This guide covers the CDG airport arrival experience. For complete pricing, provider reviews, and plan comparisons, see our Best eSIM for France guide. For Paris-specific coverage and tips, see our Paris eSIM guide.
Charles de Gaulle (CDG) is France's busiest airport and the arrival point for most international travelers visiting Paris. Whether you're landing at Terminal 1, 2, or 3, having mobile data from the moment you step off the plane makes navigating the airport, catching your transfer, and getting into Paris significantly easier.
eSIM vs Buying a SIM Card at CDG
Here's a direct comparison of your two main options for getting connected at Charles de Gaulle:
| Factor | eSIM (Install Before Flight) | CDG Airport SIM Kiosk |
|---|---|---|
| Price (5-7 days) | $4.50, $27 | $20, $35 |
| Time to connect | Instant, connected at landing | 15-30 min (queue + setup) |
| Availability | 24/7, install anytime before flight | 7am-10pm (varies by terminal) |
| Data options | 1GB to unlimited | Typically 5-10GB prepaid |
| Network choice | Orange, SFR, or Bouygues (depends on provider) | Usually limited to one carrier |
| Setup difficulty | 5 min at home on WiFi | Staff assisted, but language barrier possible |
| Late-night arrivals | Works anytime | Kiosks likely closed |
Late-Night Arrivals at CDG
If your flight lands after 10pm, SIM card kiosks will likely be closed. The airport WiFi is your only option unless you've pre-installed an eSIM. Many long-haul flights from North America arrive in the early morning (6-8am), before some kiosks open. An eSIM eliminates this timing risk entirely.
SIM Card Kiosk Locations at CDG
If you do want to buy a physical SIM card at the airport, here's where to find them:
Terminal 1
Terminal 2 (2E & 2F)
The busiest terminals for international arrivals
Terminal 3 (Budget Airlines)
What the Kiosks Sell
The most common product is the Orange Holiday SIM: a tourist-oriented prepaid SIM with 20GB of data, 120 minutes of calls, and 1,000 texts, valid for 14 days. It costs around $25-30 at airport kiosks. For comparison, an unlimited eSIM from Holafly costs $19 for 5 days or $27 for 7 days, with no queue and no physical card to manage.
WiFi at Charles de Gaulle Airport
CDG Airport WiFi
CDG WiFi is functional but not something you want to rely on. It's fine for sending a text to your hotel or checking your transfer details, but too slow for navigation, video calls, or downloading maps. If you didn't install an eSIM before departure, you can use the WiFi to download an eSIM provider's app and purchase a plan, though this is slower and less convenient than setting everything up before your flight.
The Smarter Option: Install Your eSIM Before You Fly
The best approach is to skip the CDG kiosk entirely. Here's how to be connected the moment you land:
Choose a France eSIM Plan
Compare plans in our France eSIM guide. For most Paris trips, we recommend Holafly Unlimited ($19-27) or Airalo 3GB ($11) for budget travelers.
Install at Home on WiFi
Download the provider's app, purchase your plan, and scan the QR code to install. This takes under 5 minutes. Do it the day before your flight.
Land at CDG and Turn Off Airplane Mode
When your plane touches down, switch off airplane mode. Your eSIM automatically connects to the French network (Orange, SFR, or Bouygues depending on your provider). You have data before you reach passport control.
Navigate Your Transfer to Paris
Use Google Maps to check real-time RER B schedules, compare taxi vs train options, or book a ride-share, all while walking through the terminal.
Getting from CDG to Paris with Data
Having mobile data at CDG makes getting into Paris much easier. Here are your transfer options and how data helps with each:
| Transfer Option | Cost | Time to Central Paris | How Data Helps |
|---|---|---|---|
| RER B Train | ~$12 | 35-50 min | Check real-time schedules, track your stop, navigate Metro transfers |
| Roissybus | ~$16 | 60-75 min | Track bus location, check traffic conditions |
| Taxi | $56-65 (flat rate) | 45-75 min | Verify the regulated flat rate, navigate to taxi rank |
| Ride-share (Uber/Bolt) | $45-80 (variable) | 45-75 min | Book and track your ride, communicate with driver |
| Private transfer | $70-120 | 45-75 min | Coordinate with driver, share your terminal location |
RER B Tip
The RER B train is the cheapest way to central Paris, but the CDG station can be confusing. With mobile data, pull up Google Maps for turn-by-turn directions from your terminal to the RER platform. The train runs from CDG every 10-15 minutes and stops at Gare du Nord, Chatelet-Les Halles, and Saint-Michel-Notre-Dame.
Frequently Asked Questions
Where can I buy a SIM card at Charles de Gaulle airport?
SIM card kiosks are located in the arrivals halls of Terminal 1, Terminal 2E, and Terminal 2F. The main operators are Relay stores and SFR/Orange branded kiosks. Most are open from 7am to 10pm, though hours can vary. Expect to pay $20-30 for a basic prepaid SIM with 5-10GB of data.
Is there free WiFi at Charles de Gaulle airport?
Yes. CDG offers free WiFi throughout all terminals, labeled "WIFI-AIRPORT." It's free and unlimited but speeds are typically slow (2-5 Mbps) and it can be unreliable during peak arrival times. It's sufficient for checking email or sending a quick message, but not ideal for downloading large files or video calls.
Should I buy a SIM at CDG or install an eSIM before my flight?
Installing an eSIM before your flight is the better option. You skip the kiosk queue (which can be 15-30 minutes after peak international arrivals), save money ($4-19 vs $20-30), and you're connected the instant you turn off airplane mode. CDG kiosks also have limited operating hours, so late-night arrivals may find them closed.
Will my eSIM work immediately when I land at CDG?
Yes, as long as you installed and configured the eSIM before departure. When your plane lands and you turn off airplane mode, your phone will automatically connect to the French network (Orange, SFR, or Bouygues depending on your provider). You'll have data before you even reach passport control.
How do I get from CDG to Paris city center with data?
With an active eSIM, you can immediately use Google Maps to navigate your options: RER B train (cheapest, ~50 min to central Paris), Roissybus (direct to Opera), taxi (flat rate of 56 euros to Right Bank or 65 euros to Left Bank), or ride-share apps. Having data lets you compare options, check real-time RER schedules, and navigate your route in real time.
