Best eSIM for Serbia

Belgrade's fortress overlooking the Sava and Danube, Novi Sad's summer festival crowds, the quiet monasteries scattered through Šumadija — Serbia rewards travelers who move around, and a data plan that only half-covers the country isn't much use. Home-carrier roaming here is either switched off entirely or billed at rates that make even light map-checking expensive, which is why most visitors land on a local eSIM instead. We checked live pricing across 122 providers we track for Serbia, and the spread runs from well under a dollar up to premium unlimited month-long plans — here's what actually holds up today.

Quick-answer picks

• Cheapest way to get connected: Stellar eSIM's 0.5GB/7-day plan at $0.76.
• Best true bargain, full stop: abesteSIM's unlimited day-pass at $0.41 — one of the cheapest genuinely unlimited rates we track for any country, not just Serbia.
• Best value for a week: 4S eSIM's 3GB/7-day plan at $2.62.
• Best value for a month: BNESIM's 10GB/30-day plan at $8.06.
• Best-known global brand: Airalo, from $4.00 for a 3-day 1GB starter plan.

Provider-by-provider breakdown

Stellar eSIM has the cheapest realistic entry point we track for Serbia — 0.5GB for a week at $0.76 — and its bigger tiers stay competitive too, with 3GB for a month at $1.79.

abesteSIM runs the cheapest genuinely unlimited day-pass we found for Serbia, at $0.41 — cheaper than most providers' smallest fixed-GB tier, and one of the lowest unlimited day-rates we track anywhere. Real discount code active:

4S eSIM is the strongest all-round value pick for a fixed allowance — 1GB for a week at $1.37, 3GB for the same week at $2.62 — and its own unlimited week runs $5.29 if 3GB isn't enough.

BNESIM prices Serbia on a genuinely metered per-GB model — 1GB for 30 days at $1.41 scaling to 10GB for 30 days at $8.06, one of the better per-GB rates we track for a full month.

MicroEsim undercuts most of the field on its unlimited day-rate at $0.99 — genuinely cheap for an unlimited option — with a 1GB/3-day fixed tier at $1.55 if you'd rather have a short fixed allowance instead. Real discount code active:

Zwitchy sells fixed-GB tiers priced by the month rather than the day — 1GB for 30 days at $3.00, scaling to 10GB for 30 days at $11.50 — worth a look if your trip runs closer to a month than a week. Real discount code active:

Airalo is the most globally recognized name in this comparison — 1GB for 3 days at $4.00, 5GB for a month at $11.00 — priced above the local specialists but backed by wide brand recognition if that matters more to you than shaving off a dollar or two.

Why prices vary this much

A sub-dollar week-long pass and a genuinely unlimited day both show up under "Serbia eSIM," and the gap is mostly about what problem each plan solves. The cheapest fixed-GB tiers are light-use passes — fine for messaging and maps, not built for a full day of navigation and video calls. abesteSIM and MicroEsim's unlimited day-rates are genuinely unusual — most providers price unlimited well above their cheapest fixed-GB tier, not below it. BNESIM takes the opposite approach, pricing data per-GB aggressively enough on its bigger tiers that a 30-day 10GB plan can beat some providers' unlimited week rate. Brand-name providers like Airalo generally cost more everywhere, not just here — you're paying partly for a more polished app and wider name recognition, which is a real reason to pick one even if it isn't the cheapest number on the page.

If you're not sure how much data your trip actually needs, our data usage guide is worth a look before defaulting to unlimited.

Which plan fits your trip

• A short city break in Belgrade: Stellar eSIM's 0.5GB/7-day pass, or abesteSIM's unlimited day at $0.41 if you'd rather not track usage at all.
• A week that includes Novi Sad or Niš: 4S eSIM's 3GB/7-day plan at $2.62 is the standard pick.
• A longer trip covering several regions: 4S eSIM's unlimited week at $5.29 covers heavy map and video use without watching a data counter.
• A full month based in one city, light use: Zwitchy's 1GB/30-day plan at $3.00 is the cheapest way to stay reachable without paying for data you won't use.
• A full month, heavier use: BNESIM's 10GB/30-day plan at $8.06 is the better-value option among these seven for a bigger monthly allowance.

A few practical notes

Serbia's networks — A1 Srbija, Yettel Serbia, and Telekom Srbija (mts) — all show up across the providers above, with solid coverage in Belgrade, Novi Sad, and the main highway corridors; expect it to thin out in more rural stretches.

Install your eSIM before you fly — every provider above only activates once you land and connect to a Serbian network, so there's no benefit to setting it up at home. If this is your first time using an eSIM at all, our beginner's guide to how eSIMs work covers installation and activation from the very start.

Most modern phones can run an eSIM alongside your regular home SIM rather than replacing it, so you can keep your usual number reachable for calls and texts while your data runs through the cheaper local plan — worth checking your phone's dual-SIM settings before you land, and our compatibility guide if you're not sure your phone supports eSIM at all. A physical local SIM is still an option on arrival, but it means finding a shop, showing ID, and a phone number you'll only use once — most travelers find the eSIM route faster once it's set up.

Serbia isn't in the EU or Schengen, so don't assume an EU roaming plan from a neighboring country will cover it — check pricing here specifically, and if your trip continues elsewhere in the Balkans, do the same for each stop rather than assuming one plan carries over; our multi-country trip planner can show you real plans that genuinely cover your whole route if one exists.

Prices on this page are pulled live from our own tracked catalog rather than typed in by hand, so the exact numbers you see may move slightly week to week as providers adjust their own rates — that is expected, and the point of linking real, current pricing instead of a snapshot that goes stale.
