The Hungary SIM Card Guide: Most Visitors Should Buy Nothing

If you are flying in from anywhere in the EU, the correct amount to spend on a Hungarian SIM card is zero forints. Your own plan already works here at your domestic price, and the only useful thing you can do before the flight is check one number buried in your contract.

Everyone else, and since Brexit that includes the UK, has a real decision to make. Here is the short version, with the prices the operators actually publish and the one legal rule that catches visitors out at the counter.

EU and EEA Visitors Already Have This Covered

Regulation (EU) 2022/612, the “roam like at home” rule, means an EU or EEA subscriber uses their domestic allowance in Hungary with no surcharge. Not a discount, not a bundle you activate. Your minutes, your texts, your data, at your home price, on the same network quality and speed you get at home.

It covers all EU member states plus Iceland, Liechtenstein and Norway, and has since been extended to Moldova and Ukraine. The regulation runs until 30 June 2032, so this is not a temporary arrangement anyone needs to plan around.

Which means that for a large share of visitors, the entire SIM card question resolves to: land, turn the phone on, carry on.

The One Number Worth Checking Before You Fly

Fair use is where unlimited quietly stops being unlimited.

On an unlimited-data plan, your operator may cap your roaming data at twice the monthly plan price divided by 1.30 euros. A 30 euro unlimited plan therefore gives you roughly 46 GB abroad before the throttling or the surcharges start. On prepaid, the formula uses your remaining credit instead: credit divided by 1.30 euros.

The wholesale ceiling behind that divisor drops from 1.30 euros per GB to 1.00 euro per GB from 2027, which pushes those caps up. Until then, 1.30 is the number to do the arithmetic with.

This is the thing to look up, not the border. Nobody stops you at passport control to ask about your data plan, but a five-day trip that streams two films a night can absolutely find the edge of a fair-use cap on a cheap plan.

UK Visitors: Brexit Put You Back in the Queue

The UK sits outside the EU roaming regime, and each UK operator now sets its own policy for European travel. Some charge, some do not, and the terms differ enough that the only reliable source is your own contract.

If yours bills you for Hungary, read on: everything below applies to you exactly as it applies to a visitor arriving from outside Europe.

Who Actually Sells SIM Cards in Hungary Now

Three networks. Two of them changed names recently enough that half the internet has not noticed.

Operator today	Previously	Prepaid brands	Scale
Magyar Telekom	unchanged	Domino, Travel SIM	Largest, roughly 44 to 45% of the mobile market
Yettel Hungary	Telenor Hungary, rebranded 2022	Yettel prepaid, visitor eSIM	Roughly 25 to 26%
One Hungary	Vodafone Hungary and DIGI, both bought by 4iG, unified under One in early 2025	One Instant, Tuti	Around 3 million mobile customers

Telenor and Vodafone no longer exist as Hungarian brands. This is genuinely useful to know as a reader, because it dates a guide instantly. If a page tells you to walk into a Vodafone shop in Budapest, it is describing a market that closed, and whatever it says about prices is from the same vintage.

You Cannot Buy a SIM Here Without ID

This is the part several travel blogs get wrong, and getting it wrong costs you an afternoon.

Identity verification is mandatory before a Hungarian mobile contract is concluded, prepaid included. The regulator, NMHH, puts it plainly: without a successful check, the contract cannot be concluded and the service cannot be started. There is no anonymous SIM on a Hungarian shelf.

What counts as ID: a Hungarian identity card, a temporary identity card, a passport, or a driving licence. If you hold no Hungarian documents, you present a document or permit authorising your entry to or residence in Hungary, and you present it in person.

Two things follow from that:

1. Foreigners buy in person. All three operators say so, and non-EEA citizens need a passport specifically.
2. Verification repeats annually. A prepaid card that is not re-verified gets switched off. Irrelevant on a week’s holiday, but it explains why a spare Hungarian SIM someone hands you from a drawer is often already dead.

The exception, and it is the whole reason for the recommendation further down: Yettel sells a visitor eSIM online, with no store visit.

