For most travelers looking for a simple international eSIM for Serbia, Nomad currently offers one of the strongest combinations of price, data allowance and network flexibility. Its 10GB plan costs $15 for 30 days, while 20GB costs $21 and 50GB costs $35, making it particularly competitive for a typical one- or two-week trip.
Travelers who want unlimited data have several alternatives rather than just one: Airalo and Holafly both sell unlimited Serbia packages, while Saily remains useful for smaller fixed-data plans and travelers who value its built-in security features.
There is another option that is easy to miss when comparing international travel eSIMs. Serbia’s local operators now sell eSIM products as well, and their tourist packages can provide dramatically more data for the money. Telekom Srbija’s mts, for example, currently offers a Super Tourist option with 500GB valid for 30 days, while Yettel sells a 50GB tourist package that can also be purchased as an eSIM.
The best choice therefore depends less on which eSIM brand is most famous and more on how much data you need, whether you are visiting only Serbia or several Balkan countries, and whether you prefer the simplicity of an international travel eSIM over a local Serbian mobile plan.
Best eSIMs for Serbia: Quick Comparison
- Nomad: 1GB / 7 days for $4, 10GB / 30 days for $15, 20GB / 30 days for $21 and 50GB / 30 days for $35. Best for overall value among international fixed-data eSIMs.
- Saily: 1GB / 7 days for $3.99, 5GB / 30 days for $10.99 and 10GB / 30 days for $17.99. Best for light users and travelers who want additional security features.
- Airalo: Fixed-data packages start at $4, while unlimited plans start at $18.50 for three days. Best for flexible trip lengths and travelers who want both fixed and unlimited options in one app.
- Holafly: Unlimited data from $18.90 for three days, with access to A1, Yettel and Telekom Srbija. Best for travelers who prioritize unlimited data and multi-network access.
- mts Tourist eSIM: Local option with very large data allowances, including 500GB for 30 days with the Super Tourist package. Best for longer stays and heavy data users staying mainly in Serbia.
- Yettel Tourist eSIM: 50GB for 30 days for 1,399 RSD, including a smaller Western Balkans roaming allowance. Best for travelers who want a Serbian eSIM with local pricing.
Prices and packages were checked in August 2026. eSIM pricing, promotional allowances and fair-use conditions can change quickly, so always confirm the final package details before paying.
Our Quick Recommendation
If you want an international travel eSIM that you can install before departure without dealing with a Serbian mobile operator, Nomad is currently the strongest overall value for most travelers. A 10GB allowance is enough for many one- or two-week trips, while its 20GB and 50GB plans remain competitively priced if you use your phone more heavily.
If you specifically want unlimited data, compare Airalo and Holafly rather than automatically choosing Holafly. Airalo is currently cheaper for several trip lengths, while Holafly’s main advantage is access to all three major Serbian networks and a straightforward unlimited-data product.
For travelers spending most or all of their trip in Serbia, however, a local mts or Yettel eSIM deserves serious consideration. Local tourist packages offer substantially larger data allowances than most international providers, which can make them the better value once convenience is no longer the only priority.
Does eSIM Work in Serbia?
Yes, eSIM works well in Serbia, and the country’s mobile infrastructure improved significantly after commercial 5G services became available. Serbia’s three national mobile operators — Telekom Srbija under the mts brand, Yettel and A1 Serbia — all received spectrum licenses enabling commercial 5G services in December 2025.
By August 2026, Serbia’s electronic communications regulator reported more than 2,300 active 5G base stations across the country, so describing 5G as something available only experimentally in a handful of central-city locations is no longer accurate.
Travel eSIM providers connect through these Serbian networks rather than operating their own mobile infrastructure. Airalo currently lists A1 as the primary network for its Serbia eSIM, while Nomad advertises access to Yettel, A1 and mts depending on the plan, and Holafly lists all three operators.
In Belgrade, Novi Sad, Niš and other populated areas, mobile connectivity is generally straightforward, while coverage can become less predictable in mountainous terrain, deep valleys and sparsely populated rural regions. If you are planning a road trip through western, eastern or southern Serbia, downloading offline maps remains useful even if you have a large or unlimited data package.
Best eSIM Options for Serbia
Nomad — Best Overall Value
Nomad is currently the strongest international eSIM option for travelers who want a fixed amount of data at a competitive price. Its Serbia packages start at $4 for 1GB valid for seven days, while the more useful medium and larger packages cost $7 for 3GB, $10 for 5GB, $15 for 10GB, $21 for 20GB and $35 for 50GB.
