eSIM Serbia
Serbia eSIM on the Yettel Serbia network: 1 to 10 GB prepaid, no contract and no registration – you are online within minutes of landing at Belgrade Nikola Tesla airport.
Your Selection
Your plan only starts counting when the eSIM first connects at your destination — so you can buy today and travel in three weeks.
How does Simbye eSIM work for Serbia?
Get connected in under 2 minutes
Choose a plan and pay
Pick the data bundle that matches the length of your trip. The email with a one-click link and a QR code arrives right after payment.
Set it up at home, arrive in Serbia
Install the eSIM calmly before departure, on Wi-Fi. It stays dormant until you are in the country – whether you land in Belgrade at Nikola Tesla (BEG), in Niš at Constantine the Great (INI) or in Kraljevo at Morava (KVO), cross by bus at Horgoš or Batrovci, or come in by train from Budapest.
Turn on data roaming
Once you arrive, switch on data roaming for the Simbye line. Your phone registers on a Serbian network, and only with that first connection does your plan's validity start counting.
Check Device Compatibility
Make sure your device supports eSIM before purchasing
Which networks will you be on in Serbia?
In Serbia the eSIM registers on Yettel Serbia automatically – there is nothing to select by hand.
Half of all mobile speed tests in the country come out above this, half below. Speedtest Global Index, July 2026. There are no separate figures per network for this country.
You do not pick a network. Once you switch on data roaming for the Simbye line in Serbia, your phone registers on Yettel Serbia by itself. If nothing happens after you land, toggle airplane mode off and on and check that network selection is set to automatic. There is no APN to type in.
4G is widely available in Serbia – in Belgrade, Novi Sad, Niš, Kragujevac, Subotica and Užice, and along the motorway that runs from the Hungarian border at Horgoš through Belgrade and Niš down to Preševo. 5G only went live at the end of 2025 and is still being built out, so plan on 4G. In narrow valleys and gorges the signal drops out in patches – at the Uvac, in the Đerdap gorge on the Danube, along the Drina below Tara. That is terrain, and it affects every network in the country the same way.
eSIM or a local SIM card in Serbia?
Skip the shop in Serbia: the eSIM is scanned in before departure and joins Yettel by itself, while a local card means your passport at the counter and dinars in cash on the spot.
| Compared | Simbye eSIM | Local SIM card |
|---|---|---|
| ID and registration | Not required, you buy online | Operator shops normally ask for your passport |
| When you have it | Set up by QR code before departure | Only after you arrive, at a kiosk or shop |
| Network | Yettel Serbia, registers automatically | Whichever network the shop you walk into sells |
| Payment | Online with your own card, in your currency | In dinars on the spot, often in cash |
| Your own number | Stays active, WhatsApp and Viber keep working | A second number, and your phone must run two SIMs at once |
| Serbian phone number | No, data only, no calls or texts | Yes, with a Serbian number, calls and texts |
| Topping up | Online at any time, no shop to find | Credit at a kiosk or in the operator's app |
| If something goes wrong | Email support, in English or German | Back to the counter, usually in Serbian only |
Why roaming on your home contract gets expensive in Serbia
At the Serbian border your bundled home allowance stops counting and your operator's international tariff takes over. In many contracts Serbia is a separate zone billed per megabyte or through day passes – what applies to you is written in your tariff under Serbia. If you do not look it up, you find out when the bill arrives.
Prepaid turns that around: you decide on the data up front, 1 to 10 GB with 7 to 30 days of validity, no contract, no registration and nothing billed afterwards. The eSIM arrives as a QR code, you install it at home on Wi-Fi and it goes live in Serbia.
There is also this: Serbia is a transit country. Drive towards Bulgaria, Greece or Turkey and you may only be in the country for two days – but you need navigation, fuel stops and toll information for every hour of them. Check before you leave what a day pass from your own operator costs for those two days.
How far the network reaches
The eSIM runs on Yettel Serbia, and 4G is in use across the whole country. Belgrade, Novi Sad, Niš, Kragujevac, Subotica and Užice are covered, as is the motorway that runs from Horgoš on the Hungarian border through Belgrade and Niš down to Preševo – exactly the route most people driving through the country take. 5G only arrived at the end of 2025 and is still being built out, so plan on 4G.
Holiday regions are well served, though not evenly: on Zlatibor and in Vrnjačka Banja, on Kopaonik and in the villages of the Fruška Gora you will normally have signal. It thins out where the landscape gets steep – in the Uvac canyon, in the Đerdap gorge on the Danube, along the Drina below Tara and on hiking trails away from the villages. If that is where you are heading, download the map for the day offline beforehand.
In the cities themselves: Belgrade and Novi Sad have dense coverage, but the signal can still drop in the lower floors of shopping centres, in underground car parks and in the underpass at the main station. That is normal and does not mean anything is wrong with the eSIM.
Prepaid without ID – but without a Serbian number
In the operators' shops you are normally asked for your passport when you buy a prepaid SIM, and first you have to find the counter. This eSIM you buy online, with no registration, and set up at home on Wi-Fi with a QR code.
What it does not have is a Serbian number: paying for parking by texting 9111, 9112 or 9113, and any local SMS confirmation, will not work – use the Parking Servis app for parking, and set up accounts like CarGo or Viber while you can still receive texts at home.
