Money While Travelling

Money planning should never depend on only one method. The safest approach is to carry a combination of payment cards, small cash, and digital payment options. Even in countries where card payments are common, cash may still be needed for taxis, markets, tips, public toilets, local transport, rural areas, and emergencies.

A good travel money setup usually includes one main debit or credit card, one backup card stored separately, a small amount of local cash, and a mobile wallet such as Apple Pay or Google Pay. If possible, you should also have emergency access to money through your bank app or a trusted family contact.

Before departure, check whether your bank charges foreign transaction fees, ATM withdrawal fees, currency conversion fees, or international card usage fees. Also check your daily withdrawal limit, card spending limit, and whether your bank requires a travel notice.

Always Pay in the Local Currency

One of the most important money rules abroad is simple: when a card terminal or ATM asks whether you want to pay in your home currency or the local currency, choose the local currency.

Paying in your home currency may look convenient, but it often uses a system called Dynamic Currency Conversion. This means the shop, restaurant, hotel, or ATM operator applies its own exchange rate, which may be worse than the rate used by your bank or card network.

Choosing the local currency usually gives you a better conversion rate and avoids unnecessary hidden markups.

Cash vs Card by Destination

The best payment method depends on where you are travelling. In many European cities, card payments are widely accepted, but cash is still useful for small purchases, local cafés, public toilets, tips, and markets.

In Japan, cards are accepted in many modern places, but cash is still useful for smaller restaurants, temples, vending machines, older shops, and rural areas. In Thailand, Sri Lanka, Vietnam, Indonesia, and many parts of Southeast Asia, cash is very important for street food, tuk-tuks, local buses, beaches, small shops, and traditional markets.

In the United States, Canada, the United Kingdom, Australia, and much of Northern Europe, card and digital wallet payments are widely accepted. However, even in these destinations, carrying a small amount of cash is still a good emergency habit.

A practical rule is to arrive with enough local cash for the first 24 hours. This should cover airport transport, food, SIM card purchase, small tips, and emergencies.

ATM Tips Abroad

ATMs are often the easiest way to get local cash, but they must be used carefully. Whenever possible, use ATMs attached to real banks, especially during opening hours. Avoid isolated ATMs, nightclub ATMs, street machines in poor condition, and machines that look damaged or modified.

When withdrawing cash abroad, choose the local currency, decline expensive currency conversion offers, cover your PIN, and read every screen before confirming the transaction.

It is often better to withdraw a reasonable amount once or twice instead of making many small withdrawals, because some banks and ATM operators charge fixed fees for every withdrawal.

How Much Cash Should You Carry?

The right amount of cash depends on your destination, travel style, and length of stay. For short city trips in card-friendly countries, a small emergency amount may be enough. For countries where cash is still common, you may need more.

Do not keep all your cash in one place. Keep some in your wallet, some in a separate pouch, and some in your hotel safe or luggage. If your wallet is lost or stolen, you should still have backup money available.

Cards, Travel Cards and Digital Wallets

Travellers should ideally carry at least two cards. One card can be used for daily spending, while the second card should be kept as a backup. If one card is blocked, lost, damaged, or rejected, the second card can save the trip.

Credit cards are often useful for hotels, car rentals, security deposits, and larger purchases. Debit cards are useful for ATM withdrawals and everyday spending. Prepaid travel cards can also be helpful, but you should check loading fees, withdrawal fees, exchange rates, and refund rules before using them.

Mobile wallets such as Apple Pay and Google Pay are convenient and secure, but you should not depend only on your phone. If your phone battery dies, your phone is stolen, or mobile payments are not accepted, you still need a physical backup card.

Banking Security While Travelling

Before travelling, open your banking app and check that everything works. Make sure you know how to freeze your card, change limits, view transactions, and contact your bank from abroad.

Enable instant transaction notifications. These alerts help you detect suspicious card activity quickly. Save your bank’s emergency phone number somewhere outside your phone, such as in a printed document or secure travel folder.

If your bank still requires travel notices, inform them before departure. This can reduce the risk of your card being blocked after international transactions.

SIM Cards, eSIMs and Roaming

Internet access is one of the most important travel tools. You need it for maps, translation, ride-hailing apps, hotel bookings, airline updates, banking apps, emergency contact, and travel planning.

There are four main ways to stay connected while travelling:

• International roaming from your home operator
• Local physical SIM card
• Travel eSIM
• Portable Wi-Fi device

International roaming is convenient because your normal number continues to work. However, it can be expensive outside your home roaming zone. Before using roaming, check the daily price, data limit, fair-use rules, included countries, and extra charges.

Local SIM Cards

A local SIM card is often one of the cheapest options for longer stays. It is especially useful in countries where local data plans are affordable, such as Thailand, Sri Lanka, Vietnam, Indonesia, Turkey, Morocco, Egypt, Mexico, and many South American destinations.

A local SIM can give you better local network access, cheap mobile data, and sometimes a local phone number. This can be useful for food delivery apps, taxi apps, local bookings, and customer service calls.

However, your phone must be unlocked, and in many countries you may need to show your passport to buy a SIM card. In some destinations, SIM registration is mandatory.

eSIMs for Travel

An eSIM is a digital SIM that can be installed on compatible phones without inserting a physical SIM card. It is one of the easiest options for modern travellers because you can buy and install it before departure, then activate it when you arrive.

eSIMs are especially useful for short trips, multi-country travel, business travel, and travellers who want internet immediately after landing. They also allow you to keep your original SIM active for calls, SMS, WhatsApp, and banking verification messages.

