Internet in Serbia: a pre-trip guide
Internet in Serbia: the Balkans' busiest transit country
Everyone driving to Greece, Bulgaria or Montenegro passes through Serbia, and Belgrade keeps growing as a city-break destination. Serbia is outside the EU, so free EU roaming does not work there and data bills from the first megabyte at non-EU rates. Your operator does not distinguish transit from a stay; you pay the same even if you are just passing through.
How much data for Serbia?
For pure transit with navigation even a small package would do, but 5 GB gives you slack for traffic jams, detours and an evening in Belgrade. For a city break or a longer stay, 10 GB is safer. The package is valid 30 days, so it also covers the return leg on the same route.
How to activate your Serbia eSIM?
After payment the QR code arrives by e-mail. Install the eSIM at home on Wi-Fi; the package activates only on first connection to a Serbian network, which is exactly when you cross the border. Enable data roaming for the eSIM line and navigation keeps guiding without a break, while your own number stays active.
Coverage in Serbia and further down the road
The package works in Serbia on A1 (LTE): Belgrade, Nis, the A1 motorway south and the border crossings. The same wide-coverage eSIM also works in the countries before and after Serbia, including Hungary, Bosnia, Montenegro and Bulgaria, so one package handles the whole route south.
eSIM or a local SIM in Serbia?
For transit, buying a local card makes no sense: you lose time at the border of a country you are only driving through. For a longer stay in Belgrade a local card can be cheap, but it requires passport registration. An eSIM solves both scenarios with one purchase before the trip, at a price known upfront.
eSIM Serbia - FAQ
Does my phone roaming work in Serbia?
Serbia is outside the EU "Roam like at home" zone, so your Polish operator charges extra for roaming there - often several złoty per day or more. An eSIM gives you data without those roaming bills, active the moment you arrive.
Does my phone support eSIM?
eSIM works on iPhones from XS/XR (2018) onward and most newer Androids - Samsung Galaxy S20 and later, Google Pixel 3 and later, and many more. If your phone is from the last few years, it almost certainly works. Quick check: in your mobile network settings look for the option to add an eSIM - if it's there, you're set.
Does the eSIM work across Serbia?
Yes - the plan covers Serbia on local partner networks, data across Serbia and the Balkans. Coverage and speed depend on the local operator.
How do I get and install it?
After payment we e-mail a QR code. Open your phone's eSIM settings, scan it, and the data plan is ready. You keep your usual number.
How long is the plan valid?
The plan is valid for 30 days from first use - from when you connect to a network in your destination, not from purchase. So you can buy and install it in advance; the clock starts on arrival.
Do I keep my number and WhatsApp?
Yes. The eSIM runs on data alongside your usual SIM (dual-SIM), so your number, calls, SMS and WhatsApp on your number keep working normally. The eSIM only adds cheap data.
Can I top up when data runs out?
Yes - when you're close to running out, we send you a top-up link. Same number, no card swap, data is back the moment you pay.
Can I share it as a hotspot?
Yes - most plans allow tethering, so you can share the data with a laptop or a travel companion's phone.
When does it start counting?
Install it before you travel - data starts when you connect to a network in your destination, not before.
What if the eSIM doesn't work?
Write to kontakt@roadence.com or reply to your QR-code e-mail. Usually you just need to turn on data roaming for the eSIM in settings - we'll help you step by step, and if needed we'll issue a new eSIM.
