Why Every Traveller Needs a Wise Card Before Visiting Thailand, The Complete Money Guide for 2026

 Why Every Traveller Needs a Wise Card Before Visiting Thailand

The Complete Money Guide for 2026

If there is one piece of travel advice I give to absolutely everyone who tells me they are visiting Thailand it is this, sort your money before you get on that plane. I have been travelling to and living in Thailand for years now and the number of people I have met who have overpaid on bank fees, got stung at ATMs, had their card blocked abroad or paid way over the odds on currency exchange is genuinely heartbreaking when the solutions are so simple, completely free to set up and take less than ten minutes to sort before you travel. This is your complete money guide for visiting Thailand in 2026 and by the end of it you will have everything sorted.

💳 Step One: Get a Wise Card

Wise is a financial technology company that offers a multi currency account and debit card designed specifically for people who travel or send money internationally. Previously known as TransferWise it has grown to become one of the most trusted travel money solutions in the world with over 16 million customers globally. The Wise card works exactly like a regular debit card and is accepted everywhere that Mastercard is accepted worldwide, which in Thailand means restaurants, shops, hotels, supermarkets and ATMs across the entire country.

Wise uses the real mid market exchange rate which is the fairest rate available and charges only a small transparent fee that is clearly shown before you confirm any transaction. No hidden charges, no surprise fees and no nasty shocks when you check your bank statement after your trip. Sign up free here  

💰 Why Wise Beats Your Regular Bank Card Every Single Time

Most UK high street banks charge a foreign transaction fee of between 2% and 3% on every single purchase you make abroad, plus an additional ATM withdrawal fee on top of that. 

Thai ATMs also charge a fixed local fee of around 220 baht every time you withdraw cash regardless of which card you use. Over a two week holiday those charges add up to a significant amount of money that could have been spent on incredible food, tours and experiences instead.

Wise solves all of this instantly. What you see is what you pay and that transparency alone makes it worth every second it takes to set up. Get your free Wise card here before your trip

🔄 Step Two: Download Revolut as Your Backup

Once your Wise card is sorted the next thing to do is download Revolut as your backup card and budgeting tool. Having two cards when you travel is not a luxury, it is essential. If your Wise card is ever lost, stolen or temporarily blocked while you are in Thailand you need a backup immediately and Revolut is the perfect solution. Sign up free here 

Revolut is also exceptional for budgeting as it offers real time spending notifications and the ability to set daily spending limits across different categories which is incredibly helpful if you are keeping track of your daily budget in Thailand. Both Wise and Revolut are completely free to sign up for and I genuinely recommend having both active and loaded before you board your flight.

🏧 Using Your Cards at Thai ATMs: The One Thing You Must Know

This is the single most important piece of financial advice I can give you about Thailand and I cannot stress it enough. When you use any foreign card at a Thai ATM the machine will ask you whether you want to be charged in Thai Baht or your home currency. Always, always, always select Thai Baht. Every single time without exception.

This is called Dynamic Currency Conversion and if you select your home currency the ATM applies its own extremely unfavourable exchange rate which will cost you significantly more money. 

Select Thai Baht and let Wise or Revolut handle the conversion at their much better rates. I have an entire TikTok video about this exact topic that has helped thousands of people avoid this mistake watch it here

📱 Step Three: Sort Your eSIM Before You Land

While you are sorting your finances there is one more thing to get set up before you travel and that is your eSIM. An eSIM is a digital SIM card that you download directly to your phone before you leave home which means you are connected to data the moment your plane lands in Thailand with no queuing at airport SIM card kiosks and no hunting for a phone shop on your first day.

I use and recommend Airalo  and Saily  both of which offer affordable Thailand data packages that you can activate instantly. Being connected from the moment you land means you can use Google Maps, contact your hotel, check your Wise app and stay safe from day one.

🔒 Step Four: Protect Your Banking Apps With a VPN

This one is something most travellers never think about until it is too late. When you are using public WiFi in hotels, cafes, restaurants and co working spaces in Thailand you are potentially exposing your banking apps and personal data to security risks. A VPN encrypts your internet connection and keeps your financial information completely private no matter which network you are connected to.

I use and recommend NordVPN and Surfshark both are affordable, easy to use and you can protect multiple devices on a single subscription. 

Set it up before you travel and switch it on every single time you connect to public WiFi. Your bank details and your peace of mind are worth it.

🛡️ Step Five: Sort Your Travel Insurance

The final piece of the puzzle before your trip is travel insurance and please do not skip this one. 

Medical costs in Thailand without insurance can be extremely expensive and no amount of money saved on bank fees is worth the risk of being caught without cover. I use and recommend SafetyWing  which offers flexible and affordable travel and medical insurance that you can buy even after you have already left home, and Visitors Coverage  for comprehensive trip protection. 

Both are trusted, straightforward and genuinely good value.
