Sorting out a Budapest SIM card (or, increasingly, an eSIM) is one of the easiest things to tick off before or during your trip, but a little planning saves you money and hassle. The short version: if your phone supports eSIM, an eSIM is the simplest option, you can buy and activate one online before you even land. If you prefer a physical SIM or want a local number, Hungary’s three carriers (Telekom, Yettel and Vodafone) all sell cheap prepaid tourist packages from their downtown stores. Whatever you do, do not buy your SIM at the airport, where prices are inflated. This guide covers every option, current 2026 prices, and how to choose.
Staying connected makes navigating, booking and translating far easier. Pair this with our Budapest travel tips and the broader Budapest travel guide.
Do you even need a SIM?
First, a money-saving question. If you are visiting from elsewhere in the European Union, your home plan almost certainly includes “roam like at home” in Hungary at no extra cost, so you may not need anything at all, just check your allowance. If you are coming from the UK, the US, or further afield, roaming charges can be brutal, and a local SIM or eSIM will save you a fortune versus your home carrier’s roaming rates. Budapest also has generous free Wi-Fi (see below), so very light users can sometimes get by on that alone. For everyone else, a cheap local data plan is well worth it.
eSIM vs physical SIM
The big shift in recent years is the eSIM, a digital SIM you install by scanning a QR code, with no plastic to swap. If your phone supports it (most recent iPhones and flagship Androids do), an eSIM is genuinely the easiest route: buy online, install before you fly, and connect the moment you land, keeping your home SIM active for calls and texts. A physical SIM still makes sense if your phone is older or eSIM-incompatible, if you want a local Hungarian phone number, or if you simply prefer buying in person. Both are cheap in Hungary.
The three Hungarian carriers
Hungary has three main mobile networks, all with good coverage in Budapest and solid nationwide reach: Magyar Telekom (generally the widest coverage), Yettel (formerly Telenor), and Vodafone. All three now offer both prepaid physical SIMs and tourist eSIMs. You will find their stores in the city centre and in shopping malls; bring your passport, as registration of prepaid SIMs is required by law.
Prepaid prices in 2026
| Option | Approx. 2026 price | Notes |
|---|---|---|
| Yettel data-only (5 GB) | ~3,300 HUF | Cheap, data only, no calls |
| Yettel small bundles | 1 GB ~1,100 HUF / 3 GB ~2,500 HUF | Top up as needed |
| Telekom Tourist SIM (10–30 GB) | ~5,500–10,000 HUF | 30-day validity, good for heavy use |
| Vodafone tourist eSIM (unlimited*) | ~11,990 HUF | Unlimited HU + 30 GB EU + calls/SMS |
| International eSIM (Airalo etc.) | from ~$4–5 per GB | Buy online before you arrive |
Best eSIM options
For convenience, an international travel eSIM (providers like Airalo, Holafly, aloSIM and others) is hard to beat: you buy a Hungary or Europe plan online, install it before you travel, and you are connected on arrival, with plans starting from just a few dollars per gigabyte. The trade-off is they are data-only (no local number) and sometimes a touch pricier per GB than a local prepaid for heavy users. If you want maximum convenience and only need data for maps, messaging and browsing, an eSIM is the move. If you need lots of data or a local number, a carrier prepaid SIM may work out cheaper.
Where to buy (and where not to)
The single most important tip: do not buy a SIM at Budapest Airport. The airport kiosks sell overpriced physical SIMs and you cannot buy a proper local eSIM there anyway. Instead, either sort an eSIM online before you fly, or buy a prepaid SIM at an official Telekom, Yettel or Vodafone store in the city centre, where prices are far better and staff can set it up for you. There are branches around the main shopping streets and in malls like WestEnd and Aréna.
Coverage and network speed
You will have little to complain about on the network front. All three Hungarian carriers offer fast 4G/LTE across Budapest and 5G in much of the city, with strong coverage throughout the metro (yes, even underground), on trams and in the baths. Telekom generally has the widest rural reach if you are heading out on day trips to the Danube Bend, Eger or Lake Balaton, but all three are perfectly solid for a city break. International eSIMs piggyback on these same local networks, so speeds are comparable. In practice, you can expect reliable, quick data almost everywhere a visitor goes.
Calling and texting home
If you only buy a data eSIM, you will not have a local phone number, but that is rarely a problem for travellers. You can call and message over the internet using WhatsApp, Messenger, FaceTime, Telegram or similar, which is how most people stay in touch anyway, and you keep your home SIM active (for the odd verification text) while using the travel eSIM for data. If you specifically need a Hungarian number, for example to receive local booking confirmations, choose a carrier prepaid SIM rather than a data-only eSIM.
How much data do you need?
For a typical city break, lots of maps, messaging, social media and the odd video, 5–10 GB comfortably covers a week. If you stream a lot or tether other devices, go for 20–30 GB or an unlimited plan. Light users who mostly rely on Wi-Fi and just want maps and messaging on the go can manage with 3–5 GB. When in doubt, a 10 GB plan is the sweet spot for most visitors.
Free Wi-Fi in Budapest
Budapest is well covered for free Wi-Fi. Most hotels, cafés, restaurants and bars offer it, the public transport system and many public spaces have hotspots, and you will find connectivity at the airport and major attractions. Light users can lean on this, but for live navigation, ride-hailing and translation while you are out and about, a cheap data plan is far more convenient than hunting for a signal.
Setting up your eSIM
Installing an eSIM takes a couple of minutes. After buying, you receive a QR code; on an iPhone go to Settings, Cellular, Add eSIM, and scan it (Android is similar under network settings). Do this on Wi-Fi before you travel, then enable data roaming for the travel eSIM once you land and set it as your data line, keeping your home SIM for calls. Label your lines so you do not accidentally rack up home-roaming charges. If in doubt, the provider’s app walks you through it.
Longer stays and families
If you are staying a month or more, a carrier prepaid SIM with a monthly bundle usually beats stacking short travel-eSIM plans on cost. For families or groups, one option is to buy a larger data plan on one phone and share it via a personal hotspot, cheaper than buying a plan for everyone, provided your plan allows tethering (most do). Digital nomads working from Budapest will want one of the larger 20–30 GB or unlimited monthly bundles for comfort.
Common mistakes to avoid
- Buying at the airport. Overpriced physical SIMs and no proper local eSIM, sort it in town or online instead.
- Forgetting your passport. You cannot register a prepaid SIM without ID.
- Leaving home data roaming on by accident. Disable it on your home SIM so you are not charged while using the travel eSIM.
- Overbuying data. Most visitors comfortably manage on 5–10 GB for a week thanks to widespread Wi-Fi.
- Assuming you need anything at all. EU visitors usually roam free, check first.
Practical tips
- Bring your passport, prepaid SIM registration is legally required in Hungary.
- Sort an eSIM before you fly so you land connected.
- Skip the airport SIM kiosks, buy in the city or online.
- Check whether your EU home plan already covers Hungary for free.
- Keep your home SIM for calls/texts and use the travel eSIM for data.
- Top up online or in-store if you run low, it is easy.
