Yettel is the local SIM most travelers should reach for in Hungary, because it topped the national regulator's speed testing by a wide margin and sells cheap short starter bundles, like 10 GB for five days at around 3,000 HUF, that suit a city break perfectly. Magyar Telekom is the pick if you want sheer volume, with visitor Travel SIMs offering 20 GB for ten days or 100 GB for thirty days, while One (the former Vodafone Hungary) is a solid third. The real friction is the same for all three: Hungarian prepaid lines must be registered against your passport at purchase, and airport stock is unreliable. That is why many visitors skip the shop entirely, and because Hungary is in the EU, an EU-roaming eSIM covers the whole trip.

How Hungary's Networks Actually Differ
Hungary runs on three operators: Yettel (the former Telenor), Magyar Telekom (part of Deutsche Telekom), and One (what Vodafone Hungary became after its early-2025 rebrand). All three advertise nationwide 4G and 5G in the cities, and in Budapest you genuinely cannot go wrong. The differences show up in raw speed and in how each carrier prices its tourist data.
Yettel is the clear speed leader: in the National Media and Infocommunications Authority testing it posted a Speed Score more than double Magyar Telekom's, with average 5G downloads near 280 Mbps, and it hands 5G to every customer at no extra charge. Magyar Telekom runs the most extensive and dependable network overall, with strong rural reach and the 5G build-out inside the Budapest metro to its name, though it reserves 5G for pricier plans. One covers roughly 98 percent of the population and is perfectly reliable, if a step behind on speed. For a traveler, all three are more than fast enough for maps, messaging, and video calls anywhere you are likely to go.
The Registration Rule Tourists Hit
Hungarian prepaid SIMs must be registered to an identity at purchase, so staff will ask for your passport. The process is quick at a staffed carrier store but can be awkward at a busy newsstand, and it is a legal requirement rather than a formality you can skip. A travel eSIM sidesteps registration entirely, which is a big part of why so many visitors choose one.

Yettel: The Speed Leader with Cheap Short Bundles
Hungary's fastest network and the best-value starter packs for a city break
If you are buying one local SIM for a trip centered on Budapest, make it Yettel. It won Hungary's fastest-network title in the regulator's measurements, it switches 5G on for all customers at no surcharge, and its short starter bundles are ideal for the way most people actually visit: a few days of maps, transit tickets, and photos rather than a month of heavy streaming. The 10 GB for five days pack at around 3,000 HUF is hard to beat for a long weekend.
Yettel is also the network most Hungary travel eSIMs quietly ride, so if you go the eSIM route you are very likely on Yettel already without visiting a shop. You can top up at Yettel stores, partner outlets, and online. The catch is the universal one here: the line must be registered to your passport, so buy at a staffed store rather than a rushed newsstand.

Magyar Telekom: Widest Reach and the Biggest Data Buckets
The most extensive network, with visitor Travel SIMs built for volume
Magyar Telekom is the choice when you want a lot of data or you are heading well off the tourist track. Its visitor Travel SIMs are unusually generous, with a 20 GB ten-day option around 10,000 HUF and a 100 GB thirty-day option around 15,000 HUF, which suits a long stay, a remote-working trip, or anyone who tethers a laptop. It also runs the most extensive network in the country, so it holds up best out in the Great Plain, the Bukk hills, and small market towns where the other two thin out.
The trade-offs are that Telekom reserves 5G for its pricier plans, so a budget visitor bundle may stay on 4G, and its short-stay value is weaker than Yettel's cheap five-day packs. For a city-only long weekend, Yettel is the smarter buy; for volume and rural reach, Telekom earns its place.

