Euros in the pocket, data on the phone, a card that actually works at a péage machine. That is the unglamorous layer. Get it wrong and every other page on this cluster becomes a mime show. Get it right in arrivals and you can ignore it until the next café.
Currency, then the phone
Euro (€). Notes and coins. Contactless (sans contact) is normal in cities, supermarkets, and Métro gates that take cards. Market stalls and some village cafés still want cash. Keep small notes. Cover the keypad at an ATM. French ATMs generally take UK debit cards; your bank will add a fee, and some French machines add another. Withdraw less often.
Cards. Visa and Mastercard. American Express is patchy. Tell the UK bank you are travelling. Contactless limits exist; a PIN still happens. Péage lanes marked with card symbols are not a puzzle if the card has a chip.
There is no tourist "PromptPay". France pays with card, cash, and sometimes a phone wallet. A UK banking app is not a French carte bancaire. Do not stand at a motorway toll waving a screenshot.
Airport Wi-Fi is for the first message home. Buy the SIM or eSIM before you leave the hall if you can face the kiosk. Orange, SFR, Bouygues, and Free are the names on the board. Tourist eSIMs sold before you fly are often the calmer option. We will not invent a fake €19.99 SKU that was true for one kiosk in 2024. Read the board. Passport if they ask. Keep the UK number for bank texts.
A compact Type E travel adapter belongs in the personal item.
Navigo, not folklore
In Île-de-France the useful products are Navigo Easy (pay-as-you-go on a card) and Navigo Découverte (weekly, Monday–Sunday, photo required). A weekly pass only pays if your week aligns. Singles add up faster than pride will admit. The app layer moves; the principle does not: zones, and CDG is not zone 1.
Regional TER and TGV INOUI / OUIGO are separate tickets. OUIGO is cheaper and stricter. SNCF Connect is the official starting point, not a random reseller with a countdown clock.
What this page will not pretend
We will not quote a fake roaming "free in the EU" as if a UK SIM still behaved like 2019. Check your UK operator. We will not tell you every stall takes Apple Pay. We will not tell you to carry no cash.

Money and SIM cards is a working page on La Porte, not a souvenir. Use it with the week you travel. Money and SIM cards sits in a country that is easy to over-plan and easy to under-prepare. The money and sim layer is where visitors collect names. This page is the opposite: what to do first, what to skip, and which sibling guide holds the rest.
France rewards a slow unit. One arrondissement, one valley, one appellation, one park trail. The photograph of five landmarks in five days is a real holiday, and it is also a queue with a passport. If you only have three nights, spend two of them in the same bed. The third night is for a train, not a third hotel.
Working a visit
Practical France is sockets (Type E/F, 230 V), tap water that is safe, pharmacies that are the real clinic for minor trouble, and a lunch hour that still closes a village. Cards work in cities. Cash still opens some park kiosks, some island boats, and some market stalls that have never seen contactless. A lightweight adapter belongs in the personal item, not the hold.
We will not write as if every reader is on a gap year, or as if every reader is in a palace hotel. We will not flatten 'the south' into one climate. We will not treat a strike day, a jour férié, or a Tuesday museum closure as a personality quirk of the French. They are calendars. Check them. Then use Money and SIM cards as a pin, not as scripture.
Cross the five guides instead of cloning them. La Porte holds trains and the first week. La Terre holds weather and park gates. L'Esprit holds museum Tuesdays and the Revolution. La Table holds the market morning and the wine list. Le Moteur holds the Tour, the working week, and why August is empty in Paris and full on the coast.
