The currency is the Hungarian forint

Hungary uses the Hungarian forint (HUF), not the euro. Some visitor-facing businesses may quote or accept euros, but that does not make the euro the local currency. For normal spending, think in forint and check the HUF total before paying.

This matters most at card terminals and ATMs. If a machine asks whether you want to be charged in your home currency instead of HUF, that is a currency-conversion offer rather than a convenience you must accept. The Hungarian National Bank advises card users to pay attention to exchange rates and costs when using cards abroad; in practical travel terms, compare the offer and avoid blindly accepting a merchant or ATM conversion.

Cards versus cash

A card can cover most everyday visitor spending: hotels, supermarkets, attraction tickets, restaurants and many cafés. Still, carry a modest amount of forint for small purchases, market stalls or the occasional cash-only situation. You do not need to withdraw a large amount on day one.

Before travelling, check your own bank's foreign transaction and cash-withdrawal fees. A "fee-free" ATM does not mean your home bank will also charge nothing.

Using ATMs safely

Prefer a cash machine attached to a real bank branch when that is practical. Read each screen instead of rushing, decline unsolicited help from strangers and collect your card and cash before stepping away. Budapest Police has warned specifically about thieves approaching foreign visitors at ATMs in the central party district, so treat anyone offering to "fix" the machine or change its language as a reason to end the transaction.

If the ATM offers its own currency conversion, look for the option that keeps the withdrawal in HUF rather than automatically converting it to your home currency. The final cost also depends on your own bank and card.

Roaming may already be enough

If your existing mobile plan includes Hungary under EU/EEA roaming, keeping your home SIM may be the easiest option. Check your provider's fair-use limits before you leave, especially if you plan to tether a laptop or use large amounts of video data.

For visitors whose home plan makes roaming expensive, Hungary's networks now market short-stay options directly to travellers, so there is no need to depend on an anonymous third-party kiosk.

Tourist eSIM options

Yettel currently advertises prepaid tourist eSIM plans that can be bought before travel and activated from a QR code on a compatible device. That is useful if you want data ready without visiting a shop after landing.

Magyar Telekom advertises a Travel SIM that is also available as an eSIM; its current visitor page says you purchase the Travel SIM/eSIM in a Telekom store. One has visitor support in English and says non-Hungarian customers activating its pay-as-you-go product should visit a One store with accepted identification.

Products, prices and data allowances change, so use the operators' current visitor pages when you are ready to buy rather than copying an old package from a blog.

Physical SIM: bring identification

If you want a physical local SIM, bring your passport. Visitor registration rules vary by operator and nationality, and store staff may need to complete the activation. One explicitly says non-Hungarian customers cannot activate its Instant pay-as-you-go SIM online; Yettel's visitor guidance likewise directs foreign physical-SIM buyers to its stores with valid passport documents.

Do you need a Hungarian phone number?

For a short city break, often not. Maps, messaging and app-based bookings can work with a data-only eSIM. A local number becomes more useful if you need ordinary local calls, are staying longer, or want businesses to call you back.

Public Wi-Fi and security

Cafés, hotels and other visitor venues commonly provide Wi-Fi, but do not make open public Wi-Fi your only connectivity plan. Use mobile data for banking or sensitive logins when possible, keep your phone locked, and enable device tracking before the trip.

Tipping without the awkwardness

Check the bill before adding a tip: some restaurants include a service charge, so automatically adding another percentage can mean tipping twice. Where service is not included and you want to tip, a modest restaurant tip is normal. Do not rely on one universal percentage for every venue; the bill and service style matter.

A simple setup for most visitors

  • EU/EEA plan with included roaming: keep your home SIM unless the fair-use allowance is too small.
  • Short non-EU trip: compare a tourist eSIM before departure with a local operator's current visitor offer.
  • Need calls or a longer stay: visit an operator shop with your passport and ask for the current prepaid options.
  • Cash: withdraw a modest amount of HUF and avoid accepting unsolicited ATM help.

Best money rule: price things in forint, read the conversion screen, and keep enough cash for convenience — not enough to become a problem if your wallet disappears.

Frequently asked questions

Should I pay in euros or Hungarian forint?

Hungary uses the Hungarian forint (HUF). If a card terminal or ATM offers to convert the transaction into your home currency, compare carefully and usually choose the HUF/local-currency option so your own card provider handles the conversion instead of accepting an on-the-spot conversion rate.

Do I need cash in Budapest?

Cards are useful for most visitor spending, but a modest amount of forint is still handy for small purchases and places where card payment is unavailable or inconvenient. There is little reason to carry a large wad of cash.

Can a visitor buy a Hungarian SIM or eSIM?

Yes. Current visitor products are offered by major Hungarian networks. Requirements differ: Yettel advertises tourist eSIMs that can be bought before arrival, Telekom sells a Travel SIM/eSIM through its stores, and One says non-Hungarian customers should activate pay-as-you-go SIMs in a One store with accepted identification.
