Quick answer: Serbia isn't in the EU, so your Europe eSIM won't work here — buy a Serbia-specific or Balkans regional plan before you fly. OVOSIM connects to A1 with 5G/4G LTE from €3.50, no KYC required, and setup takes about three minutes.
The one thing to get right before you fly
Serbia is not an EU member. If you've bought a standard "Europe" eSIM for a wider trip, it will not work once you cross into Serbia — this is the single most common mistake travelers make here. Buy a Serbia-specific plan or a Balkans regional plan that explicitly lists Serbia.
Setting it up
- Buy your eSIM online before you fly — you need internet to install it, so do this at home or on airport Wi-Fi, not after landing.
- Scan the QR code: Settings → Cellular → Add eSIM.
- Label it "Travel Data" and set it as your secondary line, so your home number stays active for calls and WhatsApp.
- Leave it switched off until you land.
- On arrival, turn on the Serbia eSIM line and enable Data Roaming for that line only.
No KYC or document upload is required for the Serbia eSIM — it activates straight off the QR code.
What to budget for data
Belgrade and Novi Sad are light on data if you're mostly using maps, messaging, and social apps — a few days of a 1-3GB plan comfortably covers a city weekend. If you're hotspotting a laptop or working remotely from a café, budget for 5-10GB. Streaming video regularly pushes you toward the higher tiers or an unlimited plan.
Currency and everyday practicalities
Serbia uses the Dinar (RSD), not the Euro — worth having a currency converter app ready even though most tourist-facing prices are also shown in Euros. Bolt operates in Belgrade for ride-hailing; Uber's presence in Serbia is limited compared to Bolt.
If you're continuing into other Balkans countries
Serbia shares a regional roaming zone with Albania, Montenegro, Kosovo, North Macedonia, and Bosnia and Herzegovina for local physical SIMs — but that agreement doesn't automatically extend to international eSIMs. If your trip crosses into any of those countries, a Balkans regional eSIM that explicitly lists each country avoids buying a new SIM at every border. See our full Balkans eSIM guide for border-crossing tips and country-by-country coverage, or jump straight to Albania, Kosovo, and Montenegro.