Yettel: The Only One You Can Buy Before You Land

The visitor eSIM arrives as a QR code, activates the first time your phone connects to a Hungarian network, and has to be activated within 30 days of purchase. Roaming on these passes covers the EU plus Iceland, Norway and the UK, so a Budapest-then-Vienna trip stays on one product.

The same price points exist as physical SIMs in store, which is the route to take if your phone does not do eSIM. Central Budapest branches sit at Astoria, WestEnd and Corvin Mall.

Telekom: The Airport Counter

The Travel SIM is sold only to holders of a non-Hungarian identity document, and only to over-18s. Two catches worth knowing before you hand over 10,000 Ft: it is non-rechargeable, so when the data runs out the SIM is finished rather than topped up, and unused data disappears at expiry rather than rolling over.

There is an eSIM version of it, but that one has to be bought in a store, which removes most of the reason to want an eSIM.

Telekom runs the counter at Budapest Airport, Terminal 2B, Arrivals, landside, which is past baggage reclaim and before you leave the building. That makes it the default for anyone who decided nothing in advance. If you are still working out the rest of the arrival, our Budapest Airport guide and the route into the city cover what comes after the counter.

One: Cheapest Plastic, Most Legwork

The SIM itself is the cheapest on the market at 500 Ft online or 1,500 Ft in store. The Tuti tariff carries no monthly fee, charges 19 Ft per minute for calls, and comes with a starter allowance of 2 GB and 100 minutes for 30 days. Data top-ups run 2,290 Ft for 5 GB and 4,990 Ft for 20 GB, both valid 30 days.

One Instant starter kits turn up at fuel stations and hypermarkets, which is convenient right up until the identity check. English-language phone support is on 1270, option 8.

This is the option for someone staying long enough that the per-gigabyte cost matters. For three days in Budapest, the errand is worth more than the saving.

Where to Buy One

• Budapest Airport: the Telekom counter in Terminal 2B, Arrivals, landside.
• Operator stores: all three, and the required route for a foreigner buying a physical SIM.
• Post offices: Magyar Posta counters carry all three brands.
• Fuel stations and hypermarkets: One Instant kits.
• Wolt: Yettel prepaid gets couriered to you.
• Online, in a form that works for a visitor: Yettel’s visitor eSIM, and nothing else.

The trap. Buying the card at a post office or off a supermarket shelf does not exempt you from the ID rule. The plastic is sold there; the identity check still has to happen before the number works, and for a foreigner that generally means walking into an operator store afterwards anyway. A pack in your hand is not a working phone number.

Travel eSIM Apps

The international travel eSIM providers sell Hungary packages too. What you get is a roaming guest slot on a host network rather than a Hungarian contract, which is why they skip the ID desk entirely. You give up the local number, and you are a lower-priority customer on whichever network hosts you. Worth comparing if Hungary is one stop on a multi-country trip. Not the better answer if Budapest is the whole holiday, where a Yettel pass costs about the same and puts you on the network directly.

The WiFi Reality

Budapest Airport runs free WiFi under the SSID bud:free wifi, across Terminal 2A, Terminal 2B and SkyCourt. It wants an email address, then gives you four-hour sessions that you reconnect for another four.

In the city, coverage is good where you would expect it: cafes, hotels, shopping centres, and the Szabó Ervin library network. What does not exist is a city-wide municipal network, and there is no WiFi on the BKK metro. Budapest is a city where you need data in your pocket, not a city you can navigate hopping between hotspots, and the metro is exactly where a live connection matters, because the BudapestGO ticketing app wants one to display a validated ticket underground.

What to Buy, in One Line

Yettel Pass S: 5,000 Ft, three days of unlimited data, bought online as an eSIM before you land. It is the only option that puts you on a Hungarian network, skips both the store queue and the in-person identity check, and publishes its price on the operator’s own site. Staying a week, Pass M at 9,000 Ft. Staying a month and moving around the region, Pass L at 12,000 Ft.

And if you are arriving from Vienna, Kraków or Berlin: close this tab, check your fair-use cap, and spend the 5,000 Ft on lunch instead. Once your phone works, the rest of the toolkit is small, and our guide to the travel apps worth installing for Hungary covers what to put on it. For the other half of arrival admin, where to change money without getting fleeced is the companion piece.
