Getting online in Paris is usually a choice between using your existing roaming plan, adding a travel eSIM, or buying local prepaid service. I start by checking the home carrier before buying anything: EU/EEA customers may already have Roam Like at Home coverage, while UK and other non-EEA plans depend on their own provider terms. Paris also operates a free municipal Wi-Fi network, useful as backup rather than as your entire connectivity strategy.
- Check your home plan first: EU/EEA Roam Like at Home rules may already cover France, while UK and non-EEA customers need to check their carrier's terms
- A travel eSIM can be installed before departure if your phone is unlocked and eSIM-compatible; a physical prepaid SIM remains a sensible alternative
- Paris Wi-Fi is free to visitors at equipped municipal sites, with two-hour sessions that can be renewed
- Hours
- Mobile service is continuous; Paris Wi-Fi follows the opening hours of each equipped municipal site
- Price
- Compare current carrier/eSIM/prepaid offers for your dates instead of relying on an old fixed weekly price
- Tip
- Download your first-day map, booking confirmations and accommodation address before flying so arrival does not depend on instant mobile activation.
First question: does your existing plan already work in France?
EU roaming rules cover customers of participating EU/EEA operators when travelling elsewhere in the EU/EEA, subject to fair-use and plan conditions. That system also extends to Iceland, Liechtenstein and Norway. The UK is not automatically part of the EU roaming regime, and travellers from Australia, the US and other non-EEA markets need to check their own carrier's roaming package. I do this before shopping for another SIM.
An eSIM is the easiest option only when the phone supports it
A travel or local eSIM can be bought and installed before departure, which removes the airport-kiosk rush. But the phone must support eSIM and must not be locked to another carrier. Keep the installation QR code or app details available offline, and read whether the product includes only data or also a French number, calls and texts.
A physical prepaid SIM still has a place
If the phone lacks eSIM support, you want a conventional French number, or you simply prefer something staff can help activate, compare current prepaid offers from recognised mobile operators. I avoid quoting a universal Paris tourist-SIM price because allowances, validity and promotions change faster than a useful guide can.
Paris Wi-Fi is a real municipal backup network
The City of Paris operates free Paris Wi-Fi for residents and visitors at equipped municipal locations such as parks and gardens, arrondissement town halls, libraries and City museums. The official service says sessions last two hours and can be renewed. Availability still depends on the public site's opening hours and capacity, so I treat it as backup rather than my only connection.
Public Wi-Fi is convenient, not a reason to abandon normal security
Use the same caution you would on any shared network: keep the device updated, prefer encrypted websites, avoid exposing sensitive information unnecessarily and do not assume a network with a familiar name is genuine merely because it appears in the list. For banking or critical account changes, mobile data is the simpler option when available.
Offline preparation is still worth ten minutes
Save your accommodation address, key rail/flight details, insurance contacts and a basic Paris map offline. Download any app-based tickets that allow it. Mobile networks are generally reliable; the point is not to expect failure, but to avoid making the first hour of the trip depend on a QR code trapped in an inbox you cannot reach.
TATS Man's take
I would spend less time hunting for the mythical cheapest SIM and more time making sure the plan activates cleanly, has enough data for maps and works on the phone in your pocket. Reliable beats theoretically cheapest after a long-haul flight.
Cheers, Carpe Diem & land with the map downloaded before the bars light up! 🍻⏳📶

Frequently asked questions
Do EU visitors need a separate SIM for Paris?
Not necessarily. EU/EEA Roam Like at Home rules may let an eligible home plan work in France, subject to the plan and fair-use conditions. Check the home carrier first.
Is Paris Wi-Fi free for tourists?
Yes. The City of Paris says Paris Wi-Fi is open free of charge to Parisians and visitors at equipped municipal sites; sessions last two hours and can be renewed.
Should I buy an eSIM before flying?
It can be convenient if the phone is unlocked and eSIM-compatible. Compare the current allowance, validity and whether the plan includes a phone number rather than assuming all eSIMs work the same way.
