What a Serbia Mobile eSIM costs
The cheapest published plan on the Serbia travel eSIM is $4.00 for 1 GB valid 7 days. A 2 GB / 15 day plan is $6.50, a 3 GB / 30 day plan is $7.20, a 5 GB / 30 day plan is $11.00, 10 GB over 30 days is $16.20, and 20 GB over 30 days is $22.95. The 3 GB / 30 day plan is the value pick: a full month for $3.20 more than the 7 day plan. Per gigabyte the buckets improve steadily down to about $1.15 on the 20 GB plan, so heavier use is rewarded here.
Network
The plan is sold under the operator name Serbia Mobile and the supported country is Serbia. The product page publishes the speed as 5G, and real speed still depends on the mast, the handset, and the carrier Fair Usage Policy. Serbia is covered as one country on this plan, with the densest coverage in Belgrade, Novi Sad and Niš, and along the main motorway corridors; expect thinner service in the mountainous south-west and the rural east. Serbia is not in the European Union, so do not assume a home SIM’s EU roaming bundle covers it, and this is not a Balkans regional plan: Bosnia and Herzegovina, Croatia, Hungary, Romania, Bulgaria, North Macedonia and Montenegro each need their own plan. The product page does not publish a coverage map, so treat long rural drives as outside the guarantee.
How much data you actually need
Maps, chat, and bus or train tickets sit inside 1 GB for a short city break. A week moving between Belgrade, Novi Sad and the south with daily photo uploads is the 3 GB or 5 GB plan, and a month of travel or hotspotting is 10 GB or 20 GB. Hotel and cafe Wi-Fi is widely available in Serbian cities, so the larger buckets are mainly about hotspotting and video.
Unlimited data
Unlimited plans are listed on the same product page, from $16.65 for 3 days, $23.38 for 5 days, $28.48 for 7 days, $31.88 for 10 days, $48.00 for 15 days and $80.75 for 30 days. On this product the unlimited tiers are expensive, so do the comparison before you pay: 20 GB over 30 days costs $22.95, which is less than the 5 day unlimited plan, and 10 GB over 30 days at $16.20 is cheaper than 3 days of unlimited at $16.65. Unlimited still sits under a Fair Usage Policy, so a hotspot left running all day is exactly what gets slowed.
Dual SIM
Keep your home SIM for calls and bank texts. Turn on data roaming only for the Serbia Mobile line. iPhone: Settings, Mobile Data, pick the travel line. Android: Settings, Network, SIMs, set mobile data to the travel eSIM. Do this before you leave the airport Wi-Fi.
Arrival and transit
Most visitors land at Belgrade Nikola Tesla Airport (BEG), with Niš Constantine the Great (INI) handling a smaller number of flights and land crossings from Hungary, Croatia, Bosnia and Herzegovina, Montenegro, North Macedonia, Bulgaria and Romania. Install the eSIM on hotel or home Wi-Fi before the flight, then switch the data line on after you clear arrivals. You do not need a local shop or a passport photo for this plan.
Install
- Buy the plan and open the QR code in the order email while you still have Wi-Fi.
- On the phone, add an eSIM and scan that code. Label the line “Serbia”.
- After landing, set mobile data to that line and leave your home number on for texts.
Phone compatibility
The phone must be carrier-unlocked and eSIM-capable. iPhone XS and later, and recent Samsung Galaxy and Google Pixel models, qualify. A locked handset will not take the QR code. Check the lock status with your home carrier before you pay.
FAQ
Q1: How much is the cheapest Serbia eSIM?
$4.00 for 1 GB, valid 7 days, on the Serbia Mobile plan.
Q2: Which operator is on the plan?
Serbia Mobile. The supported country is Serbia.
Q3: Does it include calls and SMS?
No. It is a data plan, with voice calls only through apps such as WhatsApp or FaceTime. Keep your home SIM for calls and one-time passwords.
Q4: Is it 5G?
Yes. The product page lists the speed as 5G. Real speed still depends on coverage and the Fair Usage Policy.
Q5: Can I install it after I land?
Yes, if you can reach Wi-Fi. Installing before the flight is simpler, because the QR download needs a connection.
Q6: Will it work outside Serbia?
No. Serbia is not in the EU and this is not a Balkans regional plan, so the neighbouring countries each need their own plan.
Q7: Is there an unlimited option?
Yes. Unlimited plans are listed separately on the same product page, from $16.65 for 3 days.
Q8: Can I share it as a hotspot?
Yes, within the data allowance. Hotspot traffic counts against the same gigabytes, and heavy sharing can hit the Fair Usage Policy.
Q9: What if the QR code fails?
Use the manual activation code in the same email. The phone still has to be unlocked.
Q10: When were these prices checked?
October 2026, against the published variation prices on travelydata.com.
Bottom line
For a week in Serbia, the $4.00 / 1 GB Serbia Mobile plan is the entry point, and the 3 GB / 30 day plan at $7.20 is the one most travellers should buy because it lasts a full month. A travelling week is 5 GB or 10 GB, a month of heavy use is 20 GB at $22.95, and unlimited starts at $16.65 for 3 days. The published speed is 5G, Serbia is outside the EU, and the buckets beat unlimited here.
