The Biggest Mistakes People Make When Using Bunq Abroad

Bunq markets itself as a borderless, travel friendly bank, and for many Europeans it genuinely can be a smart way to spend abroad. Yet every summer, the same stories appear on forums and social media: unexpected foreign exchange costs, cards declined at hotel desks, ATM withdrawals that suddenly become expensive, or support responses that arrive much later than hoped. Most of these problems are avoidable if you understand how Bunq actually works outside your home country. This guide walks through the biggest mistakes people make when using Bunq abroad and shows, with concrete real world examples, how to avoid them.

Misunderstanding Bunq’s Foreign Exchange Costs

One of the most common mistakes is assuming Bunq is always “zero fee” abroad. In reality, Bunq uses the Mastercard exchange rate plus a small network fee on non euro transactions. At the time of writing, Bunq advertises its ZeroFX system, which generally applies a 0.5 percent network fee to foreign currency card payments on top of the raw Mastercard rate. That is lower than a typical traditional bank card that might charge 2 to 3 percent on every purchase, but it is not completely free. If you spend the equivalent of 1,000 euros in US dollars during a New York city trip, that network fee alone is roughly 5 euros just for the conversion.

Confusion grows because different Bunq plans treat foreign exchange slightly differently. Core, Pro and Elite accounts are designed for everyday and frequent international use, so card payments abroad are included at the Mastercard rate with that small network fee. By contrast, Free users may face a threshold system where the first slice of foreign spending benefits from ZeroFX, and larger purchases attract a higher conversion markup on the amount above a certain monthly limit. A traveler who upgrades to a paid plan for one month before a long trip to Japan can often recoup the subscription cost simply through lower conversion fees on hotels, rail passes and restaurant bills.

Where people get caught out is when they compare Bunq only to their domestic bank rather than to travel specialists. A German traveler used to paying 1.75 percent in foreign fees at a legacy bank might rightly feel that Bunq’s approximate 0.5 percent is a bargain. Someone comparing Bunq to a niche card that offers zero extra FX markup, however, will notice the small difference. The key is to recognize Bunq as a relatively low cost option, but not to assume the exchange rate is always absolutely the best on the market.

Before a big trip, it is worth running a simple test: check Mastercard’s published exchange rate for your destination currency and then make a small online purchase in that currency with your Bunq card. When the transaction settles, compare the final effective rate to the published one. That quick exercise shows you, in real numbers, what Bunq will cost you on a 200 euro dinner in San Francisco or a 500 euro hotel bill in Bangkok.

Falling for Dynamic Currency Conversion Traps

Dynamic currency conversion, or DCC, is one of the most expensive and misunderstood quirks of paying abroad. At card terminals and ATMs outside the eurozone, travelers are often asked whether they want to pay in their “home currency” or the “local currency.” Choosing home currency sounds comforting, especially when the terminal flashes reassuring messages about knowing the exact amount in euros. The problem is that the merchant or ATM operator sets the exchange rate in that case, usually with a heavy markup.

With Bunq, this mistake is especially painful because it undermines the whole point of using a bank that gives you close to the Mastercard rate. Imagine you are in a London pub, and the bill comes to 40 pounds. The terminal offers to charge you 48 euros directly, using its own conversion. The spot rate that day might translate 40 pounds to about 46 euros. If you choose “EUR” at the terminal, you are effectively paying a couple of euros extra on a single round of drinks, even before Bunq’s tiny network fee enters the picture. Over a week of meals, hotel incidentals and train tickets, that choice can add up to 20 to 40 euros of pure waste.

The same trap appears at foreign ATMs in tourist areas. In Bangkok or Denpasar, cash machines aimed at visitors routinely offer withdrawals in euros with a “guaranteed rate.” A traveler with Bunq might withdraw 10,000 Thai baht, shown as 280 euros using the ATM’s markup, when the market rate would have been closer to 260 to 265 euros. On top of that, the ATM may add a separate fixed fee of 200 to 250 baht. The result is that the savings Bunq users expect from ZeroFX are wiped out entirely by a single bad choice on the ATM screen.

