Before anything else: three habits that cost nothing

These save more money and hassle than any product below, and they are free.

• Always pay in local currency. When a card terminal or ATM offers to charge you in your home currency, decline. That option hands the exchange rate to the merchant’s processor, and it is reliably worse than your bank’s. This one habit can cost you 3 to 12 percent per transaction if you get it wrong.
• Carry a second card, on a different network, kept separately. Cards get blocked, swallowed, and lost, and Visa and Mastercard acceptance genuinely differs by country.
• Tell your bank you are travelling. A blocked card on day one outweighs every fee you might optimise away.

eSIM: Airalo

Why it wins: Airalo covers 200+ countries and regions, more than anyone else, which is exactly what you want from the one eSIM you buy without researching each destination. The app is clean, setup takes a couple of minutes, support runs around the clock, and you can top up in-app instead of buying a whole new plan mid-trip. For the widest range of trips and travellers, it is the “it will just work” default, and that reliability is worth more than shaving a pound off the price.

The one caveat we would not hide: because every eSIM resells a local network, the best provider changes in a few specific places. Bali is the classic example, where the strongest island-wide network is Telkomsel and Airalo resells Indosat and Hutchison instead. That is why our country guides get specific about the carrier. But as a default you pack once and trust anywhere, Airalo is the pick.

VPN: NordVPN

Why it wins: the single most useful thing a travel VPN can have is a fast server close to wherever you are, and close to home for your own services. NordVPN’s network is one of the largest anywhere, with thousands of servers across roughly 125 countries, so you almost always have a quick local option. It also has the strongest track record of the three for actually getting streaming working from abroad, and it holds up in heavily filtered countries like China when you switch on obfuscation. For the traveller who wants one VPN that quietly does everything, it is the pick.

What the marketing oversells: the “hackers on hotel wifi will steal your bank details” pitch is largely a threat model from a decade ago, since almost all traffic is encrypted now. The honest reasons to run a VPN abroad are getting your home streaming and banking apps working, and keeping the network operator out of your browsing. NordVPN does both well.

Travel card: Wise

Why it wins: Wise gives you the real mid-market exchange rate with a small, clearly stated fee (from around 0.43 percent) and, crucially, no weekend surcharge. That predictability is what makes it the safe default: you are never ambushed by a markup on a Saturday. It works the same for any nationality, holds and converts more than 40 currencies, and the pricing is the most transparent in the category. For spending abroad and moving money without nasty surprises, it is the low-friction pick.

The honest trade-off: for pure card spending on weekdays, under plan limits, Revolut’s 0 percent markup can technically edge Wise. But Wise wins on never having to think about which day it is or which plan tier you are on, and for most travellers that simplicity is worth more than the last fraction of a percent.

Insurance: Heymondo

Why it wins: most travellers take defined trips with a return date, and Heymondo is built for exactly that, with per-trip cover, strong emergency medical limits, and 24/7 assistance. Its standout feature is an in-app doctor chat, so a worrying symptom at 2am in an unfamiliar place gets a real answer without a hospital dash. For the typical holiday or work trip, it is the pick.

The caveat we have to be straight about: insurance is the one category nobody can road-test without actually making a claim, so this pick comes from reading the policy wording rather than from surviving a claims process. We tell you which document and which clauses, and we do not pretend to experience we do not have. That standard is in how we test.

Before you buy any policy, two things decide most rejected claims: declare pre-existing conditions, and check the activities exclusions before you rent a scooter. Full detail in our travel insurance guide.

The whole stack, sorted in ten minutes

If you pack the four winners above, tell your bank you are travelling, carry a backup card, and always pay in local currency, you have covered the parts of a trip that quietly go wrong. Each pick has a full guide behind it if you want to go deeper before you buy, and every recommendation is chosen the same way, described in how we test.

We earn a commission if you buy through the links here, at no extra cost to you, and it never sets the order. The details are in our affiliate disclosure.

The stack, tuned per destination

The generic stack above survives contact with most countries; the tuned versions matter where one decision dominates. Japan is a carrier-coverage and cash-culture story, and Thailand turns on an ATM fee and an insurance clause most policies hide. More destinations join as we cover them.
