Serbia eSIM for Travel – Instant 4G/5G Data
Instant mobile data in Serbia from £4.99. No roaming charges. Keep your UK number. Activates the moment you land.
Serbia is outside the EU, so even old UK roaming plans charge extra – yet Belgrade has become one of Europe's best nightlife and food cities. TripSIM provides an instant Serbia eSIM with coverage on Telekom Srbija (mts), Yettel Serbia, A1 Serbia, so you can land at Belgrade Nikola Tesla (BEG) and be online before you reach the taxi rank. Wizz Air and Ryanair fly direct from Luton to Belgrade. Without EU roaming, UK travellers face full international rates without a TripSIM eSIM. No physical SIM swap, no airport kiosks, no surprises on your next UK phone bill.

Serbia eSIM FAQs
Does an eSIM work in Serbia?
Yes — TripSIM eSIMs work across Serbia on local 4G/5G networks (Telekom Srbija (mts), Yettel Serbia, A1 Serbia). You activate before you fly and it connects automatically when you land.
Can I keep my UK number while using a Serbia eSIM?
Yes. Your physical UK SIM stays active for calls, texts and WhatsApp. The TripSIM eSIM runs alongside it as a data-only line.
Is hotspot / tethering included?
Yes, every TripSIM plan supports personal hotspot.
When should I install the eSIM?
Install before you leave the UK while on WiFi. Activation only starts when you connect to a local network in Serbia.
Is TripSIM cheaper than UK carrier roaming in Serbia?
Almost always. UK carriers typically charge £5–£9 per MB on UK carriers (non-EU) in Serbia. Save up to 88% vs UK roaming.
Will a TripSIM eSIM work across Serbia?
Yes. TripSIM connects to Telekom Srbija (mts), Yettel Serbia, A1 Serbia, which together cover Belgrade, Novi Sad, Niš and most Serbia travel destinations. Coverage in rural areas may be more limited – check the coverage map before travelling off the main routes.
How much data do I need for 3 days in Serbia?
For typical UK-tourist use (maps, messaging, social, occasional video calls), 0.5–1 GB per day is a comfortable allowance. We recommend our mid-tier plans for shorter trips and unlimited for two-week stays.
Is the TripSIM Serbia eSIM faster than buying a SIM at Belgrade airport?
Buying a local SIM in Serbia usually means queueing at an arrivals kiosk, showing your passport, topping up in Serbian Dinar and configuring APN settings. A TripSIM eSIM is QR-activated before you fly and online the moment your phone connects to a Serbia network.
Can I make voice calls or send SMS with a TripSIM Serbia eSIM?
TripSIM is a data-only eSIM. Voice and SMS are not supported – but you can call and message over WhatsApp, FaceTime, Telegram and other internet-based apps as normal. For UK emergency services, your physical SIM remains the appropriate route.
Does the TripSIM Serbia eSIM work alongside my UK SIM?
Yes. Dual-SIM phones (iPhone XS and later, most modern Androids) can run your UK number for calls/SMS and your TripSIM data plan in parallel. We recommend turning off mobile data on your UK SIM to avoid roaming charges.