The simple rule is this: with Bunq, always pay in the local currency of the country you are visiting. If your card is euro based, that means choosing pounds in the United Kingdom, dollars in the United States, kuna or its successor currency in Croatia, baht in Thailand and so on. Let Bunq and Mastercard handle the conversion. It may feel counterintuitive to reject the familiar euro amount on screen, but that is precisely how you keep your costs down.

Assuming All Bunq Plans Work the Same Way Abroad

Another frequent mistake is signing up for Bunq just before a trip, choosing a plan at random, and assuming all cards behave the same way at foreign terminals and ATMs. In practice, the differences between Free, Core, Pro and Elite tiers matter quite a bit once you land abroad. They affect not just exchange rates and networks, but also ATM fees and the number of physical or virtual cards you can carry.

Take ATM withdrawals as a concrete example. According to Bunq’s latest help center information, Pro and Elite users can typically make their first six ATM withdrawals per monthly billing cycle without an extra Bunq fee, while Core users pay a reduced fee on a limited number of withdrawals before higher charges kick in. Free users, by contrast, may pay a flat fee on every withdrawal, such as 2.99 euros each time, and are limited to ATMs that support Apple Pay or Google Pay if they do not have a physical card. Someone on a long stay in Mexico who pulls out small amounts of cash daily from convenience store ATMs could easily spend 25 to 40 euros per month just in Bunq withdrawal fees, plus any local ATM charges, simply because they chose the wrong plan for their travel style.

Card type also matters. Bunq issues Mastercard debit cards by default and used to market a Travel Card designed to behave like a credit card at many terminals. While the travel functionality lives on in current debit cards, not every merchant understands the difference. Some car rental desks and hotel front desks around the world still insist on a “real credit card” for security deposits, even when a Bunq card carries the Mastercard logo. Travelers who arrive in the United States or South Africa planning to rely solely on Bunq for car hire regularly report being turned away or asked for a different card for the deposit.

The smartest approach is to match your plan to your itinerary. A digital nomad spending three months shuttling between Portugal, Spain and Morocco may justify an Elite subscription for its additional features, multiple subaccounts and potentially bundled travel insurance. Someone planning a one week break in Croatia might upgrade from Free to Core or Pro for just that month, purely to reduce ATM fees and give themselves more card options, then downgrade when they return. Taking ten minutes to understand the current terms of each plan, and making a deliberate choice based on your real travel needs, can save a surprising amount of money and frustration.

Ignoring ATM Limits, Fees and Local Operator Charges

Travelers often assume that if they see the Mastercard logo on an ATM, their experience with Bunq will be seamless and cheap. In reality, several layers of limits and fees can interact in confusing ways. Bunq itself enforces daily limits on cash withdrawals for security reasons, often around 250 euros per calendar day for newly verified accounts and up to 1,000 euros per day for longer established users. If you sign up for Bunq shortly before a trip to Argentina and then try to withdraw the equivalent of 800 euros in one go to pay for a Patagonia trekking tour, there is a real risk the transaction will be declined even though your account balance is healthy.

On top of Bunq’s own limits, foreign ATMs frequently impose their own maximums and surcharges. In parts of the United States, for instance, independent ATMs in corner stores or gas stations may only allow withdrawals of 200 to 300 dollars at a time and charge a flat 3 to 5 dollar fee per withdrawal. In Thailand, some bank ATMs aimed at tourists have been known to assess a fixed charge of 200 to 250 baht per transaction on foreign cards. Bunq does not control, and generally does not refund, these operator fees. A traveler trying to avoid their home bank’s foreign fees by using Bunq can still bleed cash through small, frequent withdrawals at these machines.

The combination of limits and local charges can create a trap. Picture a couple spending ten days in New York. Their apartment rental requires a cash deposit paid on arrival, so they attempt to take out 800 dollars at once. The ATM caps single transactions at 400 dollars, Bunq’s daily limit stops them from doing another 400, and each withdrawal carries a 4 dollar local fee. By the time they have pieced together enough cash over several days, they have paid 16 to 20 dollars in local ATM charges alone, plus any Bunq withdrawal fees once they exceed their monthly free quota.

