How to connect

Once on board the TGV ^INOUI1, accessing the Internet is simple:

- Activate wifi in your parameters or settings.
- Select the "_SNCF_WIFI_INOUI" network.
- Confirm the terms and conditions by clicking on "Connect me".
- You can also manually enter the url https://wifi.sncf in your browser to finalize your connection to the TGV INOUI Portal.

How does it work?

Enabling you to enjoy Wifi on board our trains is a technical feat. Indeed, to meet connectivity needs, for which the installation of 4G antennas along the tracks and on board trains is not enough, we launched on-board Wifi in 2016.

In our trains, boxes pick up the 4G signal then transform it into a wifi network before broadcasting it, allowing you to benefit from a stable Internet connection, whatever your mobile operator. To guarantee a continuous connection, additional terminals have also been installed every 3 km on all the main high-speed routes.

In all, our teams deployed the equivalent of 124 km of optical fiber in 304 trains, and installed 18,000 antennas.
