What is an eSIM, and how does it work in Serbia?
An eSIM (embedded SIM) is a digital SIM card built into your phone or device, eliminating the need for a physical SIM card. Instead of inserting a traditional SIM, you download a digital profile from your provider, which allows you to connect to local mobile networks.
In Serbia, eSIMs work just like physical SIM cards, but with more flexibility. Once you install the eSIM profile, your device connects to local Serbian networks like Yettel (used by Ubigi) or A1 (used by eSIM4Travel). These networks provide 4G/LTE or 5G coverage in major cities like Belgrade and Novi Sad, as well as throughout rural areas. The eSIM automatically connects to the best available network when you arrive in Serbia, ensuring you stay online without having to visit a local store or change physical SIM cards.
With an eSIM, you can also store multiple profiles, making it easy to switch between networks or plans if needed, offering a seamless experience for short-term visitors or long-term digital nomads in Serbia.
What’s better for Serbia: an eSIM or a local SIM card?
For most travelers, an eSIM is better than buying a local SIM card in Serbia. It’s quicker to set up, doesn’t require a store visit, and avoids the hassle of registration or providing ID.
With an eSIM, you can download and activate your plan before departure, connecting instantly once you arrive in Serbia. This is especially handy for remote workers, short stays, or when arriving late at night. Local SIM cards, on the other hand, often require in-person activation and can be more expensive for short-term use.
Why eSIMs are better for Serbia:
✅ Instant activation via QR code or app
✅ Access to reliable networks like Yettel (Ubigi) and A1 (eSIM4Travel)
✅ No need for local ID or passport registration
✅ Easy to manage multiple plans and top-ups
✅ Works across major cities like Belgrade, Novi Sad, and rural areas
In short, eSIMs offer flexibility, convenience, and hassle-free connectivity, while local SIM cards are better suited for long-term stays requiring a Serbian phone number.

How to choose the right eSIM for Serbia
Choosing the best eSIM for Serbia depends on your data needs and travel plans. Here are a few quick tips to help you decide:
- Check your data needs: For light use like browsing and messaging, a smaller plan (1GB to 3GB) is usually enough. For streaming, video calls, or remote work, go for a larger plan (10GB+).
- Consider your trip length: Short stays are better suited for smaller plans, while longer trips benefit from fixed-duration or unlimited plans.
- Ensure compatibility: Most modern phones support eSIM, but it’s always best to check your device settings first.
- Review coverage: Think about where you’ll be. If you’re staying in major cities like Belgrade or Novi Sad, most plans will work well. For rural areas, consider a plan with solid network coverage.
