Pros and cons
Pros
- It is a network seller, network, so plans come straight from the host network rather than a reseller.
- Sim only lines are available, so you can keep the handset you already own.
- Unlimited data starts at RSD 1,999 on NEO Surf, and NEO Super raises the full speed allowance at a higher monthly figure.
- 5G and eSIM are both supported, and hotspot sharing is included.
- EU roaming runs on a fair use basis across 49 countries, which suits regular travellers.
Cons
- Data rollover is a no, so unused data is lost each month.
- Billing covers contract and prepaid, with no rolling monthly option.
- Klasik pairs a small data allowance with a 24-month term.
- EU roaming runs on fair use, not on fully included terms.
Who it suits
- People in Serbia who want a contract line from the host network itself, with 5G and eSIM included.
- Households that want unlimited data for a single monthly figure, starting at RSD 1,999.
- Travellers who need EU roaming on a fair use basis across 49 countries.
Who should look elsewhere
- Anyone who wants unused data to roll into the next month, since data rollover is a no.
- People who want a rolling monthly deal without a contract, since billing covers contract and prepaid.
- Buyers comparing sellers outside Serbia, since the service runs in RS only.
Pricing
Prices are quoted monthly, and the entry figure of RSD 1,199 belongs to the Klasik plan. Klasik carries a small data allowance and runs for 24 months, so the low number comes with both a light allowance and a long commitment. Two steps sit above it: NEO Surf, at the unlimited price of RSD 1,999, adds a larger full speed data block plus unlimited usage, and NEO Super adds more full speed data again for a higher monthly figure. In other words, RSD 1,199 is the cheapest way in and RSD 1,999 is the point at which data stops being the limit, rather than the cost of the cheapest line. Billing runs through contract and prepaid, so a prepaid option sits alongside the contract plans, though the Klasik, NEO Surf and NEO Super prices above are the contract side of the range.
What it does well
Sim only lines are available, which is the practical route in if you already have a handset you like. 5G is supported, and an eSIM is offered, so a new line can be set up without waiting for a plastic card. Hotspot sharing is included, so the same allowance can serve a laptop or tablet. EU roaming runs on a fair use basis, covering 49 countries, which matters for anyone crossing borders regularly on the same number. The one clear gap is data rollover: it is a no, so whatever data is left at the end of a month is lost rather than carried forward. Taken together, the feature set is strong on network capability and connectivity options, and thin on giving you flexibility with unused data.
Who runs it
A1 Serbia sells as a network rather than a reseller or a mobile virtual network operator, so the plans sit on the host's own infrastructure. The legal entity behind the service is A1 Srbija d.o.o. Beograd, and the headquarters are in Serbia. Support runs through phone, email and help centre, which means you can reach the provider by phone, by email, through the help centre or by chat. The service is offered in Serbia, so the plans are aimed at the Serbian market specifically, and the same support channels come from the company itself rather than a third party desk.

Frequently asked questions
How much does A1 Serbia cost to start?+
The entry price is RSD 1,199 a month, and that figure belongs to the Klasik plan. Klasik comes with a small data allowance and runs for 24 months, so the low entry price is paired with both a light allowance and a long term. If you want more data, the next plan, NEO Surf, is priced at RSD 1,999.
What does unlimited data cost on A1 Serbia?+
Unlimited data starts at RSD 1,999 a month on the NEO Surf plan, which pairs a large full speed block with unlimited usage. A step higher, NEO Super, adds more full speed data for a higher monthly figure. So RSD 1,999 is the point where data stops being the limit on the line.
Can I get a SIM only line from A1 Serbia?+
Yes, sim only is offered, so you can take a contract line and keep the handset you already have. Billing runs through contract and prepaid, which covers contract and prepaid, so there is flexibility on how the line is billed. A1 Serbia is a network seller, network, so the plan runs on its own network.
How long is the contract on A1 Serbia plans?+
The plan contract runs for 24 months, and that term applies to the Klasik, NEO Surf and NEO Super plans described here. That is a long initial commitment, so the monthly figures stay low but the line is tied in. If you would rather not commit, the prepaid side of contract and prepaid is the looser option.
Does A1 Serbia include roaming in the EU?+
Roaming in the EU runs on a fair use basis and covers 49 countries, rather than being fully included without limits. For the occasional trip that is usually enough. Frequent heavy use abroad is the case where a fair use basis can start to matter, so it is worth checking before a long stay.
Can I get an eSIM and 5G from A1 Serbia?+
Both are supported: 5G is available and an eSIM is offered alongside physical SIM options. Hotspot sharing is included too, so the same data allowance can serve a laptop or tablet. The one feature that is a no is data rollover, so unused data from a month does not carry into the next.
Who runs A1 Serbia and how do I get help?+
A1 Serbia sells as a network, network, with the legal entity A1 Srbija d.o.o. Beograd and headquarters in Serbia. Support runs through phone, email and help centre, so you can reach the provider by phone, by email, through the help centre or by chat. The service is offered in Serbia.
What is the catch with the cheapest plan?+
The cheapest figure of RSD 1,199 a month sits on the Klasik plan, which pairs a small data allowance with a 24-month term. You are also giving up rollover, since data rollover is a no across the range. Anyone who regularly uses a lot of data will outgrow it and pay more on NEO Surf at RSD 1,999.