Before buying an eSIM, check the following:

• Your phone supports eSIM
• Your phone is unlocked
• The destination country is included
• The plan includes enough data
• The validity period matches your trip
• The plan is data-only or includes calls and SMS
• Hotspot or tethering is allowed
• The provider uses reliable local networks

Physical SIM vs eSIM

A physical SIM is usually better if you need a local phone number, you are staying for several weeks or months, you need cheap local calls, or your phone does not support eSIM.

An eSIM is usually better if you want internet immediately after landing, you are visiting multiple countries, you do not want to remove your normal SIM, or you want to prepare everything before departure.

For many travellers, the best setup is to keep the original SIM active for banking verification messages and use an eSIM or local SIM for mobile data.

How Much Mobile Data Do You Need?

Data needs depend on how you travel. If you only use maps, messaging, translation, and basic browsing, 3GB to 5GB may be enough for a short trip. If you use social media, video calls, cloud backups, YouTube, TikTok, or remote work tools, you may need 10GB, 20GB, or unlimited-style data.

To save data, download offline maps, avoid automatic cloud backups, turn off automatic app updates, download entertainment before travelling, and use hotel Wi-Fi for large files when safe.

Wi-Fi While Travelling

Free Wi-Fi is available in many airports, hotels, cafés, restaurants, buses, trains, shopping malls, and tourist areas. It is useful, but it should not be treated as fully secure.

Public Wi-Fi can expose travellers to fake networks, data interception, malicious login pages, and attackers pretending to be official hotel or airport networks.

The safest rule is: use mobile data for banking, passwords, payments, and sensitive accounts whenever possible.

Public Wi-Fi Safety Tips

• Do not use public Wi-Fi for banking unless absolutely necessary.
• Use mobile data for sensitive transactions.
• Check the official Wi-Fi name with the hotel, airport, or café.
• Turn off automatic Wi-Fi joining.
• Forget public networks after using them.
• Avoid entering passwords on unknown networks.
• Use HTTPS websites.
• Use a trusted VPN where legal.
• Do not download unknown files or apps.
• Avoid public USB charging ports.

Hotel Wi-Fi should also be treated carefully. Even if it requires a password, it is still a shared network used by many guests.

Portable Wi-Fi Devices

A portable Wi-Fi router can be useful for families, groups, business travellers, content creators, or people who carry several devices. One portable router can connect phones, tablets, and laptops at the same time.

The advantages are convenience, shared connection, and easy use with multiple devices. The disadvantages are cost, battery life, possible daily data limits, and the risk of losing or damaging another device.

For solo travellers, an eSIM is usually easier. For families or work trips, portable Wi-Fi may be useful if the data allowance is generous.

Travel Apps to Install Before Departure

Install and log into important apps before travelling. Some apps require SMS verification, and this can become difficult once you are already abroad.

• Airline app
• Hotel booking app
• Google Maps or Apple Maps
• Offline maps
• Google Translate or another translation app
• Currency converter
• Banking apps
• Travel insurance app
• Ride-hailing apps such as Uber, Bolt, Grab, Careem, or local alternatives
• WhatsApp
• Cloud storage app
• eSIM provider app
• Public transport apps for the destination

Download offline maps before departure. This is useful if your SIM or eSIM does not work immediately after arrival.

Important Documents and Licences

Every traveller should carry both digital and physical copies of important documents. Documents should be easy to access but also protected from theft or misuse.

• Passport
• Visa or eVisa confirmation
• Return or onward flight ticket
• Hotel booking confirmation
• Travel insurance policy
• Vaccination or health documents if required
• Driving licence
• International Driving Permit if needed
• Emergency contact details
• Copies of bank cards with sensitive numbers hidden

If you plan to rent a vehicle, check whether your destination requires an International Driving Permit, an official translation, or a local recognition permit. Some rental companies ask for extra documents even when local law is more flexible.

Digital Backup System

Create a secure travel folder in cloud storage before departure. Keep important files available offline on your phone and share a copy with a trusted family member.

Your digital backup folder can include:

• Passport scan
• Visa or eVisa
• Insurance policy
• Flight tickets
• Hotel bookings
• Driving licence
• International Driving Permit
• Emergency contacts
• Bank emergency numbers
• Copies of prescriptions
• Important medical information

Do not store passwords or full card details in an unprotected note.

Health, Insurance and Emergency Money

Travel insurance should cover medical emergencies, lost luggage, theft, trip cancellation, delays, and activities you plan to do. Read the exclusions carefully.

Many policies do not automatically cover motorbike riding, scuba diving, skiing, hiking at high altitude, adventure sports, or pre-existing medical conditions. If you plan special activities, confirm coverage before departure.

Emergency money planning should include a backup card, emergency cash, travel insurance contact, a family contact, access to online banking, and digital copies of documents.

Common Mistakes to Avoid

• Relying on only one card.
• Exchanging all money at the airport.
• Choosing home currency instead of local currency at card terminals.
• Assuming roaming is free worldwide.
• Buying an eSIM without checking phone compatibility.
• Depending only on public Wi-Fi.
• Forgetting to download offline maps.
• Keeping all documents in one bag.
• Renting a vehicle without checking licence and insurance rules.
• Using public Wi-Fi for banking and passwords.
• Not carrying emergency cash.
• Forgetting that some apps require SMS verification.