That pricing makes Nomad particularly attractive around the 10–50GB range, where it currently undercuts several major competitors. A traveler spending ten days in Serbia and using maps, messaging, social media, restaurant searches and occasional video could comfortably choose 10GB or 20GB without paying for an unlimited package that may never be necessary.
Nomad also advertises 4G and 5G connectivity and lists Yettel, A1 and mts among the networks available in Serbia, although the exact network combination can depend on the specific plan. Hotspot and tethering are supported, which makes it more useful than some unlimited products if you occasionally need to connect a laptop or another device.
Another practical advantage is activation. You can install the eSIM in advance, while the plan begins when it connects to the supported destination network. Nomad currently requires the plan to be activated within 60 days of purchase, so buying it shortly before the trip is simpler than purchasing it months ahead.
- Best for: Travelers who need 5–50GB and want a strong balance between price, network access and hotspot functionality.
- Main advantage: Very competitive fixed-data pricing and access to multiple Serbian networks depending on the plan.
- Potential drawback: Network availability can vary between individual Nomad packages, so check the plan details before purchase.
Saily — Best for Light Users and Security Features
Saily is particularly competitive for travelers who do not need a huge amount of data. Its current Serbia packages include 1GB for seven days at $3.99, 3GB for 30 days at $7.99, 5GB for $10.99, 10GB for $17.99 and 20GB for $26.99.
Nomad is currently slightly cheaper at several larger data levels, so price alone is not the strongest reason to choose Saily. Its main differentiator is the software layer built around the eSIM, including features designed to reduce ads and trackers and provide virtual-location functionality.
Saily supports 3G, 4G, LTE and 5G depending on the local partner network, and its current Serbia product does not impose a specific hotspot restriction. Plans activate automatically when the eSIM connects at the destination, although purchases have a 30-day activation period, after which a plan may activate automatically even if you have not reached Serbia yet.
Saily has also expanded beyond purely data-only functionality. Calling and SMS bundles can now be associated with a Saily phone number, although travelers who only need internet can continue using WhatsApp, FaceTime and similar apps without purchasing voice services.
- Best for: Light and moderate data users, especially those who value security-related app features.
- Main advantage: Affordable small packages, unrestricted hotspot use and convenient automatic activation.
- Potential drawback: Its medium and large fixed-data packages are currently slightly more expensive than Nomad’s equivalents.
Airalo — Best for Flexible Fixed and Unlimited Plans
Airalo is no longer simply a fixed-data budget option in Serbia. It now offers both standard data packages and unlimited plans, making it one of the most flexible choices if you prefer to keep everything within one familiar eSIM app.
Current fixed packages include 1GB for three days at $4, 3GB for seven days at $8, 5GB for seven days at $10 and 10GB for seven days at $16.50. Longer 30-day packages include 5GB for $11, 10GB for $18, 20GB for $27 and 50GB for $49.
Unlimited packages are also available, starting at $18.50 for three days and increasing to $33.50 for seven days, $48 for 15 days and $95 for 30 days. The important detail is that unlimited does not necessarily mean unlimited full-speed usage: Airalo’s current Serbia unlimited product reduces speeds to 1 Mbps after 3GB of usage within a day.
Airalo lists A1 as the primary Serbian network for this product. For travelers staying in cities, that may be perfectly adequate, but those taking long road trips may prefer a provider such as Nomad or Holafly that advertises access to multiple Serbian operators.
- Best for: Travelers who want a broad choice of validity periods and the option to switch between fixed-data and unlimited packages.
- Main advantage: Large selection of plan sizes and trip lengths in an established eSIM app.
- Potential drawback: Unlimited packages have a daily high-speed fair-use threshold, while fixed packages are not always the cheapest option.
Holafly — Best for Unlimited Data and Multi-Network Coverage
Holafly remains a strong option for travelers who specifically want unlimited data and prefer not to calculate whether 10GB or 20GB will last until the end of the trip. Its Serbia eSIM currently costs $18.90 for three days, $27.90 for five days, $33.90 for seven days, $39.50 for ten days, $54.90 for 15 days and $106.50 for 30 days.
The strongest argument for Holafly is not necessarily price, because Airalo currently offers cheaper unlimited packages for several trip lengths. Instead, Holafly lists all three Serbian networks — A1 Serbia, Yettel Serbia and Telekom Srbija — giving the eSIM more potential network flexibility as you move around the country.
