eSIM Serbia
Best eSIM for Serbia: 8 Providers Ranked
Apr
Serbia is one of Europe’s most underrated travel destinations.
Belgrade alone makes the trip worth it.
Between the fortress at Kalemegdan, the nightlife on Savamala’s floating river clubs, and day trips to Novi Sad or Tara National Park, you’ll burn through mobile data faster than you expect. Having data ready the moment you land at Belgrade Nikola Tesla Airport is the difference between a smooth arrival and 30 minutes of scrambling for airport Wi-Fi.
There’s one detail about Serbia connectivity that most comparison pages skip entirely, and it changes which provider makes sense for your trip. Here’s our full breakdown of the top eSIM options for Serbia.

Cons

Airalo: widest plan selection for Serbia
| Rating: | |
| Supported networks: | 4G, LTE |
| Countries covered: | 200+ |
| Starting price: | $4.00 / 1 GB / 3 days |
Airalo offers the widest plan selection for Serbia, with 18 different combinations of data and validity. Whether you need 1 GB for a quick Belgrade stopover or 20 GB for a month-long stay, Airalo has an option that fits. It’s one of the most recognised travel eSIM providers globally, with users from the United States, United Kingdom, and Australia regularly using it for European trips. That flexibility is hard to match on any other provider.
Network Coverage
Airalo connects to the A1 network in Serbia.
Data Plans
Eighteen plans across 3, 5, 7, 10, 15, and 30-day validity windows give you precise control over your spending. The 5 GB / 30-day plan at $11.00 is competitive with eSIM4’s $9.98 equivalent. Where Airalo really stands out is mid-range: 10 GB at $17.00 for 15 days is strong value if your trip fits that window.
Activation Process
Airalo’s mobile app is one of the most polished in the eSIM space. Clear step-by-step QR code guidance makes setup straightforward, even for first-time eSIM users. You can manage your eSIMs directly in the app: view data remaining, top-up, or buy a new eSIM for your next destination. Install before departure and activate on arrival in Serbia.

Saily: unlimited data with built-in privacy tools
| Rating: | |
| Supported networks: | 4G, LTE |
| Countries covered: | 150+ |
| Starting price: | $3.99 / 1 GB / 7 days |
Saily offers a 15-day unlimited data plan for Serbia. Built by the NordVPN team, it also includes privacy tools like an ad blocker, virtual location, and web protection. The combination of eSIM data and built-in security tools is unique on this list. For digital nomads working from Belgrade’s cafes and coworking spaces, or anyone connecting to hotel Wi-Fi networks, those extras have real value.
Network Coverage
Saily does not publish which local network it uses in Serbia.
Data Plans
Twelve plans from 1 GB / 7 days through to unlimited / 30 days. The Saily eSIM unlimited plan at $48.99 for 15 days is worth considering if you’re streaming, working remotely, or attending a multi-day event like EXIT Festival where you’ll burn through data quickly. For travellers who want to use in Serbia a 5GB plan, Saily’s $10.99 option is competitive. The capped plans are priced almost identically to eSIM4, making Saily a strong alternative if built-in privacy tools matter to you. Many users recommend Saily as the best eSIM for Serbia when privacy and unlimited data are the priority.
Activation Process
Clean QR code activation through the Saily app. The NordVPN team’s polish shows in the setup flow. Install before your flight and the privacy features activate alongside your data connection when you land in Serbia.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 days | $3.99 |
| 3 GB | 30 days | $7.99 |
| 5 GB | 30 days | $10.99 |
| 10 GB | 30 days | $17.99 |
| 20 GB | 30 days | $26.99 |
| Unlimited | 15 days | $48.99 |
Pros
- Unlimited data available: 15-day unlimited plan at $48.99 for heavy users
- Built-in privacy tools: ad blocker, virtual location, and web protection included
- Backed by NordVPN: strong privacy track record and polished app design
Cons
- Unlimited plan is pricey: $48.99 for 15 days is a steep jump from the capped plans
- Fewer countries: 150+ vs. 200+ for Airalo or Nomad
Nomad: largest data plans and unlimited daily option
| Rating: | |
| Supported networks: | 4G, LTE |
| Countries covered: | 200+ |
| Starting price: | $4.00 / 1 GB / 7 days |
Nomad’s plan range for Serbia goes all the way up to 50 GB for heavy users. It also has a 5-day unlimited plan. For digital nomads based in Belgrade or anyone doing a longer Balkans trip, Nomad’s range is hard to beat. Regional and global eSIM packages are also available, which helps if Serbia is one stop on a wider European itinerary.