One
One: The Solid Third Option
The former Vodafone Hungary, dependable but a step behind on speed
One is what Vodafone Hungary became after its rebrand in early 2025, and it remains a perfectly good network, covering roughly 98 percent of the population and running smoothly across Budapest and the main cities. It trails Yettel on measured speed and reserves 5G for higher tiers, so it rarely tops a chart, but for everyday travel data it does the job. Some travel eSIMs, including Holafly and Nomad plans, use One alongside Yettel, so you may end up on it without buying a One SIM at all. As a physical purchase it is a fine fallback if a Yettel or Telekom store is inconvenient, with the same passport registration applying.
Hungary SIM Plans Compared
| Carrier | Sample Plan | Price | Coverage | Best For |
|---|---|---|---|---|
| Yettel | 10 GB, 5 days | ~3,000 HUF (~$8.50) | Fastest in national testing | Short city breaks and speed |
| Yettel | 3 GB, 5 days | ~1,500 HUF (~$4.30) | Fast across Budapest | Light users on a weekend |
| Magyar Telekom | 20 GB, 10 days | ~10,000 HUF (~$28) | Widest rural reach | Longer stays and heavy data |
| Magyar Telekom | 100 GB, 30 days | ~15,000 HUF (~$43) | Broadest network | Remote work and tethering |
| One | Prepaid data add-on | Priced near rivals | Reliable in the cities | A fallback local option |
Prices above reflect typical 2026 rates at roughly 350 forints to the US dollar. Yettel wins on short, fast value, while Telekom's Travel SIMs pack far more gigabytes for a longer trip. Note that none of these local SIMs work once you cross a border, whereas a Europe eSIM keeps running across the EU, which matters on a Central Europe itinerary. Treat this table as your reference before you pay at a counter.
Where to Buy a SIM in Hungary
A Staffed Carrier Store in the City (Best for Registration)
Full Yettel, Magyar Telekom, and One stores across central Budapest, in malls like WestEnd and Arena and on the main shopping streets, are the place to buy. Staff handle the mandatory passport registration on the spot and can set the plan up and test it before you leave. This is the smoothest way to get a working local line.
Budapest Airport (Terminal 2)
You can sometimes buy a prepaid SIM from a shop in the Skycourt or arrivals area at Ferenc Liszt Airport, but hours and stock are inconsistent, prices skew higher, and a late arrival may find nothing open. If you want to be connected the second you land, an eSIM installed before departure is the reliable option.
Newsstands and Convenience Shops for Top-Ups
Once your line is active, tobacconists, newsstands, and supermarkets across the city sell top-up credit and vouchers, and you can recharge in the carrier app. This is the easy way to add data mid-trip without hunting down a flagship store.
Test the Data Before You Leave the Counter
Whichever store you use, put the SIM in and load a map or a website before you walk out. Confirm the data amount and validity match what you paid, and keep the receipt. A minute of checking beats discovering a dead line on the tram an hour later.
eSIM or Local SIM for Hungary?
| Factor | Travel eSIM | Local SIM |
|---|---|---|
| Setup time | A few minutes, done before your flight | 10 to 20 minutes at a store, plus passport registration |
| Registration | None | Passport required by law at purchase |
| Network | Yettel (Airalo) or Yettel and One (Holafly, Nomad) | Any of the three, chosen at the counter |
| Cross-border use | A Europe plan roams the whole EU with no surcharge | Stops working once you leave Hungary |
| Best for | City breaks and multi-country trips wanting zero hassle | Long stays, huge data buckets, or a Hungarian number |
For a trip built around Budapest, with maybe a day trip to the Danube Bend or Balaton, a travel eSIM is the easier call: install it before you fly, land connected, and skip the passport-registration step at a counter. The case for a local SIM is narrower, but real: Magyar Telekom's 100 GB Travel SIM is genuinely good value for a long or data-heavy stay, and only a local SIM gives you a Hungarian number. Where the eSIM pulls ahead decisively is a multi-country itinerary, because a Europe plan keeps working across Vienna, Bratislava, and the Croatian coast on one profile under EU roaming, while a Hungarian SIM stops at the border.
Hungary Connectivity Tips
Practical Advice for Staying Online in Hungary
Choose Yettel for speed, Telekom for volume: Yettel won the national speed testing and sells cheap five-day bundles for a city break, while Magyar Telekom's Travel SIMs pack 20 GB or 100 GB for a longer or data-heavy stay.
Bring your passport: Every Hungarian prepaid SIM must be registered to your identity at purchase. A staffed carrier store handles this in minutes; a busy newsstand may not want to.
Lean on EU roaming: Because Hungary is in the EU, a Europe eSIM covers the whole trip with no surcharge, so if your route continues to Vienna or Croatia you do not need a new plan at each border.
Your data works underground: All four Budapest metro lines carry signal in the tunnels, so you can navigate and buy tickets in the BudapestGO app on the move without station WiFi.
Top up anywhere: Once a line is active, tobacconists, newsstands, and supermarkets sell recharge credit, so adding data mid-trip is quick and everywhere.
Frequently Asked Questions
Do I need my passport to buy a prepaid SIM in Hungary?
Yes. Hungarian law requires every prepaid SIM to be registered to an identity at purchase, so all three carriers will ask for your passport. The process is quick at a staffed Yettel, Magyar Telekom, or One store, but a busy newsstand may be reluctant to handle it. A travel eSIM avoids registration completely, which is one reason many visitors skip the local SIM, especially for a short trip.
Which Hungarian network is best for a tourist?
For most visitors, Yettel. It topped the national regulator's speed testing by a wide margin, includes 5G for all customers, and sells cheap short starter bundles like 10 GB for five days around 3,000 HUF that suit a city break. Choose Magyar Telekom instead if you want a very large data bucket or the widest rural coverage, since its Travel SIMs offer up to 100 GB. One is a dependable third option but a step behind on speed.
How much does a tourist data plan cost in forint right now?
Yettel sells 3 GB for five days around 1,500 HUF and 10 GB for five days around 3,000 HUF, while Magyar Telekom's visitor Travel SIMs run about 10,000 HUF for 20 GB over ten days and about 15,000 HUF for 100 GB over thirty days. At roughly 350 forints to the US dollar in 2026, that puts a short Yettel pack near 8 dollars and Telekom's big bucket near 43 dollars. Add a starter SIM fee of a few hundred forint on top.
Can I buy a Hungarian SIM the minute I land at Budapest Airport?
Sometimes, but it is not reliable. Ferenc Liszt has a single terminal and no dedicated carrier desks, so you would be looking for a prepaid SIM at a newsstand or convenience shop in the Skycourt or arrivals area, where hours and stock vary and prices run higher. A late-night arrival may find nothing open. If you want to be online the moment you land, an eSIM installed before departure is the dependable choice.
For a week in Budapest, should I get a local SIM or an eSIM?
For a week centered on Budapest with a day trip or two, an eSIM is usually easier: it installs before you fly, connects on arrival, and skips passport registration. A local SIM earns its place mainly for a long or very data-heavy stay, where Magyar Telekom's 100 GB Travel SIM is strong value, or if you specifically need a Hungarian number. And if your trip crosses into Austria or Croatia, a Europe eSIM covers all of it on one plan while a Hungarian SIM would stop at the border.
