Buying cheap data in Serbia, and the roaming trap at the border

The thing that catches European visitors out

Serbia is not in the EU. Roam-like-at-home does not apply, and a plan from Germany, Italy or Croatia that costs you nothing across the rest of the region will bill you at roaming rates the moment you cross in. Some operators bundle Western Balkan roaming and some sell an add-on; most do neither by default. Check before you travel, because this is the single most expensive assumption you can make about Serbia.

That also makes Serbia one of the few countries in this part of Europe where a travel eSIM is worth buying for everyone, not just for visitors from outside the continent.

What data actually costs

The honest floor is $0.70 a gigabyte, and it is on the largest plan in the market rather than the cheapest one. This page has carried two wrong floors before this one: $2.00, which came from generated text, and $0.98, which was right for Airalo but published while Nomad's prices sat unchecked.

Airalo's rows were read from its own site on 13 August 2026, Nomad's from its own on 18 August. The Saily row comes from our older records and has not been re-checked.

The 50 GB plans are the ones to notice. Nomad's is two and a half times the size of the next tier down for less than twice the money, and it and Airalo's are the only plans in Serbia under a dollar a gigabyte. If you are here for a month, or working, or sharing a connection with anyone, it is the cheapest data on offer by a wide margin.

Where the value collapses

Serbia has an unusually wide spread between the good and the bad buys, so the provider you pick matters more here than in most countries.

This section used to say Nomad was expensive in Serbia, quoting small and mid-sized plans at two to three times what Nomad actually charges. Those figures had never been read off Nomad's site. They have now been, and the opposite is true: Nomad is the cheapest seller in the country at every size, and the spread that made this section worth writing is mostly gone. Holafly's unlimited passes are verified at $27.90 for 5 days, $39.50 for 10 — defensible for a short, heavy trip, poor value against 50 GB for anything longer. Holafly sells six windows and no others — 3, 5, 7, 10, 15 and 30 days — so the 25-day plan this page used to list does not exist.

The counter at Belgrade, and the passport

A tourist SIM at the airport runs about $14. Belgrade Nikola Tesla (BEG) has Yettel and A1 counters in T2 arrivals. In town, mts, Yettel and A1 all have stores around Terazije and Knez Mihailova, and a city shop will give you more plan choice than an arrivals counter does.

A passport is required to register a prepaid SIM in Serbia. Budget a few minutes for the paperwork at the counter.

Is the local SIM worth it? For a short visit, no — $14 at arrivals buys an unpublished allowance, while a verified 5 GB eSIM for 30 days is $10 and installs before you land. For a long stay it is closer, and a Serbian number has real uses of its own for bookings, deliveries and verification codes.

Networks: what we know and what we do not

Serbia has three operators: Telekom Srbija, which retails as mts, plus Yettel Serbia and A1 Serbia. All three cover the cities and the motorway network well.

Which of them a travel eSIM actually roams onto is a separate question, and we are not able to answer it. Airalo does not publish a host network for Serbia; "Serbia Mobile" is the name the plan is sold under at checkout, not a carrier. Nomad and Saily publish none either. Holafly's own listing names A1, Yettel and mts, but nobody has confirmed it against the operators. Treat it as sales copy. If your trip depends on a specific network, buy that network's own SIM in its own shop.

Where the signal drops

Coverage gaps are rural and remote: the Stara Planina range, some of the deeper sections of the Djerdap gorge, and very rural villages in the south. The Kosovo border area operates on separate networks, which is worth knowing if you plan to cross. Emergency calls work on any Serbian network without an active plan.

What we would buy

A few days and light use: the cheapest entry plans are around $4. A week or two of ordinary travel: 10 GB at roughly $18 verified. Anything longer, heavier, or shared: the 50 GB plan at $49, which is the only genuinely cheap data in the country.

The complete ladder of sizes and durations is on the Serbia hub. If you are not sure your phone takes an eSIM, settle that first with our eSIM compatible phones list.