Network Coverage
Nomad connects to the A1, Yettel and mts networks in Serbia.
Data Plans
Eight plans, from 1 GB / 7 days all the way to 50 GB / 30 days and two unlimited options. The 20 GB plan at $21.00 is genuinely strong value for extended stays. The 5-day unlimited plan at $26.00 is useful for short, data-intensive visits like attending EXIT Festival in Novi Sad.
Activation Process
Straightforward QR code activation through the Nomad app. The setup flow is clean and plan management is easy to navigate. Install before your flight and activate on arrival.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 days | $4.00 |
| 3 GB | 30 days | $7.00 |
| 5 GB | 30 days | $10.00 |
| 10 GB | 30 days | $15.00 |
| 20 GB | 30 days | $21.00 |
| 50 GB | 30 days | $35.00 |
| Unlimited | 5 days | $26.00 |
Pros
- 50 GB option: tied for the largest capped plan available for Serbia on this list
- 5-day unlimited: ideal for short, data-heavy trips like EXIT Festival
- Strong mid-range value: 20 GB at $21.00 is competitive pricing
Cons
- Unlimited only lasts up to 10 days: no longer-term unlimited option
- Entry plan is pricier: $4.00 for 1 GB vs. $2.98 from eSIM4
GigSky: straightforward plans with Apple integration
| Rating: | |
| Supported networks: | 4G, LTE |
| Countries covered: | 180+ |
| Starting price: | $2.99 / 1 GB / 7 days |
GigSky keeps things simple with four capped plan tiers for Serbia, plus unlimited plans. Originally an Apple partner, it has a strong track record with iPhone users. If you want a no-fuss setup, GigSky is worth considering.
Network Coverage
GigSky does not publish which local network it uses in Serbia.
Data Plans
Four capped plans from 1 GB / 7 days to 10 GB / 30 days, plus unlimited plans from 1 to 30 days. The 5 GB plan at $10.29 is close to eSIM4 ($9.98) and Nomad ($10.00) at the same tier.
Activation Process
After buying a Serbia plan, you get twelve months to install it. Setting up a different device? A QR code and an activation code from GigSky’s app handle that. This phone, by contrast, installs with the app’s Install on this device button. GigSky then asks for roaming on and an APN of gigsky.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 days | $2.99 |
| 3 GB | 15 days | $7.49 |
| 5 GB | 30 days | $10.29 |
| 10 GB | 30 days | $16.79 |
Pros
- Apple integration: installs on iPhone through the GigSky app
- Simple plan structure: four capped tiers plus unlimited, no decision fatigue
- Established provider: one of the earliest eSIM companies with a long track record
Cons
- Slightly higher at mid-range: 5 GB at $10.29 vs. $9.98 from eSIM4
- Only 4 capped plans: tops out at 10 GB
Jetpac: essential apps keep working after data runs out
| Rating: | |
| Supported networks: | 4G/5G (multi-network) |
| Countries covered: | 200+ |
| Starting price: | $5.50 / Unlimited / 1 day |
Jetpac’s standout feature for Serbia is that WhatsApp, Google Maps, and essential navigation apps continue working even after your data allowance runs out. In a country where CarGo (Serbia’s ride-hailing app) and Google Maps are essential for getting around Belgrade, that safety net matters. For travellers who regularly run out of data mid-trip, this is the first option worth serious consideration.
Network Coverage
Jetpac’s help centre lists Telenor as its Serbia network.
Data Plans
Capped plans run from 1 GB / 4 days to 40 GB / 30 days, plus unlimited plans from 1 to 30 days. The 1 GB entry plan costs $7.00, the highest on this list. 5 GB at $20.00 costs about twice eSIM4 ($9.98).
