Serbia is one of the few countries in Europe where the local prepaid counter is not obviously the wrong answer. A1 will sell a visitor a hundred gigabytes for 500 dinars, roughly five dollars, on a short validity window. Yettel puts fifty gigabytes on a card for under a thousand. Nobody in Vienna or Rome is getting anything close to that. What the low price hides is a set of costs that do not appear on the receipt: your passport goes into an operator database because Serbian law says it must, the kiosks in the arrivals hall shut in the early evening, the whole thing stops working the moment you cross into Bosnia or back into Hungary, and the pack you buy is built around call minutes to Serbian numbers you have no reason to dial. This page lays out what the three operators actually charge in dinars this summer, what registration involves, and where the line falls between the counter and a travel eSIM.

Three Operators, Two of Them Renamed Recently
Serbia has three national mobile networks and two of them answer to names that did not exist a few years ago, which is why older forum threads and guidebooks send visitors looking for shops that no longer exist under that sign.
mts is the retail brand of Telekom Srbija, the state-controlled incumbent and the biggest operator in the country. A1 Srbija was Vip mobile from its launch until 2021, when the Austrian A1 Telekom group brought it into the group-wide brand it uses from Vienna to Sofia. Yettel is the strangest name of the three and the newest: it was Telenor Serbia until 2022, when the Czech investment house PPF, having bought Telenor's central European operations, invented a brand to replace the Norwegian one. If a blog tells you to find a Telenor shop on Knez Mihailova, it means Yettel, and the shop is still in the same place.
Which one is best in the shop window
On the ground the differences are narrow and specific. mts carries the incumbent's inherited transmission network, which shows up as better signal in villages, on the Danube road east of Golubac and around the western mountains. A1 is the sharpest performer inside Belgrade and Novi Sad and priced most aggressively for tourists. Yettel sits between them and has the most visible retail presence in the pedestrian centre of Belgrade. For a trip that never leaves the cities, pick on price. For a car trip through the southwest, pick mts.
What Each Operator Charges a Visitor
Prepaid in Serbia works on a starter card plus an add-on package. The card itself is cheap, usually a few hundred dinars with some credit already loaded, and the data comes from a package you activate on top of it. Tourist-labelled bundles come and go with the season, so treat these as the shape of the market rather than a price list carved in stone.
Summer 2026 prices at the counter
A1 Srbija runs the most eye-catching visitor offer, a short-validity internet pack marketed at arriving foreigners with a very large allowance, around 100 GB, for roughly 500 dinars over a few days. Its standard prepaid starter sits near 400 dinars with a gigabyte of open internet plus a separate allowance ring-fenced for WhatsApp, Viber and Messenger. Yettel starter cards begin around 600 dinars, with monthly data packs from roughly 999 dinars for a very large bundle and tourist-oriented offers reaching about 1,399 dinars for thirty days. mts tourist packs generally run between 600 and 1,800 dinars depending on the size of the allowance and how long it lives. At roughly 100 dinars to the dollar, that whole range is between five and eighteen dollars.
Read those numbers twice, because two things are hiding in them. The first is validity. The headline hundred-gigabyte offer expires in days rather than weeks, which is generous if you are streaming in a Belgrade apartment and useless if you wanted a month of light navigation. The second is the voice component. Serbian packs are still sold on unlimited minutes and texts to domestic numbers, and a visitor who arranges everything through WhatsApp and Booking messages will finish the trip with every one of those minutes unused, having paid for them regardless.
The honest summary: per gigabyte, Serbia is cheap. Per useful gigabyte over a two-week trip, the gap between the counter and an eSIM narrows to a few dollars.
Every Serbian Prepaid Line Is Registered to a Person
Serbia does not permit anonymous prepaid numbers. Under the electronic communications legislation the operator must record who a card belongs to before it carries traffic, and for a foreign visitor that means a passport handed across the counter and copied or scanned into the operator's system while you stand there. Some shops photograph the document, some type the details in by hand, and either way the line does not activate until it is done.
How the purchase runs in a Serbian shop
1. Hand over your passport. A national ID card from an EU country is generally not accepted for a foreigner, and a driving licence never is.
2. Say what you need in gigabytes and days. Staff will otherwise sell you the pack with the biggest voice allowance, which is not what you want.
3. Pay in dinars. Cards work in operator shops and malls, though smaller kiosks prefer cash.
4. Wait for the SMS confirming activation, then load a map or a photo-heavy page before you leave. Sorting a dead pack later, in a shop that closes at eight, is the failure mode worth avoiding.
The requirement has two knock-on effects worth knowing before you join the queue. Each traveller has to be present with their own document, so one person cannot walk out with four working cards for the family. And the registration is a permanent record tied to your passport number, which some visitors are relaxed about and others are not. Neither is a scandal, but both are real costs that the 500 dinar price tag does not mention.
A travel eSIM sidesteps the whole procedure. It is sold abroad under the retail rules of wherever you bought it, so there is no Serbian registration to complete, no counter to reach before closing time and no document to surrender in an airport queue.
