Best eSIM for Serbia: Plans, Prices and Coverage
July 22nd, 2026
TL;DR: The cheapest Keep On Roaming eSIM for Serbia is the Roam Like Home® Serbia 1 GB 7 Days plan at £6.00. If you judge value by price per GB, the 100 GB 30 Days plan is the strongest of the fixed data plans at £64.00, which works out at 64p per GB, while the 20 GB 30 Days plan at £18.50 comes in at under £1 per GB. For short trips where you would rather not count megabytes, unlimited data starts at £8.00 for 1 day. Every plan connects to A1 Srbija, Telekom and Yettel Serbia.
What to look for in a travel eSIM for Serbia
Serbia sits outside the EU, so the roaming rules that keep prices down across much of Europe do not apply here. Turning up with your home SIM and hoping for the best can get expensive quickly, which is why a dedicated travel eSIM is worth sorting out before you go.
When you compare options, four things matter most:
- Coverage. You want an eSIM that connects to Serbia's main mobile networks, not just one of them, so you keep a signal whether you are in Belgrade, Novi Sad or somewhere far quieter.
- Plan flexibility. A weekend city break and a month of working from a rented flat need very different plans. Look for a range of durations and data sizes so you only pay for what you will actually use.
- Top-ups. Trips rarely go exactly to plan. If you burn through your data early, you should be able to add more without starting from scratch.
- Installation before you fly. The best time to set up a travel eSIM is at home on Wi-Fi, not in an arrivals hall hunting for a signal. Install it before you travel and you are connected from the moment you land.

On price per GB, the fixed data plans reward going bigger. The 10 GB 30 Days plan works out at £1.60 per GB, the 20 GB plan drops below £1 per GB at £18.50, and the 100 GB plan is the cheapest per GB of all at 64p. If your trip is a week or less and you stream, video call or hotspot-level browse without thinking about it, compare those against the unlimited options, which run from 1 day at £8.00 up to 30 days at £54.50.
All of these plans connect to Serbia's three main networks: A1 Srbija, Telekom and Yettel Serbia. Each supports 2G, 3G and 4G, so your phone can pick the strongest available signal as you move around the country.
Frequently asked questions
Will my phone work with an eSIM?
Most recent smartphones support eSIM, but it is worth checking before you buy. Look in your phone's mobile network settings for an option to add an eSIM or a data plan. Your phone also needs to be unlocked by your home carrier, so if you bought it on a contract, confirm that first.
When should I install my eSIM?
Before you fly. Installing at home on a reliable Wi-Fi connection means you can take your time, and your Serbian data is ready the moment you land. Leaving it until you arrive means relying on airport Wi-Fi at the exact moment you least want to.
What happens if I use up my data?
You can top up. If your fixed data plan runs dry mid-trip, add more data rather than going without or falling back on expensive roaming. If you regularly find yourself topping up, an unlimited plan may suit your next trip better.
Will my phone number change?
No. A travel eSIM provides data, and your existing number stays with your usual SIM, which can remain active in your phone at the same time. Just make sure data roaming is switched off on your home line so it cannot quietly rack up charges, and route your data through the eSIM instead.
What network speeds will I get in Serbia?
The plans connect over 2G, 3G and 4G on A1 Srbija, Telekom and Yettel Serbia. In practice your phone will use 4G wherever it is available, which covers everyday travel needs like maps, messaging, video calls and streaming.