Activation Process
A Serbia pack bought weeks ahead is safe, because Jetpac holds unactivated packs for 3 months. Prefer to type? Jetpac’s email lists the codes for a manual install. Switch-on waits until you land in Serbia, and data roaming goes on at the same time. From then on, the Jetpac eSIM should handle mobile data.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 4 days | $7.00 |
| 3 GB | 7 days | $10.00 |
| 5 GB | 30 days | $20.00 |
| 10 GB | 30 days | $40.00 |
Pros
- Essential apps after data runs out: WhatsApp and Google Maps keep working at zero data
- Cheapest unlimited start: 1 day of unlimited data for $5.50
- Packs keep for 3 months: unactivated packs stay in your account for 3 months
Cons
- Higher prices: 5 GB at $20.00 is about twice the eSIM4 price
aloSIM: solid mid-range plans with a money-back guarantee
| Rating: | |
| Supported networks: | 4G, LTE |
| Countries covered: | 200+ |
| Starting price: | $4.50 / 1 GB / 7 days |
aloSIM offers a 100% money-back guarantee on its Serbia plans, which is unusual for a travel eSIM provider. If it doesn’t work for you, you get a full refund. That guarantee removes the risk of buying an eSIM for a country you’ve never tested before. The customer support team is responsive, with live chat available for troubleshooting if you run into activation issues. The pricing is competitive at mid-range, and the data packages for Serbia are broader than GigSky.
Network Coverage
aloSIM connects to the A1 and Telenor networks in Serbia.
Data Plans
Six plans from 1 GB / 7 days to 20 GB / 30 days, plus unlimited from $20.50 for 3 days. The 3 GB plan at $8.00 and 5 GB at $11.00 sit in a comfortable mid-range. Its 20 GB tier ($27.00) suits longer stays or heavier data use.
Activation Process
For a manual install, the aloSIM app gives two codes to paste into your phone. Its QR option works by scanning a code shown on a separate screen. Neither step starts the package, which waits for a supported Serbian network. Leave the eSIM’s data and roaming settings until departure day, then turn both on.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 days | $4.50 |
| 2 GB | 15 days | $6.50 |
| 3 GB | 30 days | $8.00 |
| 5 GB | 30 days | $11.00 |
| 10 GB | 30 days | $18.00 |
| 20 GB | 30 days | $27.00 |
Pros
- Money-back guarantee: full refund if the eSIM doesn’t work for you
- Unlimited option: from $20.50 for 3 days to $99.00 for 30 days
Cons
- Mid-range pricing: slightly more than eSIM4 on comparable tiers
Roamless: one eSIM that never expires
| Rating: | |
| Supported networks: | 4G, LTE |
| Countries covered: | 200+ |
| Starting price: | $3.95 / 1 GB / 30 days |
Roamless uses a different model from every other provider on this list: you activate one global eSIM, and it never expires. Buy data when you need it, use it across 200+ countries including Serbia. For frequent travellers who visit the Balkans regularly, installing a single eSIM once and topping up for each trip is genuinely convenient. It’s a strong option if you use your physical sim card for calls and texts at home, and simply want a reusable travel eSIM for internet access abroad. You can keep both active on a dual SIM smartphone without switching between profiles.
Network Coverage
Roamless connects to the Yettel network in Serbia.
Data Plans
Capped plans run from 1 GB / 30 days to 20 GB / 30 days. All capped plans come with 30-day validity, which is generous for the smaller tiers. The 10 GB plan at $28.45 is the second most expensive on this list for that tier. However, the “never expires” eSIM profile means you don’t need to install a new one for your next trip to Serbia or anywhere else.
Activation Process
Extra data in Serbia can come from another Roamless plan valid there, on the same eSIM. Setup itself takes one click on Install Now, inside the app for iPhone or Android. Data roaming on the Roamless line is a must after arrival.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 30 days | $3.95 |
| 2 GB | 30 days | $6.95 |
| 3 GB | 30 days | $8.45 |
| 5 GB | 30 days | $13.95 |
| 10 GB | 30 days | $28.45 |
Pros
- Never expires: activate once, top up whenever you travel again
- 30-day validity on all capped plans: generous even on the smallest tier
- Credit never expires: pay-as-you-go credit has no expiry date
Cons
- 10 GB is expensive: $28.45 is the second highest on this list for that tier
- Higher per-GB cost: mid-range plans are pricier than eSIM4, Airalo, or Nomad

What to know before visiting Serbia
Belgrade has excellent 4G coverage throughout the city
Walking Knez Mihailova, climbing Kalemegdan Fortress, or bar-hopping through Savamala, you’ll have consistent 4G signal. Serbia’s mobile infrastructure in Belgrade is strong, with all three major carriers (MTS, Telenor, A1) providing solid urban coverage. Novi Sad and Nis are similarly well-covered. Most comparison pages gloss over this, but Serbia’s urban connectivity is genuinely on par with Western European capitals.
