The best eSIM for Serbia.
A hand-written buyer's guide from our editors — what to buy, what to skip, and the network reality on the ground in Serbia. Not a price scraper; a travel read.
For most trips: a 7–10 GB regional plan beats a single-country plan.
Single-country eSIMs often look cheaper per-GB on a spec sheet, but regional plans (for example, a multi-country Europe plan covering Serbia) almost always win on flexibility, carrier choice, and what happens if your flight gets re-routed. If you're staying in Serbia for more than 10 days or doing heavy work, a single-country 20 GB plan is still worth it.
Network reality
Who you'll actually connect to
MTS (Telekom Srbija), A1 Serbia and Yettel cover the country, with strong 4G nationwide and 5G in Belgrade and Novi Sad. Serbia has invested heavily in mobile infrastructure and coverage along the main corridors and in the Vojvodina plain is consistently good.
On the ground
Where coverage gets tricky
Serbia is mostly a city and road-trip destination — Belgrade, Novi Sad, Niš, plus the monasteries and the Đerdap gorge along the Danube. That means steady, moderate data use rather than heavy bursts. Belgrade in particular has abundant café wifi, so a modest plan goes a long way.
Watch out for
The gotcha most travelers miss
Serbia is not in the EU, so EU roaming does not apply and many Europe bundles exclude it. Serbia does participate in the Western Balkans roaming arrangement with Bosnia, Montenegro, North Macedonia, Albania and Kosovo — but that agreement covers local SIMs from those countries, not travel eSIMs bought abroad. Your plan's own coverage list is what governs.

What to buy for Serbia
Three to five gigabytes covers a week comfortably given how much café wifi Belgrade has. As with the rest of the region, the regional-versus-single-country question matters more than the size: if you are crossing into Bosnia, Montenegro or North Macedonia, a Balkans bundle is almost certainly cheaper than stacking plans.
Start with trip length. For a 3–5 day trip, a 3 GB plan is plenty if you're mostly on hotel or cafe Wi-Fi. For 7–14 days of real use — maps, rideshare, translation, messaging — aim for 7–10 GB and don't overbuy; unused data expires on most plans.
Then look at the provider's network partners inside Serbia. A plan that rides on the country's #1 carrier will have noticeably better rural signal than one that rides on the #3 carrier, even if the advertised speeds look identical. Our country pages list the specific carriers each plan connects to.
When a physical SIM still wins
If you need a local phone number to receive OTP SMS (banking, Grab, Uber Eats, some hotels), or you're staying longer than 30 days, a local prepaid SIM from a convenience store still beats eSIM on value. For everything else in 2026, eSIM is the default.
Activation tips
- Install the eSIM 24 hours before your flight — activation is instant, but the plan clock usually only starts on first network connection in Serbia.
- Label the line "Serbia travel" in Settings so you don't accidentally leave it as default after the trip.
- Turn your home line's data roaming OFF; keep it on for calls/SMS only.
- Save the provider's support chat URL offline in case you land without signal.
What is specific to Serbia
The Western Balkans roaming deal does not help travel eSIMs
The WB6 agreement gives free roaming between Serbia, Bosnia, Montenegro, North Macedonia, Albania and Kosovo — but only for SIMs issued in those countries. A travel eSIM bought abroad is governed by its own coverage list.
Belgrade café wifi is genuinely everywhere
The city has an unusually dense café culture with free wifi as standard, which meaningfully reduces how much mobile data a typical visitor burns through.
Kosovo is a separate coverage entry
Whatever your view of its status, eSIM providers list Kosovo separately from Serbia. If your route includes Pristina, check that it is named explicitly.
Serbia eSIM questions
Does an EU or Europe eSIM cover Serbia?+
Frequently not. Serbia is outside the EU and EEA, so EU roaming does not apply and many Europe-branded plans exclude it. Confirm Serbia appears in the coverage list before buying.
Is one plan enough for Serbia, Bosnia and Montenegro?+
Yes, if it is a Balkans regional bundle that names all three. The Western Balkans free-roaming agreement between these countries applies to their own local SIMs, not to travel eSIMs, so you cannot rely on it to bridge the gap.
How much data do I need for Serbia?+
Three to five gigabytes for a week. Belgrade's café wifi is abundant enough that most visitors use less mobile data here than in comparable European cities.
