The 3 hidden costs of money abroad
- Exchange-rate spread: Banks and many cards add a markup over the real rate — often 1–3% on every foreign-currency payment.
- Roaming & overpriced data passes: Mobile data outside your home region adds up to several euros/dollars a day — or leaves you offline.
- ATM & foreign-transaction fees: Foreign ATMs and "Dynamic Currency Conversion" at checkout are expensive traps.
The setup below neutralises all three with tools I actually use.
My travel money setup at a glance
| Piece | Solves | My tool |
|---|---|---|
| Convert & spend | Exchange-rate spread | Wise multi-currency account (real mid-market rate) |
| Internet | Roaming charges | Airalo eSIM (per-country data plan) |
| Backup card | Acceptance gaps | A Visa/Mastercard (+ optional travel rewards card) |
Wise — pay and convert at the real exchange rate
A Wise multi-currency account lets you hold and convert USD, EUR, GBP and 40+ currencies at the real mid-market rate — without the hidden markup banks bake into their rates. The linked debit card spends abroad at the same rate. For anyone who travels or receives money in several currencies, this is the single biggest saving: you stop paying the 1–3% spread on every transaction.

Airalo — a travel eSIM instead of roaming
Instead of expensive roaming or hunting for a local SIM, you load an Airalo eSIM for your destination onto your phone in minutes — ready the moment you land. For most trips a cheap per-country data plan is plenty; regional plans cover multiple countries. No SIM swap, no roaming surprise on your bill.

The biggest saving comes first
Before the eSIM or the backup card: a Wise account at the real mid-market rate saves the most on every single foreign-currency payment.

How to avoid exchange-rate fees abroad
Two simple rules save the most money:
- Always pay in the local currency. When a terminal offers to charge you in your home currency ("Dynamic Currency Conversion"), decline — that conversion is set by the merchant and is almost always worse.
- Use an account that converts at the mid-market rate. A Wise account (or similar) removes the 1–3% spread banks add, which on a longer trip easily adds up to real money.