Serbian Dinar is the currency, but EUR is widely accepted
The official currency is the Serbian Dinar (RSD). ATMs are everywhere in Belgrade and Novi Sad, and most tourist-facing restaurants and shops accept cards. In popular areas like Stari Grad and Dorcol, many places also accept euros, though you’ll typically get a worse exchange rate paying in EUR. Carry some dinar cash for smaller establishments, taxis, and market stalls.
CarGo is Serbia’s ride-hailing app (Uber does not operate here)
This catches most travellers off guard. Uber pulled out of Serbia, so the default ride-hailing app is CarGo. Download it before you arrive and you’ll need mobile data to use it. Belgrade taxis are notoriously unreliable on metering, so having CarGo with a working data connection protects you from overcharging. The app works like Uber: set your destination, get a fixed price, pay through the app.
EXIT Festival causes real network congestion
EXIT Festival in Novi Sad is one of Europe’s biggest music festivals, drawing 200,000+ attendees over four days each July. During the event, mobile networks in and around the Petrovaradin Fortress get genuinely congested. Messages take longer to send, maps load slowly, and video calls become unreliable. If you’re attending EXIT, an unlimited data plan is worth the investment, not because you’ll use more data, but because congested networks require more retries to push data through.
Tara National Park and Derdap Gorge have limited signal
Serbia’s main outdoor destinations sit in mountainous terrain where mobile coverage thins out. Hiking trails in Tara National Park and along the Derdap Gorge frequently lose signal entirely. Download offline maps for the Tara and Derdap regions before you leave Belgrade. Save any accommodation details and trail information locally on your phone.
No VPN restrictions and all social media works
Serbia has no internet censorship, no VPN restrictions, and no blocked social media platforms. WhatsApp, Instagram, Facebook, TikTok, YouTube, and every messaging app works without restrictions. Unlike some neighbouring countries, you don’t need to worry about content filtering or geo-blocking when using a Serbian mobile connection.
English is widely spoken by younger people in Belgrade
In Belgrade’s tourist areas, restaurants, and hostels, English communication is rarely a problem. Younger Serbians, especially in the service industry, speak English well. Outside Belgrade and in rural areas, English drops off significantly. Having Google Translate downloaded for offline use is a practical backup. Serbian uses both Cyrillic and Latin scripts, so street signs may appear in either alphabet.
Serbia is not in the EU, so different roaming rules apply
If you’re coming from an EU country, your home carrier’s “Roam Like at Home” policy does not apply in Serbia. EU roaming regulations end at the Serbian border. This means standard international roaming charges on your home SIM will apply, which can be extremely expensive. An eSIM is the simplest way to avoid surprise roaming bills when crossing from EU neighbours like Hungary, Romania, or Croatia into Serbia.
How to activate a Serbia eSIM
Setting up an eSIM for Serbia is straightforward. Most modern smartphones support eSIM technology (iPhone XS and later, Samsung Galaxy S20+, Google Pixel 3+), so compatibility is rarely an issue. The eSIM is a digital SIM (embedded SIM) built into your phone, so there is no physical SIM card to swap. If your smartphone supports dual SIM, you can keep your home SIM active for calls and texts while using your Serbia eSIM for mobile data. We recommend setting up your prepaid eSIM before your flight so you arrive in Belgrade already connected.
QR code activation (most common)
- Purchase your Serbia eSIM plan on the provider’s website or app
- Receive your QR code by email (usually instant)
- On your phone: Settings → Cellular / Mobile Data → Add eSIM → Scan QR Code
- Set the eSIM as your data line and label it “Serbia Travel” for easy identification
- Toggle it on when your flight lands at Belgrade Nikola Tesla Airport
App-based activation
- Download the provider’s app (eSIM4, Airalo, Saily, etc.)