The fix is preparation. Before departure, check your current ATM limits in the Bunq app and raise them if necessary and possible. Once abroad, withdraw larger amounts less frequently from ATMs attached to mainstream banks, which tend to be more transparent about fees. If you know you will need 600 dollars for a tour deposit in Peru or 50,000 yen in cash for a rural guesthouse in Japan, plan a day or two ahead so you can work within Bunq’s limits without scrambling at the last minute.

Relying on Bunq Alone for Deposits and Offline Situations

Another major misunderstanding is treating Bunq as a complete replacement for a traditional credit card when traveling, especially for security deposits and offline transactions. While Bunq’s cards carry the Mastercard logo and work in most chip and PIN or contactless scenarios, some industries are slower to adapt. Hotel chains, car rental companies and certain toll systems may still require a conventional credit card with a credit line, not a debit card drawing directly on your balance.

Consider a traveler flying into Lisbon planning to pick up a rental car from a global brand at the airport. The rental terms specify a 700 euro deposit that will be preauthorized on a credit card on collection. At the counter, the agent swipes the Bunq card, but the system recognizes it as a debit product and refuses to hold the deposit without actually debiting the account. Some companies will adapt by taking the deposit as a real charge and refunding it at the end of the rental, but many simply decline the card and ask for a traditional credit card in the driver’s name. Faced with no alternative, the traveler might have to accept a more expensive walk up rental from another company that does accept debit cards, or forgo the car entirely.

Similar issues arise in hotels that rely on preauthorizations to cover minibar charges and potential damages. In cities like New York, London or Dubai, it is common for hotels to place a hold of 100 to 200 units of local currency per night on a guest’s card. With Bunq, those funds are ring fenced from your available balance for days or even weeks until the hotel releases them. That can be a nasty surprise for backpackers who keep most of their travel budget in a single Bunq account and suddenly discover 600 dollars locked up as a security hold.

Travelers also underestimate how often card terminals operate offline. On long distance trains in rural France, at highway toll booths in Italy, or on ferries in Greece, systems may approve small transactions without a real time connection to the bank. Some of these setups are configured only for credit cards, not for modern debit products, so a Bunq card that worked flawlessly in city supermarkets could fail on a motorway toll barrier late at night. That is a stressful moment you want to avoid.

The practical solution is redundancy. Even if you love Bunq’s interface and budgeting tools, bring at least one additional card from a different provider when you travel, ideally a proper credit card with no or low foreign transaction fees. Use Bunq for day to day spending, but keep the other card for car rentals, hotel deposits and any terminal that refuses your debit card. That way, Bunq’s strengths are maximized, and its limitations do not derail your trip.

Overlooking Security Features, Fraud Risks and Support Delays

Bunq’s security model is strict, which is positive from a fraud prevention perspective but can surprise travelers who run into problems far from home. The bank uses real time monitoring and may temporarily block payments that appear unusual, such as a sudden series of high value transactions in a new country. In some cases, Bunq introduces waiting periods on actions that might signal account takeover, such as adding a new device or making a large transfer to a new recipient. This is helpful if someone steals your phone in Barcelona and tries to empty your account, but it can feel alarming if you are standing at the check in desk of a hotel in Lima and your card is suddenly declined.

Fraud itself, while relatively rare, is more stressful abroad. Travelers have described scenarios where their card details were compromised at a restaurant or online merchant, leading to a cascade of unauthorized payments in a different country. In one widely shared account, a user noticed several hundred euros charged in France shortly after using their Bunq card in the Netherlands. Although Bunq ultimately refunded the losses, the process involved in app chats, waiting for investigations and temporarily living without a key card while traveling can be extremely inconvenient.

Unlike many traditional banks, Bunq does not operate a public phone hotline for everyday users. Most support flows through the in app chat, which can be slow at peak times, particularly during European summer holidays when many people are traveling at once. A backpacker who loses their phone in Colombia, for instance, may struggle to authenticate into the app on a new device immediately, delaying their ability to freeze cards or contact support. That lag can be frightening when your only access to money is through Bunq.

