Skip the SIM-card queues and roaming fees. Here's how a Serbia eSIM gets you online the moment you land, with fast 4G/5G across the country.
Touch down in Belgrade and your phone is already online — no kiosk hunt, no passport photocopies, no surprise roaming bill. That's the beauty of a Serbia eSIM.
Why use an eSIM in Serbia
A Serbia eSIM is a digital SIM you install before you fly. You keep your regular number for calls and WhatsApp, and add a local data plan that activates the second you arrive. No plastic to swap, nothing to lose, and prices that beat carrier roaming by a wide margin.
Serbia has three strong mobile networks: MTS (Telekom Srbija), A1, and Yettel. All three run nationwide 4G/LTE, and 5G is expanding fast in Belgrade, Novi Sad, and Niš. Coverage is excellent in cities and along major highways, and dependable through Šumadija, Vojvodina, and the south.
How to get connected
1. Buy your Serbia eSIM online and check your email for the QR code.
2. Scan the QR in your phone's settings (Cellular / Mobile Data — Add eSIM).
3. Switch on data roaming for the eSIM line when you land, and you're connected.
How much data do you need
Light (maps, chat, email): 1–3 GB for a short city break
Average (social, browsing, some streaming): 5–10 GB for a week
Heavy (video, hotspot, remote work): 15–20 GB or more
If you lean on Google Maps and post a lot, size up — it's cheaper than topping up twice.
Don't miss: Belgrade Fortress (Kalemegdan), Novi Sad's Petrovaradin Fortress, and the dramatic Đerdap (Iron Gates) gorge on the Danube
FAQ
Will my phone work with an eSIM?
Most phones from the last few years support eSIM — iPhone XS and newer, Google Pixel 3 and up, and recent Samsung Galaxy S/Note/Z models. Check Settings for an "Add eSIM" option, and make sure your phone is carrier-unlocked.
When should I install it?
Install before you travel while you have Wi-Fi, but choose a plan that starts on arrival. The data activates once you connect to a Serbian network, so you won't waste days.
Can I keep my WhatsApp number?
Yes. WhatsApp is tied to your original phone number, not the eSIM. Your number and chats stay exactly the same — the eSIM only carries data.

When should I activate my Serbia eSIM?
Most HelloSIM plans start their validity when the eSIM first connects to a network, so activate on arrival in Serbia. Confirm your specific plan's terms, as a few begin on installation.
Which networks does HelloSIM use in Serbia?
HelloSIM connects to major Serbian carriers such as MTS (Telekom Srbija), Yettel, and A1 Serbia, automatically picking the strongest available signal for reliable coverage.
Is there 4G in Serbia?
Yes, 4G LTE covers Belgrade, Novi Sad, Niš, and most of the country, and it's the standard connection you'll use for browsing, maps, and video calls.
Is 5G available in Serbia?
5G is rolling out in Belgrade, Novi Sad, and other larger cities, though coverage is still expanding. If your phone and plan support it you may see 5G, otherwise fast 4G is the norm.
How good is coverage across Serbia?
Coverage is excellent in cities and along highways, and generally solid in smaller towns and rural areas. Signal can weaken in remote mountainous regions and deep valleys.
How much data do I need for a week in Serbia?
Around 3-5 GB comfortably covers a week of maps, messaging, and social media for most travelers. Choose more if you stream a lot of video or tether other devices.
How much does a Serbia eSIM cost?
Prices depend on data volume and validity, but short travel plans typically fall in the low single-digit to low double-digit euro range. Check HelloSIM for current Serbia pricing.
How long are Serbia eSIM plans valid?
Validity varies by plan, commonly from a few days up to 30 days. Pick a window that comfortably covers the length of your visit.
Can I use my phone as a hotspot in Serbia?
Yes, HelloSIM data supports tethering, so you can share your connection with a laptop or tablet. Hotspot usage counts against your plan's data allowance.
Can I keep my home number active in Serbia?