Holafly supports 5G where the local network makes it available and allows hotspot sharing of up to 1GB per day. That is enough for occasional laptop use or sharing a connection with another traveler, but it is an important limitation for remote workers who expect to tether several gigabytes every day.
The word unlimited should also never be interpreted as a guarantee of permanently unrestricted maximum speed, since network management and fair-use policies can still apply. If you intend to stream heavily or use the phone as your main work connection, compare those conditions before choosing an unlimited product purely on the headline allowance.
- Best for: Heavy phone-data users who want an unlimited plan and access to multiple Serbian networks.
- Main advantage: Unlimited data combined with A1, Yettel and Telekom Srbija network access.
- Potential drawback: More expensive than most fixed-data plans, with hotspot sharing limited to 1GB per day.
Local Serbia eSIMs: Are They Better Than Travel eSIMs?
International eSIMs are convenient because they can be purchased through a familiar global provider before departure, but Serbia’s local mobile operators now offer eSIM options that can be considerably better value if Serbia is your main destination.
This changes the usual travel-eSIM comparison. You no longer necessarily have to choose between installing an eSIM before your flight and visiting a Serbian phone shop for a physical SIM after arrival, because both mts and Yettel offer eSIM-based prepaid products.
mts Super Tourist eSIM — Best for Huge Data Allowances
Telekom Srbija’s mts currently offers one of the most striking local deals. Its Super Tourist SIM package includes 500GB of maximum-speed internet valid for 30 days and costs 2,150 RSD, and the operator allows the package to be purchased as an eSIM.
For a traveler who is staying in Serbia for several weeks, working remotely or consuming a large amount of mobile data, this is difficult for international travel eSIM providers to match on a price-per-gigabyte basis.
There is also a shorter Tourist SIM option containing 150GB valid for five days at 700 RSD, again with an eSIM purchase option. The enormous headline allowances make local mts particularly attractive for heavy users, although registration and local prepaid procedures introduce slightly more friction than simply buying a global travel eSIM in an app.
- Best for: Long stays, remote work and extremely heavy data consumption.
- Main advantage: Hundreds of gigabytes at local Serbian pricing, with 5G access available.
- Potential drawback: Setup and prepaid registration are less frictionless than using an international travel eSIM.
Yettel Tourist eSIM — Best Local Option for a Typical Trip
Yettel’s dedicated Tourist plan currently includes 50GB valid for 30 days for 1,399 RSD and can be purchased as an eSIM. It also includes 3.5GB that can be used within the Western Balkans region, which can be useful if your Serbia trip continues into countries such as Montenegro, Bosnia and Herzegovina, North Macedonia or Albania.
The main caveat is speed: Yettel currently advertises this particular tourist package with speeds of up to 10 Mbps. That is more than sufficient for maps, browsing, messaging, social media and ordinary video calls, but travelers who specifically want to take full advantage of Serbia’s new 5G infrastructure may prefer another plan.
- Best for: Travelers staying primarily in Serbia who want a local eSIM with enough data for an entire trip.
- Main advantage: 50GB for 30 days plus a small Western Balkans roaming allowance.
- Potential drawback: The tourist package currently has a relatively modest advertised maximum speed.
Travel eSIM vs Local eSIM in Serbia: Which Is Better?
The difference is no longer simply “eSIM versus physical SIM.” In Serbia, the more useful comparison is between an international travel eSIM and a local Serbian eSIM.
- Choose an international travel eSIM if you want the simplest possible setup before departure, already use an eSIM provider’s app or are visiting several countries during the same trip.
- Choose Nomad if you want strong fixed-data pricing and do not need hundreds of gigabytes.
- Choose Saily if you use relatively little data and value its security and privacy-related features.
- Choose Airalo if you want a broad selection of fixed and unlimited plans with different validity periods.
- Choose Holafly if unlimited data and access to several Serbian networks matter more than getting the lowest possible price.
- Choose a local mts or Yettel eSIM if Serbia is your main destination and maximizing the amount of data you receive for your money is the priority.
For a short Belgrade weekend, the difference between spending $4 and dealing with local prepaid registration is probably too small to justify extra effort. For a three- or four-week stay, however, comparing local Serbian offers can save money while giving you dramatically more data.
How Much Data Do You Need in Serbia?
