Internet in Serbia for tourists: staying connected in the Balkans

Internet in Serbia for tourists: why a “Europe” plan doesn’t fully cover the Balkans, which countries MoreSim’s plan includes, and how to set up data for a road trip through four countries.

Internet in Serbia is rarely a problem for tourists: in Belgrade, Novi Sad and Niš the mobile network is strong, Wi-Fi is easy to find in cafes and hotels, and a travel eSIM installs at home and switches on after you cross the border. The trouble starts on a Balkans road trip: Serbia, Montenegro, Bosnia and Herzegovina, Albania and North Macedonia aren’t in the EU, so “Europe” regional plans include them selectively. As of October 2026, MoreSim’s Europe plan covers all of them except Bosnia and Herzegovina, so check the country list against your route before you buy.

Why doesn’t a “Europe” eSIM plan fully cover the Balkans?

A “Europe” plan doesn’t fully cover the Balkans because regional plans are usually built around the European Union and its shared roaming rules, and Serbia, Montenegro, Bosnia and Herzegovina, Albania and North Macedonia aren’t EU members. So in a plan called “Europe”, Balkan countries turn up selectively: one is included, its neighbor isn’t. Every seller has its own set, and there’s little logic in it from a traveler’s point of view.

There’s one reliable rule for the Balkans: read the full country list on the plan card rather than going by the word in its name. With MoreSim, the list of countries is shown in the plan description on the website and in the @moresim_bot Telegram bot. Check it against your route before you buy, including countries you’re just passing through.

You can also skip regional plans entirely and get a local plan for each country. It’s a bit more work while packing, but there’s nothing to cross-check: a local plan for Serbia works in Serbia, full stop. Which option is more convenient depends on how many countries are on your route and how much data you actually use.

What is mobile internet like in Serbia, and where does it drop?

In Belgrade, Novi Sad, Niš and Subotica, mobile data usually works smoothly: maps load, messaging is snappy, video plays. Highways between Serbian cities hold a signal too, since Vojvodina is flat and towers line the roads. Dead zones start farther south and in the mountains: Zlatibor, Tara, and the gorges along the Drina and the Danube around Đerdap. That’s normal network behavior in mountainous terrain, not a problem with any particular plan.

Wi-Fi is common in Serbian cities: cafes, bakeries, hotels, bus stations. Quality varies, so don’t rely on station Wi-Fi before an overnight journey. Save everything you’ll need on the road, such as tickets, bookings and your apartment address, as screenshots in advance so you don’t depend on either mobile data or Wi-Fi.

What is coverage like in Montenegro and on the road through Bosnia?

On the Montenegrin coast, in Budva, Kotor, Tivat and Herceg Novi, the network is usually strong, though slower at peak season because of the load. In Durmitor, on Lovćen and on mountain switchbacks, data drops in patches: you have it between bends and lose it in the shadow of a cliff. It’s the same in the Tara Canyon and on the roads to the northern monasteries.

Bosnia adds terrain of its own. Sarajevo and Mostar have coverage, but the highway between them runs through the Neretva gorge, where the signal jumps around. If you’re driving, download an offline map of the whole country, not a single city: a navigation app with an offline map keeps guiding you without signal. Plan gas stops, cafes and overnight stays along the way while you still have data.

• Belgrade, Novi Sad, Niš: stable network, usually no data problems.
• Zlatibor, Tara, Đerdap: gaps in gorges and on climbs, which is normal in the mountains.
• Montenegrin coast: strong coverage, but the network is busier in summer.
• Durmitor and mountain switchbacks: signal comes and goes with the terrain.
• Sarajevo and Mostar: coverage in town, patchy on the road between them.
• Buses and border crossings: keep everything you need offline.

What happens to your signal at a Balkan border?

At a Balkan border your phone often still clings to the network of the country you’re leaving: data no longer works, but the phone hasn’t switched to the new network. You cross borders often here, and almost always with a stop: a Belgrade to Sarajevo or Belgrade to Budva bus waits at the crossing for anywhere from a few minutes to an hour, and cars can be checked for longer.

Airplane mode fixes it: toggle it on and off a few minutes after crossing. With a regional eSIM that covers both countries, the phone picks up the local network on its own, sometimes after a couple of minutes. If you have several local plans, you’ll need to select the right country’s eSIM for mobile data manually in settings. To avoid confusion on the move, label the lines in advance: “Serbia”, “Montenegro”, “Bosnia”.

Keep your home SIM in the phone for the whole trip. Turn off mobile data on it so your data doesn’t go through your home carrier; otherwise, the moment the local network drops, the phone may switch to roaming on its own. Keep the line itself on if you’re expecting texts from your bank; your carrier needs roaming available for that. Menu names differ between software versions, so look for the section with mobile data and roaming.

SIM card in Serbia or an eSIM for the whole route?

For a route through several countries an eSIM is more convenient, while a local SIM card in Serbia makes sense if you’re staying in one country for a long time. Serbian SIMs are sold at carrier stores and kiosks; since 2025, prepaid numbers in Serbia must be registered, and as a foreigner you’ll need your passport. As of October 2026, a Serbian SIM works on home terms in Montenegro, Bosnia and Herzegovina, Albania, North Macedonia and Kosovo, which have shared a regional “roam like at home” zone since 2021. That zone doesn’t extend to EU countries such as Croatia, Hungary and Bulgaria.

An eSIM is convenient precisely because there’s nothing to physically swap. The profile installs as a second line, and your home number and physical SIM stay in the phone. MoreSim plans are data-only, with no phone number. You can call over messaging apps where they aren’t restricted, and bank texts keep arriving on your home SIM. You can buy on the website or in the bot, paying with Telegram Stars from any country, right in the bot (bank card and SBP payments currently work with cards issued in Russia), and run the bot’s compatibility check in advance, because eSIM support depends on your phone model.

What should you do before your Balkans road trip?

Before a Balkans road trip, match your countries against the plan, install your eSIMs at home and download maps: on the road you’ll have neither the time nor a stable connection.

1. List every country on your route, including transit ones where you’ll spend at least a few hours.
2. Check the list against the countries on the regional plan’s card. If even one is missing, pick another option or go with local plans.
3. Run your phone through the automatic compatibility check in the @moresim_bot bot.
4. Buy and install your eSIMs at home while you have stable Wi-Fi.
5. Download offline maps of all of Serbia, Montenegro and Bosnia, not city by city.
6. On the road, turn on data roaming on the eSIM line and turn off mobile data on your home SIM.
7. If you run out of data early, top up without a new eSIM: use “Top up data” on the eSIM card in your account or in the bot’s app, if top-ups are available for that plan.

If data doesn’t come back after a border, wait a couple of minutes and toggle airplane mode. Still nothing? Check which line is selected for mobile data and whether data roaming is on for it. We’re available via /support in the bot, a ticket in your account and email.