Serbian Prepaid and Travel eSIMs Side by Side
| Option | What you get | Price | Suits |
|---|---|---|---|
| A1 visitor internet pack | Very large allowance, few days validity | Around 500 RSD | Streaming a long weekend from an apartment |
| A1 standard starter | 1 GB open data plus messaging apps | Around 400 RSD | Someone who mainly wants a Serbian number |
| Yettel monthly pack | Large bundle, 30 days | From about 999 RSD | A month based in Belgrade |
| Yettel tourist offer | Data plus domestic minutes, 30 days | Around 1,399 RSD | Long stays that involve local calls |
| mts tourist pack | Mid-sized data bundle | 600 to 1,800 RSD | Rural driving where mts coverage counts |
| Travel eSIM | 5 GB, 30 days, data only | About $14, near 1,400 RSD | The typical one or two week visit |
| Travel eSIM | 10 GB, 30 days, data only | About $22, near 2,200 RSD | Road trips leaning on live navigation |
| Unlimited eSIM | Unlimited data, 7 days | About $27, near 2,700 RSD | Heavy users and shared hotspots |
Line them up in dinars and the picture is not the one you get in Albania or Croatia. Serbian counter pricing is competitive, and at the largest allowances it flatly wins. What it does not win on is the shape of the product. A 5 GB eSIM month at roughly 1,400 dinars sits almost exactly level with a Yettel monthly pack while requiring no document, no shop and no queue, and it is working before the aircraft doors open. That equivalence is the whole decision.
Where to Buy a SIM Around Serbia
Belgrade Nikola Tesla Airport. All three operators keep staffed stands in the arrivals area past baggage reclaim, and they are the first thing most visitors see. They are also not open around the clock: typical hours run from mid-morning to around eight in the evening on weekdays with shorter weekend cover, which strands anyone on a late Wizz or Air Serbia arrival. The Belgrade Airport guide covers the layout, the WiFi and the routes into town.
Central Belgrade. The operator shops cluster along Knez Mihailova and around Terazije and Trg Republike, within a few minutes of each other, and prices there match the airport exactly. If you are undecided, waiting until your first morning in the city costs nothing and gets you a staff member with time to explain the packs.
Shopping centres. Usce and Galerija on the New Belgrade side of the river, Delta City in Novi Beograd and BEO Shopping Center all carry full-service branches of at least two operators, usually open until nine or ten, which is the fallback when the high street shops have closed.
Topping up once the credit runs down
Recharge vouchers are sold in the trafike, the small green newspaper kiosks on almost every Belgrade street corner, and at petrol stations and supermarket tills nationwide. Ask for a dopuna and name the operator. All three also run apps that take a card, though the app route assumes you still have working data. Outside Belgrade and Novi Sad, keep dinars in your pocket: a village kiosk in the Sumadija is not going to take a contactless tap for a 300 dinar voucher.
What Happens to Your Card at the Border
Serbia sits at the junction of two entirely different roaming worlds, and a card bought in Belgrade behaves differently depending on which way you drive out of it.
Head south or west into Bosnia and Herzegovina, Montenegro, North Macedonia, Albania or Kosovo and you are inside the Western Balkans regional roaming zone, where surcharges between the six were abolished in mid-2021. A Serbian contract line travels into that zone on home terms. Prepaid tourist packs are a greyer area, because operators apply fair-use limits and sometimes exclude promotional bundles from regional use, so ask the question explicitly at the counter rather than assuming.
Head north or east into Hungary, Romania, Bulgaria or Croatia and you are in the EU, where your Serbian card is a foreign SIM roaming at international rates. The reverse trip is the one that catches people out: an EU or UK plan crossing into Serbia loses its home allowance immediately, which is why so many visitors arrive already looking for a fix.
Buy a Serbian card when
Buy a travel eSIM when
If you go the eSIM route, the network your provider rides is worth a glance before the price is. That mapping is listed provider by provider in the Serbia eSIM guide, and it matters far more on the Djerdap gorge road than any few dollars of savings do: the unlimited plans from Holafly are the only ones that ride mts out there. The eSIM Finder will size the plan if you are unsure how much data a Serbian fortnight consumes.
Frequently Asked Questions
Is a Serbian SIM card actually cheap compared with the rest of Europe?
Yes, measured purely in dinars per gigabyte it is among the cheapest anywhere on the continent. A1 markets a visitor internet pack with an enormous allowance for around 500 dinars, and Yettel puts a very large monthly bundle on the shelf from about 999 dinars. The qualifier is that the biggest allowances come with the shortest validity, and that a large share of what you pay for is domestic call minutes a visitor never dials. Compared like for like against a 5 GB travel eSIM over a month, the gap shrinks to a few dollars.
Can someone else buy a Serbian SIM on my behalf?
Not properly, no. The line has to be registered against an identity document before it will carry traffic, and the document has to be yours. In practice that means every member of a travelling group queues individually with their own passport, and a friend already in Belgrade cannot have a working card waiting for you at the apartment. It is one of the quieter reasons families end up on eSIMs, since installing four profiles at home takes about the same time as one person reaching the front of the queue at the airport.
Which Serbian network should I choose for driving in the mountains?
mts. Telekom Srbija inherited the old state transmission network, and that legacy is exactly what fills in the gaps on the roads through the Djerdap gorge, around Zlatibor and Tara, and out toward Uvac. A1 and Yettel are both excellent in Belgrade, Novi Sad and Nis and along the motorway, but they thin out sooner once the road starts climbing. If you are on a travel eSIM instead, note that only unlimited plans from Holafly reach mts in Serbia.
Where do I add more credit once I am outside Belgrade?
The trafika, the small kiosk selling newspapers, cigarettes and bus snacks that stands on virtually every corner in every Serbian town. Ask for a dopuna, name your operator, and pay in cash. Petrol stations and supermarket checkouts sell the same vouchers. Each operator also has an app that accepts a bank card, though that only helps if you still have enough data left to open it, which is a circular problem worth avoiding by topping up early.
Will the card still work if I take the bus from Belgrade to Sarajevo?
For a regular contract line, yes: the six Western Balkans countries scrapped roaming surcharges among themselves in 2021, so a Serbian number behaves normally in Bosnia. For a cheap tourist data pack the answer is less certain, because operators attach fair-use conditions and often exclude promotional bundles from regional roaming. Ask at the counter before you rely on it, and if the itinerary is genuinely multi-country, a Balkans regional eSIM removes the guesswork.
