Coverage

## Where TGV INOUI Wi-Fi works, and where it drops

1. TGV INOUI trains have antennas that pick up operators’ 4G and 5G networks.
2. Network coverage can be weak or absent in some areas.
3. Bandwidth is shared, so speeds at 300 km/h are lower than at a fixed location.
4. The TGV INOUI portal at `wifi.sncf` lets you follow your journey, order from the bar and watch content.

The rules

## Data limits, streaming on TGV INOUI

Tips

## Before you board

On board with Kilobat

## Make a shared train link go further

Kilobat is a Mac menu-bar app that shows what each app sends and holds back what can wait. On TGV INOUI Wi-Fi on board:

- **The sign-in page.** When it doesn’t open by itself, the menu bar says **This Wi-Fi wants you to sign in**, with **Open sign-in page**. Turn your VPN on again after you’ve signed in. Free:
- **Why it can’t connect.** When a VPN, iCloud Private Relay or custom DNS hides the sign-in page, Kilobat names the layer that broke: VPN, DNS or the network. Free:
- **See what’s using it.** Every app’s upload and download, live in the menu bar, so you know which one is taking the shared link. Free:
- **Mark it metered.** macOS treats train Wi-Fi as unlimited. Mark it **Metered** and Kilobat skips its own speed tests; with automatic switching, Travel blocks backups and the like on that network. Pro:
- **Send later.** A big upload, such as Dropbox syncing a folder, can wait until you’re on unmetered Wi-Fi again, for up to eight hours while Kilobat is open. Pro:

[Download for Mac ↓](https://kilobat.app/downloads/Kilobat-1.33.1.dmg?via=site)

```
brew install seifip/kilobat/kilobat
```

Pro is $29 once for two Macs, with a 7-day free trial and 14-day refunds. More in [saving hotspot data](https://kilobat.app/save-hotspot-data).

**What is eating your bandwidth?** Live traffic for every app, right in your menu bar. Catch the backup choking your call.

**Hotspot data gone in an hour?** Travel blocks backups, and updaters wait until you’re off the hotspot. The apps keep working.

## Questions

**Is Wi-Fi free on TGV INOUI?**

Yes. Wi-Fi is included with every TGV INOUI ticket.

**What is the TGV INOUI Wi-Fi network called?**

Select `_SNCF_WIFI_INOUI`, then follow the portal steps.

**Does OUIGO have free Wi-Fi?**

SNCF Connect lists Wi-Fi on OUIGO as an add-on you choose when booking, not an included service.

**Why won’t the TGV INOUI Wi-Fi sign-in page open on my Mac?**

A VPN, iCloud Private Relay or your own DNS can keep the page from opening. Turn them off, open `http://captive.apple.com` in Safari, and turn the VPN on again after you’ve signed in. Kilobat shows **Open sign-in page** when a network is waiting for you.