Your data needs depend more on how you use your phone than on the number of days you are traveling. Someone who mainly uses Google Maps and WhatsApp may consume less during a two-week trip than another traveler uses in three days of video streaming.
- 1–3GB: Suitable for a short city break with maps, messaging, restaurant searches and light browsing.
- 5GB: A sensible allowance for approximately one week of moderate everyday use.
- 10GB: A comfortable choice for a one- or two-week trip involving regular social media, navigation and occasional video.
- 20–50GB: Better for frequent video, photo uploads, hotspot use or travelers who spend relatively little time on hotel Wi-Fi.
- Unlimited or local high-data package: Most useful for remote workers, streamers and travelers using their phone as their main internet connection.
Choosing the smallest plan is not automatically the cheapest strategy if you end up buying several top-ups. Compare the next package size before paying, especially when the price difference between 5GB and 10GB is relatively small.
Is 5G Available in Serbia?
Yes. Serbia’s 5G situation changed substantially at the end of 2025, when Telekom Srbija, Yettel and A1 received the spectrum licenses needed to begin commercial 5G services.
By 5 August 2026, Serbia’s regulator RATEL reported 2,354 active 5G base radio stations across the country. This means older travel guides describing Serbian 5G as merely an upcoming technology or something confined to a handful of trial locations are now outdated.
Whether you actually receive 5G still depends on your phone, location, local operator and the network agreement used by your travel eSIM. A provider advertising 5G does not guarantee a 5G signal at every moment, and in rural or mountainous regions you may still connect to 4G or another available network.
For most travelers, reliable coverage is more important than seeing a 5G icon on the screen. Maps, messaging, booking apps, browsing and ordinary video calls work comfortably over a good 4G connection, so network flexibility can be more useful than choosing a plan solely because it advertises the fastest possible technology.
How to Set Up an eSIM for Serbia
- Check compatibility first. Make sure your phone supports eSIM and is network-unlocked before buying a package.
- Purchase the plan while you have reliable Wi-Fi. Buying and installing the eSIM at home is usually easier than dealing with setup immediately after landing.
- Read the activation policy. Some eSIMs begin validity when they first connect to a Serbian network, while others impose a fixed deadline after purchase.
- Install the eSIM using the provider’s app or QR code. Keep the installation email or instructions available until you confirm the connection works.
- Select the eSIM for mobile data. Once in Serbia, make sure the new line is enabled and chosen as your data SIM.
- Enable data roaming for the travel eSIM. International eSIM providers usually require roaming because their products connect through Serbian partner networks.
- Disable data roaming on your home SIM. You can usually keep your normal number active for calls or verification messages while preventing accidental mobile-data roaming charges.
Installing an eSIM and activating its data plan are not always the same thing, so do not follow generic advice telling you never to install an eSIM before departure. Providers such as Nomad, Saily and Holafly allow advance installation while starting the actual plan according to their own activation rules.
Can You Use Your EU SIM in Serbia?
Serbia is not a member of the European Union, so the EU’s standard Roam Like at Home rules do not automatically apply. A SIM card that gives you free roaming across France, Italy, Germany or Croatia may therefore charge a completely different tariff once you enter Serbia.
Some European operators voluntarily include Serbia in broader roaming packages, so check your existing mobile plan before buying another eSIM. If Serbia is already covered at no additional charge, purchasing a separate travel plan may be unnecessary.
If your carrier treats Serbia as an expensive non-EU roaming destination, an eSIM gives you much more predictable costs because the price and data allowance are known in advance.
What About a Balkans Regional eSIM?
A Serbia-specific eSIM usually makes more financial sense if your entire trip takes place inside the country. A regional Balkans plan becomes more interesting if you are combining Serbia with Montenegro, Bosnia and Herzegovina, Albania, North Macedonia or other neighboring destinations.
Nomad, Holafly and other international providers offer regional plans that include Serbia, allowing you to cross borders without installing another eSIM each time. The convenience can justify paying slightly more per gigabyte, particularly on an itinerary where you spend only two or three days in each country.
Check the country list carefully before purchasing. A package labeled “Europe” does not necessarily cover every Western Balkan destination, while regional plans from the same company can have different network partners, data allowances and fair-use conditions.
Tips for Using an eSIM in Serbia
- Download offline maps before a road trip. Serbia has extensive mobile coverage, but mountain roads and sparsely populated regions can still have weaker reception.
