Paris Airport SIM Cards: CDG, Orly and Whether You Need One at All

Charles de Gaulle is enormous and the phone provision is thinner than you would expect for an airport of its size. Before you plan around buying a SIM on arrival, it is worth knowing what is actually there.

Which networks operate in France

Four national networks: Orange, SFR, Bouygues Telecom and Free Mobile. Orange is the former state operator and has the widest rural coverage by a clear margin. Free is the cheap disruptor and is weaker outside towns.

For a visitor, Orange is the network you want under you, particularly if you are leaving the cities.

Where the desks are at CDG and Orly

Charles de Gaulle, CDG, has some operator presence and vending machines, but it is spread across three very large terminals and is not the reliable fixture travellers expect. Orly, ORY, is smaller and simpler but no better provisioned.

The practical problem is the same as everywhere: anything you find is past passport control and baggage reclaim, so the RER ticket machine, the taxi queue and the message to whoever is collecting you all happen before you have data.

What it actually costs

Our France plans start at $1.29, with 3 GB over 15 days at $2.38 and 10 GB over 30 days at $6.58.

Orange Holidays: the one case for buying French

France is the one country where the local operator product is genuinely worth considering, because Orange Holidays includes a French phone number with calls and texts.

If a French business needs to reach you, a gite owner, a car hire desk, a restaurant confirming a booking, then a French number solves a real problem that a data eSIM does not.

If you only need data, you are paying for minutes you will not use. Most travellers make their calls on WhatsApp anyway, because the people they are calling are at home on WiFi.

Is a French SIM worth it for a short trip?

Often, genuinely, no. This is the question people ask most about France and the honest answer depends entirely on where your phone plan comes from.

• EU plan: buy nothing. EU roaming gives you your home allowance in France at no extra cost.
• UK plan: check first. Some UK networks kept free EU roaming after Brexit and others reintroduced daily charges.
• US, Canada, Australia, Brazil, most of Asia: buy something, because carrier roaming will charge a daily fee or throttle you.

We sell eSIMs and we would still rather you kept your money if you already have what you need.

Arriving already connected

An eSIM installs at home over your own WiFi before you fly, sits switched off until you land, and connects while the plane is taxiing. You reach the RER with maps and your booking already loaded.

Ours runs on Orange France on 5G, the network with the best rural reach in the country. Validity starts only when it first connects in France, so buying ahead costs nothing.

Does it work in Corsica and the Alps?

Yes, both. Corsica is part of France and covered by the same plan with nothing extra to buy, as are the Alpine resorts.

Ajaccio, Bastia and Porto Vecchio have good coverage. The interior mountain roads of Corsica are among the weakest signal areas in France, so download offline maps before leaving the coast. In the Alps, resort villages are well covered and high lifts are not, which is normal for mountains anywhere.

Coverage around the country

• Paris: 5G across the city and most of the metro.
• Nice and the Cote d'Azur: strong along the whole coast.
• Lyon, Bordeaux, Toulouse, Marseille, Lille: 5G in the centres.
• Loire and Normandy: solid 4G, 5G in larger towns.
• Massif Central and rural Occitanie: thinner, with genuine dead spots.
• Corsica: good on the coast, weak inland.
• TGV routes: signal drops in tunnels and returns quickly.