- Create an account and purchase a Serbia plan
- Follow the in-app installation steps, which walk you through your phone’s settings
- Activate when you arrive in Serbia
Manual activation
- Go to Settings → Cellular → Add eSIM
- Select “Enter Details Manually”
- Enter the SM-DP+ address and activation code from your confirmation email
- Confirm and install; the profile downloads in under a minute
How to make calls with an eSIM in Serbia
Most Serbia eSIMs on this list are data-only, which means you’ll rely on apps for voice and video calls. For most travellers this works well because WhatsApp and Viber are both popular in Serbia. Two providers stand out: eSIM4 offers calls and texts through its Yabb companion app (paid add-on), and Roamless includes a phone number and calling within its global eSIM.
For calls back home or to Serbian businesses, use:
- WhatsApp: widely used in Serbia for both personal and business communication. WhatsApp calls and messages work over your eSIM data connection.
- Viber: more popular in Serbia than in most Western countries. Many local businesses use Viber for bookings and enquiries.
- FaceTime / Google Meet: works well over 4G in Belgrade and Novi Sad for video calls.
If you specifically need a local Serbian telephone number, Roamless includes one with its global eSIM. Alternatively, you can buy a local prepaid SIM card from MTS, Telenor, or A1 at Belgrade airport or any kiosk in the city. Registration requires your passport. Using your physical SIM alongside a travel eSIM is straightforward on any dual SIM smartphone: keep your home number active on the physical SIM and use the eSIM for mobile broadband data in Serbia.
Our final verdict
For most travellers heading to Serbia, eSIM4 is the strongest all-round option. It has the lowest starting price on this list ($2.98), reliable 4G across Belgrade and Novi Sad, and you can have it set up before your flight. Landing at Belgrade airport with CarGo ready, Google Maps loaded, and WhatsApp working is exactly the start you want.
Serbia is not in the EU, so your home carrier’s EU roaming deal almost certainly does not cover it. Set up your eSIM before you fly and you will land already online.
Frequently Asked Questions (FAQs)
eSIM4 is our recommended provider for Serbia. It offers the lowest starting price ($2.98 for 1 GB / 7 days) and reliable 4G coverage across Belgrade and Novi Sad. A 3 to 5 GB plan suits most week-long visits.
Yes. All eight providers on this list offer eSIM plans that work in Serbia. Coverage across Belgrade, Novi Sad, and Nis is strong on 4G. Signal becomes patchy in mountainous areas like Tara National Park and Derdap Gorge, but urban connectivity is reliable and comparable to Western European cities.
Serbia eSIM plans start from $2.98 for 1 GB / 7 days. Cheapest eSIM plans for Serbia come from eSIM4, GigSky, Roamless, and Saily, all starting under $4.00. For a typical one-week trip with moderate data use (maps, messaging, social media), a 3 to 5 GB plan is enough.
Yes, but with heavy congestion. Novi Sad has strong 4G coverage, and the Petrovaradin Fortress area is well-covered under normal conditions. During EXIT Festival, with 200,000+ attendees concentrated in one area, networks get noticeably slower. An unlimited plan helps because congested networks require more retries to push data through.
Our Methodology
We did not test these eSIMs on the ground in Serbia. Every provider on this list went through the same desk review of its live Serbia page, covering the points below.
Network carrier verification: We checked which Serbian carrier each provider routes through by reviewing their live country pages. Serbia has three major carriers (MTS, Telenor, A1), and the carrier determines your coverage footprint in different parts of the country.
Plan structure analysis: We compared data allowances, validity periods, pricing tiers, and per-GB cost across every available plan. We flagged providers with unlimited options (eSIM4, Saily and Nomad) and checked whether unused data carries over or expires at the end of the validity window.
Feature audit: We verified hotspot support, activation method (QR code, app-based, or manual), multi-device compatibility, and whether each provider offers calls and texts or data only. We also checked for extras like built-in VPNs, money-back guarantees, and voice calling features.
Coverage mapping: We cross-referenced each provider’s network against known coverage areas for key Serbia travel destinations: Belgrade city centre, Novi Sad, the E75 motorway corridor, Tara National Park, and Derdap Gorge.
Pricing benchmarked: We pulled current pricing from each provider’s website and compared equivalent plans side by side. The pricing tables in this guide reflect what you’ll pay at checkout, not promotional or introductory rates.