This is why it is vital to set up security features before departure. Activate location based security only if you are sure your travel route is accurately reflected, and adjust card limits so that legitimate transactions in your destination country are less likely to be flagged as suspicious. Make sure you have a second factor of authentication that is not tied solely to one phone, such as a backup device or a way to receive codes while abroad. Most importantly, avoid relying on Bunq as your sole store of travel funds. Keep some cash in a money belt or hotel safe and maintain access to a backup bank account, so that if Bunq freezes your card as a precaution, your trip does not grind to a halt.

The Takeaway

Used thoughtfully, Bunq can be a powerful tool for travelers, combining competitive exchange rates with flexible budgeting features and a modern app. Most of the horror stories about Bunq abroad come from the same set of avoidable errors: misunderstanding how foreign exchange and plan tiers actually work, accepting dynamic currency conversion at ATMs or terminals, ignoring limits and local operator fees, expecting a debit product to behave exactly like a traditional credit card, and overlooking the way Bunq handles security and support.

To get the best from Bunq on the road, treat it as one strong component in a broader travel money strategy, not as your only lifeline. Pay in the local currency instead of euros, choose the plan that matches your itinerary, plan ATM withdrawals carefully, and always carry a backup card and some cash. With those simple habits in place, you can enjoy the benefits of a modern mobile bank while sidestepping the biggest pitfalls that catch so many travelers off guard.

FAQ

Q1. Is Bunq really cheaper than a traditional bank card for spending abroad?
In many cases yes, because Bunq typically uses the Mastercard exchange rate plus a relatively small network fee, while traditional banks often add 2 to 3 percent. The exact saving depends on your home bank’s charges and the Bunq plan you choose.

Q2. Should I always choose to pay in euros when using Bunq outside the eurozone?
No. With Bunq, you almost always want to pay in the local currency of the country you are in. Choosing euros activates dynamic currency conversion, where the merchant sets a poor rate that usually costs more than letting Bunq convert at the Mastercard rate.

Q3. How many ATM withdrawals can I make for free with Bunq while traveling?
It depends on your plan and may change over time, but higher tier plans typically include a limited number of low cost or free withdrawals per monthly billing cycle. After that, Bunq charges a fee per withdrawal, and foreign ATM operators can add their own charges on top.

Q4. Can I rely on my Bunq card for hotel and car rental deposits?
You can try, but you should not rely on Bunq alone. Many hotels and car rental companies still require a traditional credit card for security deposits and may not accept a debit based Bunq card, even though it carries the Mastercard logo.

Q5. Does Bunq refund the fees foreign ATMs charge me?
Generally no. If an ATM in another country adds a local surcharge per withdrawal, that fee is set and kept by the ATM operator, not by Bunq. You pay that in addition to any Bunq withdrawal fees that apply to your plan.

Q6. What happens if my Bunq card is lost or stolen while I am abroad?
You should immediately freeze the card in the Bunq app, order a replacement and contact support through in app chat. Bunq may investigate any unauthorized transactions before issuing refunds, so having a backup card and some cash is important while you wait.

Q7. Is it worth upgrading my Bunq plan just for a single trip?
For longer or expensive trips, often yes. Upgrading for one month to a plan with better ATM terms and lower foreign transaction costs can save more than the subscription fee, especially if you expect large hotel bills or frequent cash withdrawals.

Q8. Can I use Bunq as my only bank when traveling long term?
Some digital nomads do, but it is safer to treat Bunq as your main day to day spending account and keep at least one additional account or card elsewhere. That way, if there is a technical issue, security check or card loss, you still have access to money.

Q9. How can I see what exchange rate Bunq gave me on a foreign purchase?
After a transaction settles, you can check the original amount and the final euro charge in the app. Comparing that to the Mastercard reference rate for the day gives you a clear picture of the effective rate and any small network fee.

Q10. Is Bunq a good choice for trips within the eurozone as well as outside it?
Within the eurozone, card payments are usually free of foreign exchange issues, so Bunq works smoothly and cheaply for everyday spending. The biggest savings and pitfalls arise when you cross into non euro countries, where understanding fees, limits and currency choices becomes more important.