Yes. Your primary SIM or eSIM stays on for calls and texts on your home number, while the HelloSIM eSIM handles data. This dual-SIM approach is perfect for travel.
Will I still get my regular calls and texts?
Yes, if you keep your home line switched on for voice. Turn off data roaming on that line to avoid charges, and let the HelloSIM eSIM handle all your internet.
Do I need to configure an APN in Serbia?
Usually not, as HelloSIM eSIMs set the APN automatically. If data doesn't work, check your plan's instructions and enter the provided APN in your mobile data settings.
Do I have to turn on data roaming?
Yes. Since the eSIM uses a local partner network, enable data roaming for that eSIM line. This causes no extra charges because your data is prepaid through HelloSIM.
Does the Serbia eSIM include phone calls and SMS?
HelloSIM Serbia plans are generally data-only. You can call and message over the internet using apps like WhatsApp, Viber, FaceTime, or Signal, which are widely used in Serbia.
Can I make normal calls with the Serbia eSIM?
The eSIM provides data rather than a local phone number, so use VoIP apps such as WhatsApp or Viber for calls. Viber in particular is very popular across Serbia.
What happens when I run out of data?
You can buy another HelloSIM plan or add-on to keep going, without switching eSIMs. It's smart to top up before you fully run out if you rely on constant connectivity.
How do I top up my Serbia eSIM?
Sign in to your HelloSIM account or app, select a top-up or new Serbia plan, and it applies to your existing eSIM. If your data has run out, do this over Wi-Fi.
Can I use the Serbia eSIM in nearby countries?
A Serbia-only plan works within Serbia. If you're also visiting Montenegro, Bosnia, North Macedonia, or the wider Balkans, consider a HelloSIM regional or Europe plan instead.
Does a Europe eSIM plan cover Serbia?
Not all Europe plans include Serbia, since it's not an EU member. Check the coverage list before buying, or choose a HelloSIM plan that specifically lists Serbia.
Will I have internet at Belgrade airport when I land?
Yes, if your eSIM is installed and data roaming is enabled, it should connect shortly after you land at Belgrade Nikola Tesla Airport. Turn it on before leaving the plane for a faster start.
How do I get online right after landing in Serbia?
Install the eSIM and set it as your data line before your flight. On arrival, switch on data roaming for the HelloSIM line and it should register on a Serbian network within a minute or two.
What download speeds can I expect in Serbia?
On 4G in cities like Belgrade and Novi Sad you can generally expect speeds fine for HD streaming, video calls, and fast browsing. 5G, where available, is faster still.
What is the emergency number in Serbia?
Serbia uses 112 as the general emergency number. You can also dial 192 for police, 193 for the fire service, and 194 for an ambulance. These work without an active data plan.
My Serbia eSIM shows no service, what should I do?
Check that data roaming is on for the eSIM line, toggle Airplane Mode on and off, and try manually selecting a network like MTS or Yettel. A restart usually resolves registration problems.
The eSIM won't register on a network in Serbia, how do I fix it?
Give it a few minutes after landing, then manually select a Serbian carrier in your network settings. Make sure the HelloSIM line is enabled and set as your data source, and reboot if needed.
Can I use the eSIM for Google Maps in Serbia?
Yes, the data works smoothly with Google Maps and navigation apps. Downloading offline maps ahead of time is handy for rural drives or spots with weaker signal.
Should I download offline maps before visiting Serbia?
It's a good idea. Saving offline maps of Belgrade and any regions you'll explore ensures you can navigate even in areas with limited mobile coverage.
Can I install the Serbia eSIM on more than one phone?
No. Each eSIM QR code is valid for a single device. If you need data on a second phone, buy another plan or share your connection via hotspot.
What happens to the eSIM after my plan expires?
When the validity ends or the data is used up, the eSIM stops working but stays saved on your phone. You can top it up to reactivate it or remove it in settings.
Can I get a refund on a Serbia eSIM?
Refunds generally apply to eSIMs that haven't been installed or activated. Review HelloSIM's refund policy and contact support if you hit a problem before activating.
