Everything about Paris Charles de Gaulle Airport (CDG): terminals, transport to Paris, eSIM and practical tips.

## Get online at the airport

Install a MerrSIM eSIM for France (from €1.99, 10 GB €9.99) before departure and you’re online the moment you land at Paris Charles de Gaulle Airport — no WiFi hunt, no roaming.

## How an eSIM works

An eSIM is a digital SIM built into your phone: there is no physical card to insert. You buy it online, get a QR code by email and scan it in your settings. Once installed, the profile lives on your phone and activates when you reach France, connecting automatically to a local partner network. You can keep your main SIM at the same time, so your number still gets calls and texts while the eSIM handles data.

## No registration, no shop queue

Many EU countries require identity verification for local SIM cards, which means a queue, a shop and sometimes even a local address. A travel eSIM skips all of that: it is sold as an international data service, with no passport and no contract. You have it ready before you set off for France, so you land and are online immediately — no time wasted at the airport and no risk of surprise roaming bills.

## How much data you really need

For normal use — maps, messaging, social media and the odd video — budget about 300–700 MB a day. A light traveller is fine with 3–5 GB for a week, while anyone doing video calls, streaming or laptop hotspot will want 10–20 GB. In France, download offline maps and use hotel WiFi for big downloads; that way a 10 GB plan comfortably lasts two weeks. If you run out, you buy a new plan in the app with no waiting.

## Activation in a few minutes

Do the install before departure, while on WiFi. Open your phone settings, choose to add an eSIM and scan the QR code you received by email. Label the profile “France” so it is easy to spot. When you land, set the eSIM as your data line and switch on data roaming for it — that is normal for travel eSIMs and adds no fees, because the plan is prepaid. Within seconds you are online, with no need to hunt for public WiFi.
