Monzo cards may not work in Thailand due to frozen card settings, disabled magstripe/ATM access in the app, or out-of-date merchant systems. Ensure your card is active for international use, enable the magstripe for older ATMs, check daily limits, and try selecting "Credit" instead of "Savings" on terminals.
Your card should work anywhere that Mastercard's accepted. Unfortunately, some merchants don't keep their systems up to date, so we occasionally see situations where our cards aren't recognised.
Card settings Your payment may decline if your card is frozen, or if online/contactless payments are turned off. You can update these in Manage card. Apple or Google Pay issues Wallet payments need your device unlocked and your card added correctly. Try re-adding your card if declines continue.
Debit cards have become increasingly popular and widely accepted in Thailand, especially in urban areas and tourist destinations. Many establishments, including restaurants, hotels, and retail stores, have card payment terminals that accept debit cards from major international networks like Visa and Mastercard.
Monzo App Not Working: How to Fix Monzo App Not Working
Why is my Monzo card suddenly not working?
It's likely a faulty card and needs replacing, but before you do that, check that you haven't accidentally frozen your card first. Also, when you try using your card, do you get any notifications from the Monzo app? If you get a notification, this might tell you what's wrong (and is likely NOT a faulty card issue).
Whenever you pay for something with your card, there's a code for the transaction. So when we see a payment with a gambling code, we can block it. Sometimes if the company doesn't have a gambling code, it can be tricky for us to stop the payment in time.
Some banks ask you to let them know if you're going to spend abroad so they don't block your card for suspicious activity. You can usually do this online or via your banking app. Monzo's the bank made for travel, so you don't need to worry about telling us if you're overseas.
I am abroad and I believe my card has been stopped, what do I do? When our systems recognise activity on your account that is similar to known fraud trends your card usage may be stopped as a precaution.
Your Revolut card handles 150+ currencies, including Thai Baht (THB). That means you can use it like a local debit card in Thailand. Order a physical card or use your free virtual card to start spending right away.
Is Monzo or Revolut better for spending abroad? Monzo doesn't charge foreign transaction fees for spending abroad on your debit card.

If you're unsure why your debit card is declining, call your financial institution to investigate what is causing the issue. It could be an expired or damaged card, a negative balance or any of the scenarios listed above. Often, a customer support representative can help you resolve the issue quickly.
The 2/3/4 rule for credit cards is a guideline, notably used by Bank of America, that limits how many new cards you can get approved for: no more than two in 30 days, three in 12 months, and four in 24 months, helping manage hard inquiries and credit risk. It's a strategy to space out applications, preventing too many hard pulls on your credit report and helping maintain financial health by avoiding over-extending yourself.
A card decline is when a card payment isn't authorized or accepted. There are many reasons a credit or debit card might be declined – for example, the card has expired, there are insufficient funds, or one of the parties in the payment ecosystem detects fraudulent activity.
This is because of new security rules, affecting all banks. Some places might not be ready for this change yet, so will show a regular decline message. We'll send you a notification when you need to retry with chip and PIN, and let you know in advance if your next payment needs to use chip and PIN.
No, the main FCA investigation into Monzo's anti-money laundering (AML) controls concluded in July 2025 with a £21 million fine, drawing a line under past failings and prompting significant system improvements, though the FCA continues to monitor the industry, with Monzo now focusing on enhanced compliance as it grows. The fine addressed issues from 2018-2022, and Monzo has since invested heavily in its financial crime framework and technology.
If you're great at budgeting and love to sample street food, £100 per week may be enough – but if you want to really indulge and try as many extra experiences as possible, allow twice this amount so that you don't need to keep counting your cash at the end of each day.