- Compare fixed data before buying unlimited. A 10GB or 20GB Nomad package may be substantially cheaper and still cover everything you need during an ordinary holiday.
- Check hotspot rules if you work remotely. Nomad and Saily allow tethering, while Holafly limits sharing on its Serbia unlimited product to 1GB per day.
- Do not assume all unlimited plans are identical. Read the fair-use policy to see whether high-speed data is reduced after a daily threshold.
- Keep your home SIM for verification messages if necessary. Just make sure mobile data and roaming remain disabled on that line unless your home plan includes Serbia.
- Consider a local Serbian eSIM for longer stays. mts and Yettel can provide substantially more data than international eSIM providers at local prices.
- Consider regional coverage before crossing borders. If Serbia is only one stop on a Balkans trip, calculate the cost of one regional eSIM against several separate country plans.

Frequently Asked Questions
What is the best eSIM for Serbia?
For most travelers who want a fixed amount of data, Nomad currently offers the strongest overall value, with 10GB for 30 days at $15 and 20GB for $21. Travelers who want unlimited data should compare Airalo and Holafly, while people staying primarily in Serbia should also look at local mts and Yettel eSIM packages.
What is the cheapest eSIM for Serbia?
Small international eSIM packages currently start at around $4, with Nomad offering 1GB for seven days at $4 and Saily offering 1GB for $3.99. The cheapest option overall depends on how much data you need, because Serbian local eSIMs provide much larger allowances at local prices.
Does Serbia have 5G?
Yes. Commercial 5G became available after Telekom Srbija, Yettel and A1 received spectrum licenses in December 2025, and Serbia had more than 2,300 active 5G base stations by August 2026. Actual 5G availability still depends on your location, phone and eSIM network partner.
How much data do I need for one week in Serbia?
Around 3–5GB is usually enough for maps, messaging, browsing and moderate social media use during a week. Travelers who frequently upload photos and videos, stream content or use hotspot tethering should consider at least 10GB.
Can I keep my normal SIM while using an eSIM in Serbia?
Yes, on most modern dual-SIM phones. You can normally use the Serbia eSIM for mobile data while keeping your regular number active for calls, texts and verification messages. Disable data roaming on your home line if Serbia is not included in your normal plan.
Is Nomad or Airalo better for Serbia?
Nomad currently offers better value on several fixed-data packages and advertises access to multiple Serbian networks depending on the plan. Airalo offers a broader combination of fixed and unlimited packages and may be preferable if you already use its app or want a specific validity period.
Is Holafly worth it in Serbia?
Holafly makes the most sense for travelers who specifically want unlimited data and value access to A1, Yettel and Telekom Srbija rather than relying on a single local network. For moderate data consumption, a fixed package from Nomad or Saily is usually considerably cheaper.
Can tourists buy a Serbian eSIM?
Yes. Local operators now offer eSIM products that tourists can use. mts sells its Tourist and Super Tourist packages with an eSIM option, while Yettel also allows its tourist internet package to be purchased digitally as an eSIM.
Should I buy a local SIM or travel eSIM in Serbia?
An international travel eSIM is usually easier for a short trip because you can install it before departure and start using data immediately after arrival. A local Serbian eSIM is often better value for longer stays or heavy data consumption, particularly because mts and Yettel offer much larger allowances than most international providers.
Which Serbia eSIM Should You Choose?
For a typical trip where 10–20GB is enough, Nomad is currently the strongest overall international choice because its fixed-data pricing is difficult to beat and its Serbia products can provide access to multiple local networks. Saily is a useful alternative for lighter users who value its security features, while Airalo gives you greater flexibility if you want to choose between fixed and unlimited plans.
Holafly remains the premium unlimited option, particularly for travelers who value the possibility of connecting through all three major Serbian operators, although it costs considerably more than a fixed-data plan and limits hotspot sharing.
For longer stays, remote work or anyone who consumes very large amounts of mobile data, the comparison changes completely. Serbia’s local mts and Yettel eSIMs offer much larger data allowances at local prices, and the mts Super Tourist package in particular can make an international unlimited travel eSIM difficult to justify if Serbia is the only country you are visiting.
The best eSIM for Serbia is therefore not one universal product: choose Nomad for fixed-data value, Saily for light usage and security features, Airalo for plan flexibility, Holafly for unlimited multi-network access, and a local mts or Yettel eSIM when maximum data for the lowest local price matters more than the convenience of using an international travel app.
