SIM Cards
Staying connected in Serbia is simple and affordable in 2025. This guide compares the six best SIM card providers in Serbia, including mts, A1, Yettel, Wraptel, travSIM, and Airport Telecom, plus eSIM options from Holafly, Airalo, and Nomad. With mts offering the strongest local coverage and Holafly standing out for unlimited data, you can choose the best SIM or eSIM for fast, reliable mobile data as soon as you arrive.
With 90% of Serbians online and mobile subscriptions exceeding 124% of the population (DataReportal 2024), staying connected here is effortless. Whether you’re streaming in a Belgrade café, hiking near Tara National Park, you’ll find fast and reliable coverage almost everywhere.
In this guide, we compare the six best SIM and three eSIM options for 2025, from local carriers like mts, A1, and Yettel, perfect for longer stays and local calls, to travel-ready eSIMs such as Holafly, which stands out for its unlimited data and instant activation.
1. You’ll save real money. Roaming charges from foreign carriers can get ridiculous. A local Serbian SIM gives you tons of data for just a few euros, and you can top it up anytime at a kiosk or even online.
2. You’ll actually get signal everywhere. Serbia’s main providers, mts, A1, and Yettel, have strong 4G and growing 5G coverage, even in smaller towns or countryside spots. Perfect if you’re exploring places like Novi Sad, Niš, or hiking near Tara National Park.
3. Wi-Fi isn’t always reliable. Sure, there’s Wi-Fi in cafés and hotels, but it’s often slow, shared, or password-locked. With your own SIM, you’ll always have fast, private data for maps, translation, or calling an airport taxi when your flight lands.
4. Local apps just work better. Some Serbian apps and services (like ride-hailing or food delivery) are easier to use when you have a local number. It helps with SMS verifications and delivery calls.
5. You’ll thank yourself the moment you land. Airport Wi-Fi can be spotty, and SIM shops sometimes close early. If you’ve already set up an eSIM, your phone connects the second the plane touches down.
If you prefer a physical SIM card, prices start around $6–7 for short-term visitor plans. For example, you can get an mts Tourist SIM with 75 GB of 4G/5G data valid for 5 days for about $6.50, or a Yettel Prepaid pack with 5 GB and call credit for roughly $4.50.
Longer-term options, like A1’s Super Tourist SIM, give you up to 200 GB and local call minutes for about $19, perfect for a full month in Serbia.
If you prefer to set up your connection before landing, eSIMs offer instant activation and great value too. For instance, Holafly’s Serbia eSIM starts at $7.90 for 1 day with unlimited data, while Airalo and Nomad provide flexible prepaid data from $4–5 for 1 GB (lasting up to a week).
In short,
For instant data when you land, order an eSIM before your trip. You’ll connect automatically as soon as you arrive in Serbia.
