Novi Sad. Cross the Danube to the Petrovaradin Fortress, walk its ramparts and see the clock tower with its reversed hands. Back in town, stroll Zmaj Jovina street to Liberty Square and the Name of Mary Church. In the afternoon take a short trip to Sremski Karlovci for its baroque square and Orthodox cathedral, then drive into the Fruška Gora hills to visit one of its monasteries.

Signal Good 5G in Novi Sad; coverage is patchier on Fruška Gora's forest roads. Protests have also been frequent in Novi Sad, so check local news.
Day 4 Donji Milanovac

Smederevo and Golubac fortresses

About 1 hour 45 minutes from Novi Sad to Smederevo, then around 1 hour 30 minutes to Golubac and 1 hour to Donji Milanovac.

Pick up a hire car and drive east along the Danube. Stop at Smederevo Fortress, a vast 15th-century stronghold on the riverbank, then continue to Golubac Fortress, whose towers climb the cliffs at the entrance to the Iron Gates gorge. Drive on through Đerdap National Park along the river to Donji Milanovac for the night.

Signal Along the Danube your phone may connect to a Romanian network across the river; check it stays on VIP. Coverage is patchy in the narrowest parts of the gorge.
Day 5 Niš

Lepenski Vir and Felix Romuliana

About 30 minutes from Donji Milanovac to Lepenski Vir; around 2 hours to Gamzigrad and a further 1 hour 30 minutes to Niš.

Visit Lepenski Vir, a Mesolithic settlement on the Danube with trapezoid house plans and carved stone heads, displayed under a protective roof. Climb to the Veliki Štrbac viewpoint above the gorge if you have time. Then drive south to Gamzigrad-Romuliana near Zaječar, the late Roman palace built by Emperor Galerius, with mosaics and mausoleums, before continuing to Niš.

Signal Signal is weak in the Đerdap gorge and on the rural roads to Zaječar. Download offline maps for the whole day before leaving Donji Milanovac.
Day 6 Niš

Niš

Explore Niš, Serbia's third city and the birthplace of Constantine the Great. Walk through the Niš Fortress by the Nišava river, then visit the Skull Tower, built by Ottoman forces with the skulls of Serbian rebels after the 1809 Battle of Čegar. See the remains of Mediana, a Roman imperial villa on the edge of town, and spend the evening in the cafés of Kazandžijsko Sokače.

Signal Strong 4G and 5G in central Niš. Don't plan a side trip south into Kosovo: border rules for re-entering Serbia from Kosovo are complicated.
Day 7 Belgrade

Back to Belgrade

About 2 hours 30 minutes by car or 3 hours by bus from Niš to Belgrade.

Drive back north on the motorway to Belgrade, or fly from Niš Constantine the Great Airport if you have a direct flight home. In Belgrade, if time allows, spend a last hour at the Nikola Pašić Square and the National Museum on Republic Square, home to Serbian and European art and archaeology.

Signal Good 4G along the motorway with 5G in Belgrade. Check flight details and return your hire car with directions saved.

Staying connected on this route

Along the Danube in Đerdap, watch for your phone switching to a Romanian network; set network selection to VIP manually if needed.
Check local news daily in Belgrade and Novi Sad for protest routes and traffic disruption.
Download offline maps of eastern Serbia before the Danube and Zaječar drive.
Keep a photo of your police registration slip, in case you're asked for it later.
