What is an eSIM, and how does it work in Paris?
An eSIM (embedded SIM) is a digital SIM card built into your phone, tablet, or laptop. Instead of slotting in a physical card, you download a network profile from a provider, which connects you to a local mobile network. For Paris, that means you can buy a plan at home, install it in minutes, and arrive already online.
When you buy an eSIM plan the provider sends a QR code or an in-app install link. Scanning it loads the profile onto your device, and from then on the eSIM behaves just like a normal SIM for data. You can keep your usual SIM active at the same time, so your home number still works for calls and texts.
Is an eSIM better than a local SIM card in Paris?
For most travellers, yes. A local Orange or SFR SIM means finding a shop and setting it up, while a travel eSIM installs before you fly and activates the moment you land. You keep your home number on your normal SIM for calls and codes, and use the eSIM for data. France is in the EU, so if you already have an EU plan, roaming may be free under EU rules, so check that first. For everyone else, an eSIM is usually the faster and cheaper option.
Mobile networks and coverage in Paris
France's four main mobile networks are Orange, SFR, Bouygues Telecom, and Free Mobile. Paris has excellent 4G and widespread 5G across the city, from the Latin Quarter to Montmartre, holding up on the Metro, the RER, and out to the suburbs and the airports. Travel eSIMs connect through these local networks, so you get dependable data across the city and on day trips beyond.
Ubigi connects to France's networks for fast, steady data across Paris, while Holafly runs on the same local infrastructure with unlimited data by trip length. Coverage is excellent throughout the city and reliable on day trips to Versailles, Fontainebleau, or the Champagne region.

How to choose the right eSIM for Paris
A few quick checks make it easy to pick the right plan before you travel:
Check your data needs: For maps, messaging, and browsing a 3GB to 10GB plan is usually enough for a city break. For video calls, remote work, or streaming, choose a larger plan or an unlimited option.
Match your trip length: A long weekend suits a small bundle, while a month working from Paris is better with 25GB, an unlimited Ubigi plan, or a longer Holafly day plan.
Already on an EU plan? France is in the EU, so roaming on an EU home plan may be free. If you are outside the EU, an eSIM avoids expensive roaming charges.
Verify device compatibility: Most recent iPhones, Google Pixels, and Samsung Galaxy phones support eSIM. Check under Settings, then Mobile Network, then Add eSIM.
Customer support and setup help
Both providers offer support to get you online quickly. Ubigi has an in-app help centre and email support, plus clear install guides for iOS and Android. Holafly offers 24/7 chat support and a simple app. Whichever you choose, install and test the eSIM before you fly so you land already connected.
How to set up your eSIM in Paris
Setting up your eSIM for Paris takes just a few minutes:
1. Check compatibility: Confirm your phone supports eSIM (most recent models do). Ubigi and Holafly both list supported devices on their sites.
2. Choose your plan: Pick a data size and validity that matches your trip.
3. Install the eSIM: After purchase you receive a QR code or in-app link. Scan or tap to load the profile onto your device.
4. Activate on arrival: Turn on your eSIM line and enable data roaming when you land in Paris. Activation usually starts automatically.
5. Test your connection: Open a map or browser to confirm data is working. If not, restart your phone or toggle airplane mode.
